石灰石石屑代砂混凝土配制技术研究

Study on the Preparation Technology of Concrete Containing Limestone Aggregate Chips

针对湖南省湘西地区缺乏河砂且石灰石资源丰富这一现状 ,研究石屑代砂配制混凝土之技术 .试验结果表明 ,石灰石石屑代砂混凝土的配合比设计基本上可按普通混凝土的配合比设计原则、方法进行 ,但合理砂率及单位用水量需通过试验作适当微调 .

The study of the preparation technology of concrete containing aggregate chips is important to meet the fact that there are little river sand and a lot of limestone in Xiangxi district of Hunan province. The testing results indicated the mix design method of concrete containing aggregate chips is same as that of ordinary concrete, but the reasonable sand ratio and water demand must be adapted through experimental study.
