Reducing the Clinker Factor Part 1 World Cement

The incentive to ‘reduce the clinker factor’ in cement products is two-fold. The primary motivation is to reduce the energy consumption and CO 2 emissions associated with cement clinker production in rotary kilns. It is generally accepted that the production of 1 t of ordinary Portland cement (OPC) creates over 800 kg of CO 2. The secondary

clinker. This clinker is then crushed to a powder. • When limestone is heated, it gives off CO 2. –CaCO 3 CaO + CO 2 • This reaction is unavoidable in the manufacture of cement clinker • So to reduce CO 2 the clinker fraction of cement has to be reduced.

Innovations driving clinker reduction

At present a blended cement (Type 1P) is produced with 20 per cent clinker replacement, but the manufacturer claims full substitution of clinker will be possible once the regulations are revised. Another solution comes from the usage of calcined clays, particularly LC3 (Limestone Calcined Clay Cement), which was considered in detail during a

Cement Clinker Quality Control During Clinker Production

In portland cement manufacturing process, the quality of cement clinker directly affects the quality of the finished product cement.. The following are several important factors affecting the cement clinker quality. In the process of clinker production, strict control of these factors can ensure the production of high-quality, high-yield clinker.

Clinkerization Cement Plant Optimization

Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.

Cement clinker Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Understanding Limestone in Cement| Concrete Construction

Mar 26, 2015· The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding. Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy.

The material is then blended, crushed and fed to the kiln. Post-kiln, the clinker is cooled and goes through a final grinding method before it is ready to ship. Portland cement, the most common type of cement, is formulated in a variety of strengths and colors, depending on its intended use.

Decarbonizing the Cement Industry GCP Applied Technologies

One cement plant in southern Europe used the OPTEVA® CO2ST™ reducer to achieve 4% clinker replacement on top of the 4% they were achieving with their current additive. The 8% clinker replacement was made possible by an increase of strengths of roughly 20 percent at all ages, and a mill output increase of more than 10 percent.
