High performance concrete (HPC) is of great topical interest to the construction industry worldwide, with applications in high-rise, offshore, nuclear and bridge structures, and in precast concrete. Among the benefits of HPC are improved workability and strength, leading to faster and more economical construction; more durable concrete, especially important for bridges, offshore and nuclear structures, and highways; and improved structural characteristics, which allow more economical and efficient structural designs. The French national project, "New Developments for Concrete", is providing important insights into the materials characteristics of high performance concrete, and also of the structural behaviour of a number of major buildings and bridge structures. This book contains a series of 35 selected reviews and reports on HPC by the leading materials scientists and engineers contributing to the French programme. Previously, they have only been available to delegates at seminars and meetings in France but the most valuable have been edited and translated into English in order to make the results of the programme widely available.

This volume represents the proceedings of the second in a series of discussion meetings convened by The Royal Society with the aim of reviewing the ways in which human needs and national expectations can be served by technological developments in the 21st century. "A Global Strategy for Housing in the Third Millennium" provides an authoritative account of the demand for housing in rich and poor countries, and shows how that demand may be satisfied by well co-ordinated social and technological policies. It provides basic principles in good housing design and social attitudes towards housing. The contributors - leading authorities from North America, Europe and Japan - predict future contributions of technology to housing for basic needs and comfort in temperate and extreme climates. New materials, construction processes and the increasing use of electronics in building services and overall planning are also central to this book. The wide range of viewpoints from which future technical developments in housing are approached should make this book beneficial for those professionally concerned with the planning, construction and management of housing.

This edition has been revised throughout to take account of recent changes and to incorporate amendments required due to the publication of the revised BS 5328. The manual provides information on all aspects of the ready-mixed concrete industry, from basic materials and their properties to the production, quality control and use of ready-mixed concrete. Discussion of the qualities of concrete and the achievement of quality requirements leads to the consideration of specifying concrete quantities. Attention is then turned from production to delivery. The authors discuss arguments for choosing ready-mixed concrete, and deal with the fundamental issues of obtaining quotations, ordering and handling. While providing a detailed ready reference, this book also gives the reader a perspective on the industry as a whole.

It is becoming increasingly difficult and expensive for demolition contractors to dispose of building waste and demolition rubble. For environmental reasons, public authorities are looking for ways of reusing these materials. The purpose of this book is to make the construction industry and public authorities aware of the technical possibilities for recycling of demolished concrete and masonry. It also shows how localized cutting and partial demolition of concrete structures can be carried out. Recycling of demolished concrete and masonry consists of three state-of-the-art reports which have been prepared by members of an international RILEM committee: recycled aggregates and recycled aggregate concrete; recycled masonry as aggregate for concrete; and blasting of concrete - localized cutting in and partial demolition of concrete structures. The three reports review a range of research and practical experience on the subjects, much of which has not been easily accessible before. They are intended for use by building industry professionals' involved in design and construction at all levels. They should be of particular use to demolition and recycling contractors, and to concrete tech

This book offers a unique treatment of building insulating products and the integration of these products with building components. This book was written for all those involved in building design, specification, construction, and commissioning, providing them with an understanding of and appreciation for the wide variety of thermal insulation products and technologies available for use in all types of buildings. The book proceeds from basic definitions and discussion of heat-transfer topics and thermal insulation concepts, to the design and use of these products. The impact of thermal insulation on dynamic building performance, including factors other than heating and cooling, is also discussed. The book does not require an advanced mathematical background. The authors provide sufficient information to provide a qualitative understanding, with more mathematical sections included for those interested in modeling and analysis. The basic physics associated with heat transfer in buildings are presented, along with the steady-state and transient analysis techniques needed for the effective implementation of thermal insulation and assemblies. Modern building design involves the integration of comfort, safety, economics, durability and cost considerations, all of which impact the selection and use of thermal insulation materials in buildings. In addition to theoretical explanations of the underlying science, the book details the properties and application of new thermal insulation materials, including vacuum panels, gas-filled panels, aerogels, phase-change materials, and radiation control technologies. Given its scope, the book will be of interest to researchers and building engineers wishing to understand the latest technologies and materials available, so as to achieve reduced energy consumption in commercial and residential buildings.

This volume emphazises the most early 1990s advances in fracture mechanics as specifically applied to steel bar reinforced concrete. Fracture mechanics has been applied to plain and fibre reinforced concrete with increasing success over recent years. This workshop extended these concepts to steel bar reinforced and pre-stressed concrete design. Particularly for high strength concrete, which is a very brittle material, and in the case of large structural members, the application of fracture mechanics appears to be very useful for improving the present design rules. The participants at the Turin workshop contributed expert opinions in four selected areas for which a rational approach, using fracture mechanics, could introduce variations into the concrete design codes: size effects; anchorage and bond; minimum reinforcement for elements in flexure; and shear resistance. The 23 chapters logically address these themes and demonstrate the unique ability of fracture mechanics to capture all the experimentally observed characteristics.

This encyclopedic volume covers almost every phase of piping design - presenting procedures in a straightforward way.;Written by 82 world experts in the field, the Piping Design Handbook: details the basic principles of piping design; explores pipeline shortcut methods in an in-depth manner; and presents expanded rules of thumb for the piping design engineer.;Generously illustrated with over 1575 figures, display equations, and tables, the Piping Design Handbook is for chemical, mechanical, process, and equipment design engineers.

"Managing Change in Construction Projects: a knowledge-based approach" offers a new perspective on construction project change by viewing the process of change management as a knowledge-intensive activity, where team members bring their tacit and explicit knowledge into the situation; share, create and capture this collective knowledge for future re-use in similar situations.

Through this knowledge-based approach, construction teams can successfully resolve and learn from change events, leading to an overall improved performance of the industry.

The book will make a significant contribution to our understanding of construction project change by offering new theoretical and practical insights and models grounded in results of case studies conducted within two collaborative construction project team settings.

By demonstrating how the social construction of knowledge works in construction settings, the authors challenge the prevailing change management solutions based on 'hard' IT approaches. They put forward a balanced view that incorporates both IT-based and socially constructed approaches to effective management of construction project change.helps construction managers to improve and learn through the process of construction project changepresents new theoretical models and offers practical guidelinesfirst research-based book to directly address project change from a knowledge-based perspectivedraws on detailed studies with construction companies, including Ballast Construction and Kier Constructionencourages a move from the information driven, process integrated approach to a knowledge-based view

48 papers are subdivided into seven chapters: Production, technology and properties; Pore structure and properties; Heat and mass transfer; Crack formation and durability; Reinforced components; Masonry; Ecology and new developments. A comprehensive bibliography on research, technology and applications of autoclaved aerated concrete with 332 references is included. The present state of knowledge on specific properties and ecological aspects of an interesting building material is outlined.

This text is a successor to the author's "Workability of Concrete" published in 1976 and, again, is written specifically for practising engineers and concrete technologists. It incorporates the results of a further 15 years research and develops the treatment of workability as a property to be measured in terms of two constants, which was introduced in the earlier book. The scientific basis is simply explained and used for the description of practical methods and apparatus. This leads to elucidation of problems surrounding the topic of workability and to an account of the potential for quality control. The validity and limitations of standard methods of workability assessment are fully considered and there are several chapters on the effects on workability of the properties and proportions of mix constituents. This book should be of interest to concrete technologists in universities and colleges, ready-mixed concrete, precast concrete and admixture suppliers, testing laboratories, consultants, contractors and specifying authorities.

This text describes the underlying behaviour of steel and concrete bridge decks. It shows how complex structures can be analyzed with physical reasoning and relatively simple computer models, and without complicated mathematics. In recent years the computer methods of grillage and space frame have become very popular and accessible as microcomputers and software have developed rapidly. In this second edition, the intrinsic safety of these methods when used in a systematic manner is explained. New chapters have been included on the analysis of distortion of box girder bridges, on the stiffnesses of supports and foundations, and on integral bridges. The chapter on beam decks and frames now includes demonstrations of the influence of foundation stiffnesses on the frame behaviour of a portal bridge and an arching structure. Coverage of beam-and-slab bridges has been enlarged to explain "torsionless design" which simplifies the design of some bridges. New examples illustrate the grillage analysis of a composite bridge using AASHTO type prestressed concrete girders, and of a composite steel deck. Additional comparisons between grillage and finite strip analyses of cellular structures are

The 1990s will be a challenging decade for the surveying profession.

The conference provided a forum to discuss recent advances and trends in the analysis, design and construction of all types of metal structures. This volume contains 18 of the papers presented at the conference. Invited Lectures on the state-of-the-art surveys have been provided by well-known experts in their respective fields. The coverage is extensive and topics include Bridges, Building Floor Systems, Concrete Filled Hollow Sections, Aluminium-concrete Systems, Composite Members to Earthquake Loading, etc.

The deterioration of cement and concrete as a result of the alkali-silica reaction ("concrete cancer") is one of the major problems facing civil, structural and mechanical engineers involved in the design, construction, repair and maintenance of structures. It is a global problem, and in this book, case studies from both developed and developing countries have been selected to provide an insight into how variables such as climate, geology, construction materials and methods, and building practice, have a bearing on the magnitude of the problem and an influence on remedial measures. This book is a source of reference for civil, structural and mechanical engineers, designers and researchers.

Concrete is one of the principal construction materials used world-wide. Although developments in materials and performance have widened the scope for the use of concrete, they have also affected its properties, particularly in the long term. From this it becomes clear that quality control, which is of vital importance for the building industry in general, needs special attention in its application to concrete structures. The importance of establishing comprehensive quality assurance systems both nationally and internationally is becoming increasingly recognized. Such systems need to take account of the contractual relationships in the industry in order to function effectively. International harmonization of standards and regulations is also putting greater emphasis on such systems. This book forms the proceedings of the Second International Symposium on Quality Control of Concrete Structures which was held in Ghent, Belgium, in June 1991. The volume brings together new information on technical developments, research and practical experience on the following topics: quality management, early age properties of concrete, durability, quality assessment, statistical approaches.

This work reviews methods for the experimental determination of concrete toughness and presents theories and models suitable for describing cracking and fracturing phenomena in plain and reinforced concrete. Test methods based on classsical linear fracture mechanics cannot be applied to laboratory sized concrete specimens. The book compares the currently used methods and presents recommended test procedures for mode I fracture/toughness using notched beam and other specimens. Crack propagation under mixed-mode loading (Mode II) is discussed and current test methods are extensively reviewed. Effects of loading rate, temperature and humidity effects are treated in a separate chapter. The book concludes with descriptions and recommendations of techniques for detecting the fracture process zone in concrete, in particular, pulse velocity and laser interferometry techniques. The introduction of the concepts of fracture toughness and fracture energy into structural concrete design codes means that the experimental determination of fracture porperties is ceasing to be an academic exercise and is becoming a technical need. This book has been prepared by RILEM Technical committee 89-FMT and

This volume sets out to present recent research findings on the applications of fracture mechanics to concrete structures. Papers from international contributors describe existing and new modelling techniques in the analysis of concrete materials and structures. Topics discussed include structural modelling, bending, shear, bond and anchorage. The book forms the proceedings of a RILEM workshop held in Sweden in 1989. It is dedicated to Professor Arne Hillerborg, whose contribution to fracture mechanics is also reviewed.

The production of concrete has in recent years shifted from the site to central production plants. This has improved efficiency but has also given rise to new problems, such as the influence of temperature and time on consistency of fresh concrete. The separation of mixing and transportation from on-site placing and curing requires better means of measuring and defining the state of the concrete at the time of delivery. In addition, new types of cements and admixtures are being widely used. This book forms the Proceedings of the RILEM Colloquium held in Hanover, Germany in October 1990 to review the state-of-the-art of the properties of fresh concrete. Papers from 18 countries in Europe, North America and the Far East are included. This book should be of interest to cement and concrete technologists and researchers, civil engineers, manufacturers and suppliers of cement, concrete and admixtures, research institutes, test houses and rheologists.

Testing of materials and manufactured items is a key element in the process from standard specification through control and verification during manufacture to trade in actual products. In particular, the validity, reliability and economic aspects of testing are of importance. This process is becoming more urgent with the development of the European market and other developments in international trade. Considerable progress is being made in setting up cooperative agreements and networks both bilaterally and multilaterally between countries, covering reference materials, and calibration, accreditation and quality assurance of laboratories, equipment and staff. This book contains invited contributions from many of the individuals and organizations most closely involved in these international developments. Also included are papers and case studies from all parts of the world discussing particular aspects of test quality of construction, materials and structures. The volume should be useful for those responsible for managing and carrying out testing in commercial, industrial and research laboratories, and also for anyone with an interest in international harmonization of technical stand

Calcium aluminate cements are used for many special applications in the construction, civil engineering and refractory industries because of their ability to gain strength rapidly and to withstand aggressive environments and high temperatures. Research into their properties and behaviour in many countries is presented in this book, which includes papers from an International Symposium held in London, A special feature is a major review paper by Lafarge Special Cements presenting the current state of knowledge on the materials. Other papers deal with clinker, hydration, admixtures, calorimetry, durability, blended systems and other aspects. The book is dedicated to the late Henry Midgley whose research into calcium aluminate cements at the Building Research Establishment made an important contribution to the understanding of their behaviour.

Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe - adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.

This book covers execution of mega industrial projects especially in oil and gas industries covering engineering, procurement, construction, commissioning and performance testing. It enumerates various tasks and deliverables under each discipline and sub-disciplines to define the detailed scope of work, supplies and services, as per level III of Prima Vera Schedule developed from the contract-based schedule. It gives an overall idea of how a project rolls out from commencement date to initial acceptance and executed practically with total contractor's scope of work broken down into tasks/activities at level III platform, while highlighting that support for fool proof project execution.

Chemical admixtures are used to modify the properties and behaviour of fresh and hardened concrete. They can enable concrete to be placed more economically, by reducing the plant and labour needed or by allowing modifications to the mix. They are also used to achieve special properties, such as high strength or freeze-thaw durability. Research and development is underway in many parts of the world, looking at fundamental effects of admixtures on cement hydration and rheology, the technological benefits of using admixtures in concrete and the long-term behaviour of concrete containing admixtures. This book draws together reports on research studies into the use of chemical admixtures to improve the properties of concrete. It includes papers from leading research institutes and materials specialists from around the world on six main topics: workability, setting, strength, durability, other properties and technology. The papers were presented at an International RILEM Symposium held in Barcelona, Spain, in May 1990. This book should be of interest to concrete technologists, civil engineers, suppliers of admixtures, ready-mixed and precast concrete materials researchers.

This volume consists of papers presented at the International Conference on Recent Developments in Fibre Reinforced Cements and Concretes, held at the School of Engineering, University of Wales College of Cardiff, UK, 18-20 September 1989.
