Study on Properties of Fresh and Hardened Slag Cement Paste

摘要：

The paper studied effect of blast-furnace slag on rheology and hydration properties of blended cement paste.Rheology of blended cement paste with polycarboxylic series (PCS) and sulphamate series (SMS) superplasticizer is tested,appraised effect degree of the dosage and fineness of slag in blended cement by saturation dosage of superplasticizer,fluidity and gradual loss of fluidity.For hardened paste,the study tested development of strength and hydration products,activation effects of gypsum and sodium sulfate,analyzed macro mechanical behavior and micro structure of blend cement made from slag.
