CEMENT RAW MATERIALSconcrete to be placed and compacted before hardening commences. Blended cements are produced by intergrinding cement clinker with materials like fly ash, granulated blastfurnace slag, limestone dust, natural (eg. volcanic ash) or artificial (eg. metakaolin) pozzolanas, in addition to gypsum/anhydrite. The finished cement is transported in bulk or

Role of Gypsum in Cement and its EffectsRole of Gypsum in Cement. The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water. The process involved in hydration of cement is that, when the water is added into cement, it starts reacting with the C3A and hardens. The time taken in this process is very less, which doesn't ...
