Concrete Mix Design. Concrete mix design is often mistakenly referred to as "cement mix design." However, cement is simply one of the ingredients of concrete. It is a binding substance that allows concrete to set, harden, and adhere to other materials. Therefore, it cannot and should not be used interchangeably with concrete mix design.
Shear design of rectangular beam Shear design include estimation of stirrup spacing to support ultimate shear. Commonly, part of concrete will resist shear force but the portion of which is not supported by concrete will be carried by shear reinforcement. Firstly, compute ultimate shear force at distance d which is the depth the cross section.

To calculate the amount of water required for a concrete mix, we need to calculate the quantity of cement required. Assume the required amount of cement is 50kg. Amount of water required = W/C ratio x cement required. = 0.5 x 50 = 25 litres/50kg. For the design mix, W/C ratio depends upon the workability and strength requirements.
The design of reinforced concrete water tank is based on IS 3370: 2009 (Parts I – IV). The design depends on the location of tanks, i.e. overhead, on ground or underground water tanks. The tanks can be made in different shapes usually circular and rectangular shapes are mostly used. The tanks can be made of reinforced concrete or even of steel.
