Properties of Cement- Physical & Chemical - Civil Engineering

The heat of hydration is affected most by C 3 S and C 3 A present in cement, and also by water-cement ratio, fineness and curing temperature. The heat of hydration of Portland cement is calculated by determining the difference between the dry and the partially hydrated cement (obtained by comparing these at 7th and 28th days).
