Low Heat Cement Manufacturing Low Heat Portland Cement
Low heat cement is also known as low heat Portland cement, code number PLH. It is a type of hydraulic binding material made by mixing and grinding together ordinary Portland cement clinker, an appropriate amount of gypsum, and other admixtures. As its name indicates, low heat cement releases low heat of hydration.

Its rate of heat development also is very high. Its rate of heat development is 9 calories/hour per gram of cement (9 cal/g/h), whereas for rapid hardening cement, rate of heat development is (3.5 cal/g/h) i.e., it is 2½ times that of rapid hardening Portland cement. However total heat of hydration is of the same order for both the cements.
