RAW MATERIALS IN CEMENT PRODUCTION

07/02/2019  The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components: CARBONATE COMPONENT (rich in calx) is contained in the raw mix in a quantity of 76-80%: Limestone.

Environmental impact of concrete - Wikipedia

Carbon dioxide emissions and climate change. The cement industry is one of the two largest producers of carbon dioxide (CO 2), creating up to 8% of worldwide man-made emissions of this gas, of which 50% is from the chemical process and 40% from burning fuel. The CO 2 produced for the manufacture of structural concrete (using ~14% cement) is estimated at 410 kg/m 3 (~180 kg/tonne @ density of 2 ...

Cement Concrete - Portland Cement Association

Cement Concrete. In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
