多孔硅质岩的火山灰效应

Pozzolanic Effect of Porous Silicon Rock

多孔硅质岩中SiO2 含量约为 90 % ,主要物相α -SiO2 ,晶粒细小 .利用混凝土火山灰效应的数值分析方法定量分析多孔硅质岩混凝土火山效应强度贡献率 ,确定多孔硅质岩的活性大小 。

There is about 90% amount of SiO 2 in porous silicon rock(PSR), whose major mineral is α SiO 2 and fineness is small. PSR powder is tested to be an active additive. The strength contributing ratio of pozzolanic effect in PSR concrete is calculated and the active amount of PSR is determined by means of numerical analysis of concrete pozzolanic effect.
