Influence of Limestone Powder on the Performance of Cementitious Materials

摘要

This paper study on the mortar strength, particle gradation and mortar fluidity of binary and ternary systems for cementitious materials with limestone powder or fly ash, analyze the influence of limestone powders with different specific surface areas and contents on the performance of cementitious materials; and research the performance of limestone powder in cementitious materials by means of micro analysis. The result shows that the limestone powder can not only work as the filling material, but also speed up the early hydration of cement in the cementitious material system.
