Abstract

Present research compared the effect of chromate reducers such as ferrous sulphate heptahydrate (FeSO4·7H2O) and stannous sulphate dihydrate (SnCl2·2H2O) on the hydration of cement paste, using water‒cement ratio of 0.5 and sealed in plastic bags without curing for 28 days. Uncured hydration properties of cement paste are investigated in detail by thermogravimetric analysis (TGA) and verified with the use of scanning electron microscopy (SEM) and X-ray powder diffractometry (XRD). This research concluded that the cement paste with 0.1% additives showed better hydration in the uncured condition than the control.
