The results show that the mineral admixtures can reduce C3A quantity in the cement material, and the pozzolanic reaction can consume lots of hydration product-Ca2, Which makes specimens close-grained, has obvious prevention function towards the sulfate corrosion. The anti-sulfate corrosion effects of various mineral admixtures from finer to poorer in turn are as follows: 30% fly ash, 30% fly ash + 30% slag, 60% slag, 30% steel slag + 30% slag, 30% steel slag, 30% slag, the blank type.

研究结果表明：加入矿物掺合料降低了试件的胶凝材料中的C3A含量，其火山灰反应消耗了大量的水化产物Ca2，且提高了试件的密实度，对硫酸盐侵蚀具有明显的预防缓解作用；各矿物掺合料的抗硫酸盐侵蚀效果由优到劣依次为：30%粉煤灰，30%粉煤灰＋30%矿粉，60%矿粉，30%钢渣＋30%矿粉，30%钢渣＞30%矿粉，空白样。

The ash from open-field burning or from non-controlled combustion in industrial furnaces usually contains a higher proportion of non-reactive silica minerals such as cristobalite and tridymite, and it should be ground to very fine particles to develop pozzolanic activity.
