Qualitative analysis on the hydration reaction of slag cement by limestone

LIU Xiao-jun,PIAO Ying-mo(Institute of Building Materials,Dandong University,Dandong 118003,China)  
To save cement,making experiment with limestone added in slag cement.The result shows the early hydrated reaction rate of C3S increases with the increase of the replacement ratio and powder degree of limestone in slag cement,but the hydration reaction ratio is equivalent to slag cement at age of 28 days.The hydration reaction of C3A decreases in age of 1 days,but the hydration ratio is equivalent to C3A of slag cement later.The limestone participates at age of 7 day,and is related to the hydration of C3A.
