INFORMATION ON LAFARGE Cement Products

Cement is made by crushing and grinding calcium carbonate (limestone), silica (sand), alumina and iron ore in appropriate propor-tions and heating the resulting mixture in a kiln to approximately 1,500C. In the more modern "dry process" used by around 80% of our plants, the ore mixture enters the kiln dry as opposed to the older process in

Cement Kilns: Precalciner kilns

This optimisation of thermal efficiency allows a large output to be produced by a relatively small kiln. The kiln solely performs the sintering process, for which the rolling action of the rotary kiln is indispensible. A number of distinct advantages of air-separate precalciners has resulted in their almost universal use in modern cement plants.

A History of Cement

Portland cement today, as in Aspdin's day, is a predetermined and carefully proportioned chemical combination of calcium, silicon, iron, and aluminum. Natural cement gave way to portland cement, which is a predictable, known product of consistently high quality. Today, about 98 percent of the cement produced in the United States is portland cement.
