CEMENT CONCRETE MIX DESIGN - Dronacharya

The various factors affecting the mix design are: 1. Compressive strength It is one of the most important properties of concrete and influences many other describable properties of the hardened concrete. The mean compressive strength required at a specific age, usually 28 days, determines the nominal water-cement ratio of the mix. The other

Portland Cement Flexural Strength - Pavement Interactive

Flexural strength (sometimes called the modulus of rupture) is actually a measure of tensile strength in bending. PCC flexural strength testing is carried out on a 40 x 40 x 160 mm (1.57-inch x 1.57-inch x 6.30-inch) cement mortar beam. The beam is then loaded at its center point until failure.

Calculate cement sand aggregate for concrete | Nominal Mix ...

I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand. Too much sand causes shrinkage and this will not give high-density concrete. Hence use 1:2:3 for good strength and 1:2.5:3.5 for moderate strength.
