Study on the Adaptability Between the Amount of C₃S Mineral in Alite-Sulphoaluminate Cement Clinker and the Fly Ash

Abstract:

The paper studied the adaptability between alite-sulphoaluminate cement clinkers with different amount of C₃S and the fly ash admixture. The results showed that: with a fixed content of C₃S, the setting time of the cement delayed, and the compressive strength of the cement decreased with increasing amount of fly ash admixture. With a fixed content of the fly ash admixture, the setting time of the cement delayed, the compressive strength of the cement increased with the increase amount of C₃S, and the lowed percentage of the strength decrease at each ages; With addition of fly ash admixture, the early compressive strength of the cement decreased more, while the later compressive strength decreased less. Clinker with higher C₃S content showed better adaptability with high addition amount of fly ash admixture.
