Belite - Wikipedia

The name was given by Törneborn in 1897 to a crystal identified in microscopic investigation of Portland cement. Belite is a name in common use in the cement industry, but is not a recognised mineral name. It occurs naturally as the mineral larnite, the name being derived from Larne, Northern Ireland, the closest town to Scawt Hill where it was discovered.

Cement - Solex Thermal Sciences

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction.
