Substitution of clinker in cement is an example of the positive contribution of the European cement industry to resource management.These include the chemical composition of the final product (cement) as well as the environmental impact of the cement production process.

Portland cement clinker Understanding Cement

Portland cement clinker - overview. 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.

What are Cement Clinkers with pictures

Cement powder is commonly made of lime and clay and is a key ingredient of concrete. Natural raw materials can be utilized in a kiln to form cement clinkers, although other materials with the proper chemical composition are also used, such as fly ash from coal …
