摘要：

The presented study explores the effect of limestone powder (LP), finely blast furnace slag (BFS) and natural pozzolan (NP) on mortar rheology and the interaction of these additions with polycarboxylic-based superplasticizer (PC). It was found that LP and BFS are more effective than NP. The viscosity and yield stress of mortar are obviously decreased with increasing dosage of PC. PC superplasticizer loses its positive effect where NP is added and becomes more effective with LP and BSF. Mathematical relationship is proposed to express the variation of each rheological parameter which provides a more convenient prediction with an acceptable accuracy. (C) 2014 Elsevier Ltd.
