摘要：
It was found that silica fume can reduce the maximum hydration heat release rate of cement by microcalorimetry, inhibit CAH10, promote the generation of C3AH6 and str & auml;tlingite C2ASH8, or promote the conversion of CAH10 to C3AH6. Sodium tripolyphosphate can retard the early hydration of cement, have a slight effect on 1 d hydration products of cement and inhibit the generation hydration products. Sodium tripolyphosphate and silica fume can promote the early hydration of cement, advance the formation of C2ASH8 or the conversion from CAH10 to C3AH6 at 1 d.
