Portland cement clinker

Portland cement clinker

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

The decarbonation of limestone to give the calcium required to form silicates and aluminates in clinker releases roughly 0.53 t CO 2 per ton of clinker [8]. In 2005, cement production (total cementitious sales including ordinary Portland cement (OPC) and OPC blends) had an average emission intensity of 0.89 with a range of 0.65–0.92 t CO 2 .

Limestone is the pre-requisite to make Clinker. Limestone is extracted from Mines. A company that has its own mines is at an advantageous position than the one which doesn’t have mines. Limestone cannot be traded, so a company which has no mines cannot make clinker. However limestone is a natural resource and more than 65% of India’s .

How is concrete made from limestone? | Shelly Company

 · To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.
