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.

由开阔场地燃烧或在工业炉中不加控制地燃烧得到的灰通常含有较高比例的非反应性二氧化硅矿物质，例如方石英和鳞石英，而且，要发展火山灰活性，它应该被研磨成很细的颗粒。
