Materials used to produce portland cement. Q. What are the raw materials used in the manufacture of portland cement? A. The two principal materials from which portland cement is made are a material of high lime content, such as limestone, chalk, shells, or marl, and a material of high silica and alumina content such as clay, shale, or blast …
Cement is actually a component of concrete. Concrete is made up of four basic components: portland cement, coarse aggregate, fine aggregate (sand), water and admixtures. Ground Granulated Blast Furnace Slag (GGBS), which is a by-product of steel manufacture, is used as a cement substitute in some mixes.
How cement and concrete are made? Cement is the basic element in concrete. It is a delicate powder that serves as the glue that keeps concrete together during mixing with water, sand, and aggregates. Cement is made by burning a precise mixture of finely crushed limestone, clay, and sand in a rotating oven to temperatures …
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement). The three processes of …
