高性能混凝土及其发展动向

The development of the high performance concrete

由于混凝土技术发展的不平衡性 ,世界不同国家及学者对高性能混凝土的认识也不尽一致 ;而高性能混凝土及大掺量粉煤灰混凝土已成为当今世界混凝土发展的两大主题 ,同时衍生出的绿色混凝土和水工高性能混凝土 ,对今后混凝土的研究与发展也将产生重要影响 ,本文结合水工高性能混凝土中高活性掺合料的研究对上述问题进行了阐述。

Because of no balance in the concrete technological development,various countries and scholars have a different recognition on the high performance concrete.Therefore,the high performance concrete and great addition of fly ash concrete have become two main subjects on the field of the development of the concrete at the present world.At the same time,derivative green protecting environment concrete and high performance concrete used under water will produce an important influence on the study and development of the concrete for the future.The essay focuses on the study of the high activities compound admixtures in high performance concrete used under water to explains the above problems.
