Rapid hardening cement is very similar to ordinary Portland cement OPC. The early strength is achieved by adding excessive C3S in the mix and by lowering the C2S content in the cement. As the name itself resembling that, this type of cement is used where there is a need for high early strength. Ex. Pavements, busiest roadways The strength of Rapid Hardening cement at age of 3 days is almost same as the 7 days strength of Ordinary Portland cement. It requires same water-cement ratio as OPC.
