摘要
研究了矿渣粉和生石灰粉用量对3种粉煤灰配制的胶凝材料强度的影响,并进行了相关产品的生产和性能试验.结果表明:适量矿渣粉能显著提高大掺量粉煤灰胶凝材料的早期强度尤其是抗折强度;粉煤灰烧失量是影响粉煤灰产品强度的主要因素.
The influence of slag powder and quicklime powder on strength of three kinds of fly ash binding materials was investigated and production＇of related product was carried out, test of properties was conducted. The results show that mixing proper amount of slag powder into fly ash binding materials can greatly improve the flexural strength of the materials, which solves the problem of low flexural strength of fly ash products with high use level of fly ash. And the further research analysis indicates that ignition loss of fly ash is the main factor which affects the strength of fly ash products.
