Abstract: The paper forms part of a wider research study directed to explore the combined effect of cement, mineral filler, admixture and their effects on liquidity and resistance to segregation of self compacting concrete (SCC). Several different compositions of cement mortar with/without fillers (limestone and quartz fillers) and with/without superplasticizers were prepared and tested for flow, bulk density and air content. Analysis of heat of hydration and the Average Blaine Specific Surface are presented. It has been revealed that the hydration process is clearly influenced by the presence of fillers. The induction period is generally shorter with an extra peak recorded for limestone filler. These phenomena are less pronounced for quartz filler additions.
