Influence of Superplasticizer Dosage on Rheological Properties of Fresh Cement Pastes and Properties of Hardened Cement Pastes

摘要

The strength and shrinkage properties of mortars with different superplasticizer were studied. The results indicated that the saturation point was the best dosage of superplasticizer, at which it not only helped to reach highest paste fluidity with minimum superplasticizer dosage, but also reach the highest mortar strength and comparatively lower shrinkage rate.
