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 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 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.

Proceedings of the International Conference on Steel and Aluminium Strucutres, ICSAS 91, Singapore 22-24 May 1991. The complete proceedings are available in three volumes: steel structures, aluminium structures and composite steel structures. The conference was organised by the Department of Civil Engineering, National University of Singapore sequel to the one held in Cardiff, UK in July 1987. It was co-sponsored by the International Association for Bridge and Structural Engineering, the Institution of Civil Engineers, the Institution of Engineers, Singapore, the Institution of Structural Engineers, the Steel Construction Institute, UK, the Singapore Structural Steel Society and the University of Wales College of Cardiff. The conference provided a forum to discuss recent advances and trends in the analysis, design and construction of all types of metal structures.

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. Increased competition from new sources, a wide range of technological changes, new developments in the market place present a challenge to the profession. In order to meet these challenges, surveyors must keep up to date with the state of the art. By presenting a broad view of both good practice and research at the forefront of construction investment, procurement and performance, this book addresses recent techniques and technology which enable property to be valued and managed and buildings to be built as effectively and efficiently as possible. With over 25 contributions from both the academic world and from professional practices, it presents insights from people throughout the profession in the key areas of valuation, finance and risk; information technology management and the valuation; and technology.

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.

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.

Innovating Construction Law: Towards the Digital Age takes a speculative look at current and emerging technologies and examines how legal practice in the construction industry can best engage with the landscape they represent. The book builds the case for a legal approach based on transparency, traceability and collaboration in order to seize the opportunities presented by technologies such as smart contracts, blockchain, artificial intelligence, big data and building information modelling. The benefits these initiatives bring to the construction sector have the potential to provide economic, societal and environmental benefits as well as reducing the incidence of disputes. The author uses a mixture of black letter law and socio-legal commentary to facilitate the discourse around procurement, law and technology. The sections of the book cover the AS IS position, the TO BE future position as predicted and the STEPS INBETWEEN, which can enable a real change in the industry. The rationale for this approach lies in ensuring that the developments are congruent with the existing frameworks provided by the law. The book proposes various steps that the industry should seriously consider taking from the current position to shape the future of the sector and ultimately create a better, more productive and sustainable construction industry. This book is a readable and engaging guide for students and practitioners looking to learn more about construction law and its relationship with technology and for those seeking a platform for graduate studies in this area.
