CLINKER GRINDING IN CEMENT PRODUCTION

Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

Clinker: compositional parameters - Understanding

Clinker: compositional parameters. Chemical parameters based on the oxide composition are very useful in describing clinker characteristics. The following parameters are widely used (chemical formulae represent weight percentages): Lime Saturation Factor (LSF) The Lime Saturation Factor is a ratio of CaO to the other three main oxides.

Properties and behavior of limestone cement concrete

2000-10-1  In this paper, the properties and the behavior of limestone cement concrete and mortar are studied. Portland limestone cements of different fineness and limestone content have been produced by intergrinding clinker, gypsum and limestone. In order to have compatible results, the produced cements were selected to have the same level of strength.
