If you go for 53-grade cement, you will get a compression strength of 53 mpa (megapascals) in 28 days. 53 grade cement is available in an ordinary mode as well as in special mode. If the initial strength is to be achieved very quickly, it must go for 53 grade cement. The construction pace will be very fast with 53 grade cement.

WPA up to 10% results in better compressive strength than that of the control mix. An improvement of 5.6% & 1.2% was observed, respectively, when compared with the 28- day compressive strength of the control mix. But the compressive strength decreases as the WPA replacement increases over 10%. Maximum compressive strength of 37.89

The paste (cement and water) coats the aggregate (rock, sand) and through hydration the paste hardens, strengthens and creates concrete The key to strong concrete is in the proportions one uses of the three components. Water is the easiest component to over proportion. The more water one uses in the mix the more fluid the mixture becomes.
