摘要
主要讨论了矿物掺合料在水泥砂浆中的填充机理,并且以粉煤灰、矿渣粉及硅灰单一组分、复合组分考察其对水泥胶砂强度及微观结构的影响.研究表明,不同细度的矿物掺合料掺入到水泥浆体中后,可以优化粉体的次级颗粒级配,提高密实度.从而表现出水泥砂浆的强度得到提高,微观结构趋于密实.
Filling mechanism of mineral powder, silica fume and their compounds admixture in cement mortar was discussed,with fly ash, superfine slag filling into cement mortar to study their influence on the strength and microstructure of cement mortar. It is demonstrated that the different mineral admixtures can improve the secondary particles size distribution of cementations materials,and then improve the density of cement mortar. So the strength of cement mortar increased and the microstructure of cement mortar get denser.
