Cement, but is also influenced by water-cement ratio, fineness and curing temperature. as each one of these factors is increased, heat of hydration increases. for usual range of portland cements, about one-half of the total heat is liberated between 1 and 3 days, about three-quarters in 7 days, and nearly 90 percent in 6 months.Cement : manufacture chemical composition heat of Hydration of portland cement. introduction portland cement is a hydraulic cement, hence it derives its strength from chemical reactions between the cement and water. the process is known as hydration. cement consists of the following major compounds see composition of cementgrinding mill.

Apr 23, 2017 the process of manufacture is very simple, and, in brief, is as follows:—. the dried granulated slag is mixed with a predetermined quantity of dry slaked lime and ground to an impalpable powder. it is then ready for use as cement. the slag sand, after being drained, still contains a large percentage of adhering water.
