Low heat cement is a special tailored cement which generates low heat of hydration during setting It is manufactured by modifying the chemical composition of normal Portland cement In this article we discuss about the composition, properties, characteristics, uses and advantages of low heat .
Low Heat Cement as the name indicates these type of cement is used inorder to reduce the amount of heat evolved during setting But how the heat evolved during setting can be reduced ? Yes, the heat during setting can be reduced by lowering the percentage of tri-calcium aluminate C3A of about 5% an higher percentage of di-calcium silicate C2S of about 46%

Hydration of cement is an exothermic process that produces large quantity of heat In a mass concrete structure like dams, the rate of dissipation of heat of hydration from the surface is much lower than that generated It causes rise in temperatu.
