All over the world, cement is one of the most important building materials Whether for houses, bridges or tunnels, we cannot imagine our modern world without it Join us for a short tour to experience how cement is made: starting with the extraction of raw materials and ending with the finished product
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together There are two main forms of cement: Geopolymer cement and Portland CementCement is seldom used on its own, but rather to bind sand and gravel togetherCement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete
HYDRATION OF CEMENT It is the reaction (s eries of chemical reactions) of cement with water to form the binding material In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass -the hydrated cement ,
wet process was mostly preferred because the homogenization of wet raw materials was easier than that of dry powders The wet process also enables an easier control of the chemical composition of the raw mix However, the wet process is more energy intensive and Fig 1 - Simplified cement production process, Contact Supplier

What Are the Differences Between the Wet and Dry Processes of a Cement Manufacturer? The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay or iron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln .
chemical composition (US EPA)  Figure 1 shows part of a cement making factory in Zimbabwe Figure 1: Cement Production Plant (Cement Company, Zimbabwe) After the mining, grinding and homogenization of raw materials, the process of calcination is followed by burning the resulting calcium oxide together with silica, alumina and ferrous
