磷渣粉火山灰活性研究

Study on phosphorus pozzolanic activity

粒化磷渣是活性渣,采用火山灰效应比强度、火山灰效应强度贡献率、活性指数等定量指标以及火山灰效应图,来准确地判断与分析磷渣粉掺合料在水泥石中的火山灰效应的大小、影响因素及其规律。结果表明,磷渣水泥石的火山灰效应比强度、火山灰效应强度贡献率、活性指数等均随着磷渣粉的掺量和龄期的增加不断增大,其中在水化早期磷渣粉的火山灰效应呈现负效应。

Grain phosphorus is active, and quantitative indexes, such as pozzolanic effect specific strength, strength contribution rate,activity index and pozzolanic effect form,can be used to judge and analyze phosphorus＇ pozzolanic effect,influence factors and the pattern in hardened phosphorus paste.The result shows that hardened phosphorus paste＇ pozzolanie effect specific strength, strength contribution rate, activity index enhance along with the increase of phosphorus content and age,but at early stage phosphorus has a negative pozzolanie effect.
