Study on the Influence of Admixture on Chemical Shrinkage of Cement Based Materials

Abstract:

The influences of fly ash, phosphorus slag powder and slag powder on the chemical shrinkage were researched in this paper. The results indicated that chemical shrinkage of cement paste was mainly relative to the mineral composition of cement, and three kinds of admixture could all make chemical shrinkage of cement paste reduce in early stages, but the chemical shrinkage of cement paste increased in later stages after mixing slag powder and phosphorus slag powder, and the activity of slag powder was higher than phosphorus slag powder, and fly ash could be used to inhibit chemical shrinkage of cement paste. The prediction model of chemical shrinkage of cement based materials was established.
