The cement, which is generally used for preparing concrete, is the Ordinary Portland Cement. But for special purposes other qualities of cement such as Low Heat Cement, Rapid Hardening Cement, High Alumina Cement, White Cement, Blast Furnace Slag Cement, Sulphate Resisting Cement, etc. .
The main objective is to assess the impact of parameters such as cement color and pigment dosage on mechanical properties and color stability. Concrete specimens were made using grey and white cements and three different dosages of red, yellow and green pigments.
Portland Cement Manufacturing Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these

Dec 03, 2016· 4. White Cement: White cement is a type of ordinary Portland Cement which is pure white in color and has practically the same composition and same strength as OPC. To obtain the white color the iron oxide content is considerably reduced. The raw materials used in this cement .
Types of cement. Cement is a binding material used to bind different type of construction materials together. It is formed from argillaceous, siliceous, calcareous etc. By twisting this internal mix ratio and by altering the chemical inputs, special types of cement can be produced according to the needs.
White Portland cement or white ordinary Portland cement (WOPC) is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness. Obtaining this color requires substantial modification to the method of manufacture, and because of this, it .
