Abstract
Ordinary Portland Cement produced by one of the S.C.C.P. units, is the subject of hydration studies, using thermal methods such as TG and DTA. Hydration is measured in terms of hydration product formation and the amount of chemically bound water and free calcium hydroxide contained in the hydration products for different curing times. i in ' t > It is noticed that the critical degree of hydration at which strength starts developing, is a function of hydrating time and theoretically corresponds to the termination of acceleration period, when tri-calcium and di-calcium silicates in the cement have hydated, to produce enough hydration products to intermesh and initiate an early strength. The experimental data is interpreted in terms of strength development as a function of hydration.
