Present research compared the effect of chromate reducers such as ferrous sulphate heptahydrate (FeSO4 center dot 7H(2)O) and stannous sulphate dihydrate (SnCl2 center dot 2H(2)O) on the hydration of cement paste, using wateraEuro'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.
