ST1 – Concrete A low strength (lean mix) ST1 concrete for general 6 units of mm gravel, with 3 units of a grit sand and 1 unit of ordinary »More detailed/5. Application of Different Types of Cement Rapid Hardening Portland Cements Rapid hardening versions of CEM I cements are available. The average particle size is smaller in these cements and they gain strength more quickly than do ordinary CEM I types. They generate more heat in the early stages and can be useful in cold weather concreting.

Division on setting time of cement is based on Initial setting time of cement and Final setting time of cement. Generally Initial setting is the time elapsed between the moment water is added to the cement to the time at which paste starts losing.

1. RAPID HARDENING CEMENT: Rapid hardening cement is very similar to ordinary portland cement (OPC). It contains higher c3s content and finer grinding. Therefore it gives greater strength development at an early stage than OPC.

The strength of this cement at the age of 3 days is almost same as the 7 days strength of OPC with the same water.The cement shall be ordinary Portland cement, or rapid hardening Portland cement complying in all respects with the requirements of B.S. 12, “Sulphate Resisting Cement”, shall comply with B.S.
