摘要：

The effect of mineral additives such as fly ash, slags, limestone, and lime sludge on the hydration of ordinary Portland cement (OPC) has been studied. The samples of OPC with 10 wt% mineral additives were examined separately at 28 and 90 days of hydration by X-ray diffraction and differential thermal analysis. The hydration products in the OPC + slags and OPC + fly ash systems were found to be almost similar to that of purl OPC, except with the low quantity of Ca(OH)(2) during the early period of hydration (28 days). In the case of limestone and lime sludge addition, besides normal hydration phases of OPC, larger amount of Ca(OH)2 and a little calcium carboaluminate hydrates were identified by X-ray diffraction and differential thermal analysis patterns.
