properties. In the U.S., the different varieties of cement are denoted per the American Society for Testing and Materials (ASTM) Specification C-150. Cement is produced from raw materials such as limestone, chalk, shale, clay, and sand. These raw materials are quarried, crushed, finely ground, and blended to the correct chemical composition.

The crushed raw ingredients are made ready for the cement making process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture. The composition of cement is proportioned here depending on the desired properties of the cement. Generally, limestone is 80% and remaining 20% is the clay.

affected. In particular, cement production in Spain decreased by 23% in 2008 relative to 2007.1 Due to this huge drop and the forecast for the coming years, cement producers feel obliged to take measures to drastically reduce production costs. One of the fields most affected by these cost-reducing measures is the grinding aids sector, which has ...
