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.

The UK cement industry has agreed to reduce its primary energy consumption by % per tonne of cement produced by 2010, from a 1990 baseline. In return, the industry receives an 80% rebate from the Climate Change Levy. The reductions are phased over a number of years (Table ) MINERAL PROFILE: CEMENT RAW MATERIALS 2: Extraction and processing
Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. According to some estimates, around 180250 kg of coal and about tonne of limestone is required to produce a tonne of cement.
