Jhanwar added: "With an annual supply of 1.2 Mt of red mud from Hindalco, we expect to conserve more than 1 Mt of mined natural resources like laterite in our manufacturing process. Enhancing our …

laterite for brick production is economical because little cement is required. Also, when compared with fired clay bricks, the production of laterite bricks does not involve the firing process. Several researchers have reported that cement-stabilised laterite can be used in building and road construction (Folagbade, 1998; Agbede and Manasseh,

Cement - Extraction, Processing, Manufacturing: Raw 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 …

How cement is made. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
