Feb 25, 2020 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.

M25 grade concrete ratio is 112 mixture of cement, fine aggregates and course aggregate in which one part is cement, one part is sand and two part is aggregate. The degree of preparation of the concrete is selected based on the m25 grade concrete mix design. There are two types of m25 concrete ratio concrete mixes, nominal mix and design mix.
May 17, 2017 Concrete Mix design of M5, M7.5, M10, M15, M20, M25, M30 and higher grades of concrete is calculated as below The procedure for finding the different grades of concrete mixes are same. The below mentioned method can be applied to any grade of concrete by changing the values. To make ease in understanding we are finding the Concrete mix design ...
