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.

The papers presented deal with the general methods and techniques, from a range of disciplines, as they can be applied to specific engineering and fire safety situations. The circumstances described include a variety of large scale plant applications in the petrochemical industry. As such this text is a reference for fire engineers, petroleum engineers and legislators working in multi-disciplinary design engineering teams. This text addresses five major areas of importance on and offshore: risk assessment, operations and operational safety, research, risk reduction and design safety, detection and control and protective systems.

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

In this do-it-yourself manual for homeowners, masonry contractors, and restoration specialists, Cramb drew on his fifty years of life experience in the craft to cover restoration techniques for historic structures in the U.S. and Britain. The book covers various types of stone, stone-cutting, and traditional mortar mixes for walls, foundations, and buildings.

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

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.

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.
