Reading time 1 minute Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 124 means that cement, fine and coarse aggregate are in the ratio 124 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
Feb 25, 2020 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.
Let us be clearer with an example of M25 grade concrete mix ratio. The proportions of cement in M25 grade of concrete is as follows- 1 part of cement, 1 part of sand or fine aggregates, 2 parts of coarse aggregates, and Required quantity of water. Mixing the cement, sand aggregates in the following proportions will result in M25 grade concrete.
