Effect and Action Mechanism of Superplasticizer on Foamed Cement

Abstract:

The ordinary Portland cement was used to prepare foamed cement by the chemical foaming method. In this paper, the effect of superplasticizer on the water absorption and softening coefficient of foamed cement has been studied. The results show that the superplasticizer could improve foam structure, reduce the water absorption, and enhance the compressive strength and softening coefficient. The water resistance could be improved. When the dosage of superplasticizer was 0.3% (the quality of cement), compared with blank sample, the water absorption reduced 27.9%. When the softening coefficient was 0.68, softening coefficient increased 19.2%. The action mechanism of superplasticizer has been explored.
