摘　　要：自密实高性能混凝土以较大的流动性、较好的稳定性、优良的填充性及间隙通过能力等优点越来越被建筑行业所看重,然而各地区原材料在组成、性质及施工条件上都存在着不同程度的差异,因此,根据各地区的具体情况,研究与发展本地区自密实混凝土有着特别重要的意义。通过对自密实混凝土的配合比试验研究,具体分析了减水剂含量、砂率、粉煤灰含量、硅灰含量、水胶比等主要参数,以及其对自密实混凝土基本力学性能的影响。With advantages such as great liquidity,good stability,excellent gap filling and strong gap through capacity,self-compacting concrete of high performance is increasingly valued by the construction industry.While,because of the different composition,nature and constructive conditions of raw materials in different places,it is particularly important to make researches and help develop the self-compacting concrete of high performance in this region.This paper intend to analysis the main influential parameters such as the content of water-reducing,silica and coal ash,and the percentage of sand and glue through the experimental study of mix proportion on self-compacting concrete;and also make research on the basic mechanical properties of it.
