钢渣微粉在粉煤灰加气混凝土中的应用研究

摘要

The use of steel slag powder in fly ash aerated concrete is researched by experiment, it shows that the steel slag powder need larger water when it has a higher specific surface area, the suitable amount of steel slag powder instead of the fly ash is 40%, which leads to the aerated concrete has a good hydration product composition, and excess replacement will make the quantity of C-S-H is lower.%将钢渣微粉应用于加气混凝土中，通过实验研究发现：钢渣微粉较高的比表面积使其需水量偏大，钢渣微粉取代粉煤灰的适宜量为40%，适量钢渣微粉取代粉煤灰可使加气混凝土具有良好的水化产物组成与结构，过量的钢渣微粉取代粉煤灰会导致加气混凝土水化产物C-S-H凝胶数量的大幅度减少。
