This book presents the work done by the RILEM Technical Committee 227-HPB (Physical properties and behaviour of High-Performance Concrete at high temperature). It contains the latest research results on the behaviour of high-performance concretes at high temperature. The book presents the state of the art of experimental data on High-Performance concretes and it collects and synthesizes useful data about concrete behaviour at high temperatures. The book is divided into independent chapters dealing with degradation reactions in concrete exposed to high temperatures; mass transport properties; thermal properties; and mechanical properties. The results presented especially target a group of users composed by universities and testing laboratories, building material companies and industries, material scientists and experts, building and infrastructure authorities, designers and civil engineers.

The purpose of this study is to develop economical and high-quality ultra high-strength concrete and to improve the workability of this concrete. Consequently, admixture of four types - silica fume, alum-type mineral, fly ash and micropowder blast furnace slag - were used. In part I, the effects of factors - dosage rate of admixture, type of cement, type of aggregate, water-to-(cement + condensed admixture) ratio and dosage rate of high-range water-reducing admixture - on mechanical properties, deformation and dry shrinkage of ultra high-strength concrete are discussed and date concerning mix proportion design were determined. In part II, the effects of the order of adding the concrete's constituent materials during mixing and the time at which the high-range water-reducing admixture and mineral admixtures were added on the flowability and the segregation of the component materials of the fresh concrete were evaluated. The paper also propose a practical mixing method for ultra high-strength concrete.

When produced correctly, concrete can be extremely strong, with high load-bearing capacity and superior durability. Another noteworthy property is the relatively low amount of energy and resources consumed during production. Super-High-Strength High Performance Concrete brings together the results of a major research project by the National Natural Science Foundation of China and the Doctoral Foundation of the Ministry of Education of China. This ten-year project explored the properties, performance, and potential of super-high-strength high performance (SHSHP) concrete. With a view towards improved production that optimizes the strength and durability of concrete, the book presents a host of topics on the cutting edge of concrete research. These include: A new method for the specific strength analysis of the pozzolanic effect of active mineral admixtures Analysis of the strength composition of SHSHP concrete Optimization of raw materials and mix proportion parameters for strength and flowability Analysis of the mechanical properties, deformation, and durability of SHSHP concrete Methods for decreasing autogeneous shrinkage Testing methods for SHSHP concrete The book concludes with a consideration of the practical and economic benefits of these optimized concretes. A systematic study of the different aspects of this essential commodity as well as the future direction of concrete science and technology, this book is a valuable resource for material scientists and engineers engaged in developing better structures.

High Strength/High Performance Concrete (HSC/HPC) continues to be the object of particular interest and extensive research, and its use in construction is increasing continuously. fib Bulletin 42 summarises the available information on the material behaviour of HSC/HPC, and develops a set of code-type constitutive relations as an extension of CEB-FIP Model Code 1990. Literature on experimental data and international guidelines, standards and recommendations were reviewed, and already-existing constitutive relations and models were evaluated. In addition to a number of material laws chosen and adjusted for this report, some new constitutive relations were developed based on the collected data. The criteria for the choice of the existing relations as well as the development of the new constitutive relations involved their simplicity and operationality (code-type mathematical formulations). Furthermore, they had to be physically sound and if possible describe the behaviour of both high-performance and normal strength concretes by a unique relation. Finally, compliance with the specifications given in the CEB-FIP Model Code 1990 was examined. This State-of-art report is intended for engineers and represents a summary of the relevant knowledge available to and possessed by the members of the Task Group at the time of its drafting.

This practical book from a highly experienced author presents clearly the means and methods for designing, producing and using high-strength concrete. High-strength concrete offers many benefits. Higher compressive strengths allow for a reduction in the cross-sectional dimensions of columns and walls in buildings. Its greater stiffness allows for increasing building heights while controlling sway and occupant comfort. Civil structures such as bridges have benefited from greater span lengths, shallower beam sections, wider girder spacing, and extended service life. Illustrated with real life examples, through documented case histories, High-Strength Concrete will be a valuable resource for contractors, producers, inspection agencies, as well as engineers and researchers.
