Super - High - Strength High Performance Concrete







Preface

In 1992, the National Natural Science Foundation Committee issued a

guide for application to the 1993 National Natural Science Foundation,

whereby a key project for the eighth 5-year plan, titled “Research on

Structure and Mechanical Performances of Super- High- Strength Concrete,”

was listed and a study on 90- to 100-MPa super- high- strength concrete was

required. The Foundation Committee, Ministry of Railway, Ministry

of Construction, and the National Bureau of Building Materials jointly

sponsored this project with total funding of RMB 1.1 million yuan. The

author (his affiliation at that time was with Chongqing Jianzhu University)

participated in this project. Subsequently, he took part in the project’s

defense. Finally, Tsinghua University (the leading institution on the project),

the Research Institute of Railway, the China Research Institute of

Materials, and Chongqing Jianzhu University won this project jointly and

it was divided into several parts: The author was in charge of the part to

study the highest strength of concrete (90 to 110 MPa) with funding of

RMB 0.2 million yuan. One year later, this project was renamed Research

on Structure and Mechanical Performances of High- Strength and High-

Performance Concrete (59338120). In 1999, the author won a doctoral

program-funded project from the Ministry of Education with total funding

of RMB 40,000 yuan. With the support of these two projects, the author

and his colleagues succeeded after great effort in producing 90–150 MPa

super- high- strength and high performance (SHSHP) concrete. Their research

work covered different aspects of SHSHP concrete and some successes and

important progress were achieved. This book is based on the results of

these two projects and review of the related literature data.



In this book, the close relationship between modern concrete and modern

civil engineering is described in brief; the main direction for further

development of concrete science and technology, that is, pursuing high

strength and super- high strength as well as durability and super durability,

is set forth; the preparation approach and principles of SHSHP concrete

are expanded upon; the composition and strength performance of calcium

silicate hydrates are described in detail; the effect of the pozzolanic reaction
