摘要
在不同胶凝体系的混凝土中,掺入适量的石灰石粉替代粉煤灰、矿粉和水泥,研究了石灰石粉作掺合料对不同胶凝体系下混凝土工作性和强度的影响。试验结果表明,在不同胶凝体系中,均可用占胶凝材料总量10%的石灰石粉取代掺合料或水泥,取代粉煤灰时则可以完全替代。
This paper discussed the influence of limestone powder as admixture on the working performance and strength of cement in different cementing materials by mixing appropriate amount of limestone powder with concrete instead of fly ash,mineral powder and cement.The test results shows that in different gel systems,cementing materials-10 % weight of limestone powder are available in different gel systems to replace admixture of limestone and cement,and fly ash can be completely replaced.
