Cement Manufacturing Process Phase IV Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here raw material is heated up to 1450 C. This temperature begins a chemical reaction so called decarbonation. In this reaction material
Proportioning of materials. Portland cements can be modified easily depending on the raw materials used and the process used to combine them. Proportioning of the raw materials is based on a series of simultaneous calculations that take into consideration the chemical composition of the raw materials and the type of cement to be produced American Society for Testing and Materials ASTM Type

Through a chemical reaction called hydration the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete. The strength of the paste in turn depends on the ratio of water to cement. The watercement ratio is the weight of the mixing water divided by the weight of the cement.
