About 700 000 m3 of pumpable concrete, which was produced by a high-range water-reducing admixture (HRWRA) and relatively low-strength cement, was used in the Xiao Lang Di water conservancy project. The concrete achieved a 28-day compressive strength as high as 90 MPa, a slump of 20 cm, and almost no slump loss in 2.5 h after mixing, as well as good freeze-thaw durability. The paper describes in detail the mix proportions, the method to control slump loss, and the related mechanical properties.

Recent developments have made a new generation of high-strength concrete a viable material for routine construction. The two principal developments are high-range water-reducing admixtures, which permit the placement of concrete of very low water-cement ratio, and silica fume, a pozzolan of extremely high fineness. The advent of this high- strength concrete has put requirements for strength and durability in conflict. Because entrained air reduces the strength of concrete, builders seek to eliminate or limit the use of entrained air. There are those who argue that high-strength concrete is of such a quality that entrained air is unnecessary. Much of the high-strength concrete currently being used is in buildings, where the question of durability is minor. The question, however, cannot be avoided in exposed highway structures. Service records of non-air-entrained high-strength concrete exposed to freezing are not conclusive. Hence, this report synthesizes the available knowledge on the subject. Its aim is to provide guidance to those who wish to use high-strength concrete in typical highway applications and to indicate where further information is needed.

This book forms the proceedings of the international workshop to be held in Essen, Germany. This workshop summarises the conclusion of the technical committee's investigations into the resistance of concrete to freeze-thaw attack, specific in this to resistance with or without de-icing chemicals. It presents the RILEM recommendations on testing the freeze-thaw and de-icing salt resistance of concrete.

This book has been prepared with the aim of integrating information about the chemistry and application of concrete superplasticizers in a manner relevant to concrete engineers and technologists. The opening chapter introduces basic aspects of concrete science as background for what follows. Chapters 2-4 discuss the chemical synthesis of superplasticizers, methods used to characterize those chemicals, and techniques for evaluation of their effect in cementitious systems. Subsequent chapters cover: the influence of superplasticizers on hydration of cement materials; rheology of cementitious systems; issues related to the mode of action and compatibility of superplasticizers; the effect of superplasticizers on fresh concrete; mechanical properties and durability of concrete; innovative applications of superplasticizers in concrete; superplasticizer dispensing, specifications, and standards; patents related to superplasticizers; and current and future trends in the use of superplasticizers in concrete.
