摘要
对粉煤灰在氯氧镁水泥制品中应用进行了研究，发现掺加适量粉煤灰可明显改善此胶凝材料的耐水性和泛霜现象，对强度也有一定提高。其原因是粉煤灰中的活性ＳｉＯ２和氨氧镁水泥作用生成ＭｇＳｉＯ３，活性氧化铝形成Ａｌ（ＯＨ）３絮状凝胶，改变了相组成和孔结构．
This paper presents the study on using fly ash In magnesium oxychlorlde product.It is found that a suitable amount of fly ash can greatly improve water resisting,efflorescence and Increase strength.ThereaSOn is that the active SiO2 in fly ash reaCtS With magnesium OXyChlorlde pfodllCt to form MgsiO3 and Al(OH)3 ,WhiCh Change the pheses and porosity structure of the products.
