Cement - Extraction and processing Britannica

Cement - Cement - Extraction and processing: materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones slates and some shales with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators. The excavated materials are transported ...


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 material; therefore for the cement production the mix is selected for the following

How Cement Is Made

These ingredients when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement. Bricklayer Joseph Aspdin of Leeds England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove.
