research delivers SiloSafe cement. Cement produced at low mill temperatures (app. 7580 degrees Celsius) had a relatively low level of gypsum dehydration com­ pared to typical mill cement. However as the cement temperature is low the gypsum in the silo does not dehydrate. Thus making the cement SiloSafe.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln. ...

This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o F to 2,600 o F). It hydrates rapidly, but does not contribute much to strength of the cement paste. By mixing these compounds appropriately, manufacturers can produce different types of cement to suit several construction environments.

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
