透水混凝土原材料选用的质量控制要点都有哪些呢?

发布日期:2019-06-13 作者:来源于网络 点击:

透水混凝土搜狐足彩在满足强度要求的同时,还需要保持一定的贯通孔隙来满足透水性的要求,因此在配制时除了选择合适的原材料外,还要通过配合比设计和制备工艺以及添加剂来达到保证强度和孔隙率的目的。透水混凝土由骨料、水泥、水等组成,多采用单粒级或间断粒级的粗骨料作为骨架,细骨料的用量一般控制在总骨料的 20% 以内;水泥可选用硅酸盐水泥、普通硅酸盐水泥和矿渣硅酸盐水泥;掺合料可选用硅灰、粉煤灰、矿渣微细粉等。投料时先放入水泥、掺合料、粗骨料,再加入一半的水用量,搅拌 30s ;然后加入添加剂(外加剂、颜料等),搅拌 60s;最后加入剩余水量,搅拌 120s 出料。
