Activation strengthening agent applied to cement with high-volume limestone

The present invention provides a dosage of limestone cement applied to a large activation enhancers include 5wt% ~ 8wt% alcohol amines, 10wt% ~ 15wt% of the lignin based polyol herbs, 10wt% ~ 25wt% of aluminum, 5wt% ~ 20wt% of iron salt, 40wt% ~ 65wt% of water. Since only material content alcohol amines 5wt% ~ 8wt%, and herbal inexpensive lignin based polyol, adequate sources, thus enhancing cost low activation invention. Secondly, activation enhancer of the invention help to improve the strength of cement and limestone Volume hardened cement based slurry compressive strength. Activating enhancer of the present invention is applied to the cement, limestone addition up to 20% to 30%, to improve the yield of large limestone cement Volume station more than 15%, compressive strength 3 days and 28 days were increased more than 15% .
