The influence of the combination of granulated blast furnace slag (GBFS), fly ash (FA) and silica fume (SF) on the characteristics of Ordinary Portland Cement (OPC) pattes was investigated. The results showed that the incorporation of GBFS and/or FA and/or SF with OPC pastes increases its standard water of consistency an well as setting time, chemically combined water content and bulk density, but decreases the free lime content and the total porosity. The compressive strength of the hardened Portland cement pastes was greatly improved and enhanced at all curing periods particularly with the combination of the three mineral admixtures. The DTA-TG thermo-grams illustrated that a large quantity of CSH and a lower amount of Ca(OH)2 could be formed compared with those of OPC pastes.

Abstract
The influence of the combination of granulated blast furnace slag (GBFS), fly ash (FA) and silica fume (SF) on the characteristics of Ordinary Portland Cement (OPC) pattes was investigated. The results showed that the incorporation of GBFS and/or FA and/or SF with OPC pastes increases its standard water of consistency an well as setting time, chemically combined water content and bulk density, but decreases the free lime content and the total porosity. The compressive strength of the hardened Portland cement pastes was greatly improved and enhanced at all curing periods particularly with the combination of the three mineral admixtures. The DTA-TG thermo-grams illustrated that a large quantity of CSH and a lower amount of Ca(OH)2 could be formed compared with those of OPC pastes.
