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.

Concrete Proportion and Concrete Mixture Ratio The two different ways in Concrete Proportioning Mixture: 1. Volume Method 2. by Using Mixturing Box. Volume Method is the most common and convenient method in Mixing Concrete to attained the desired strength of concrete.Concrete misture, it involves cement, sand and gravel.

2. Standard Mix Concrete Ratio. Nominal admixtures of fixed cement-aggregate ratios (by volume) vary widely in strength and may result in more or less rich admixtures. For this reason, minimum compressive strength is included in many specifications. These mixtures are called standard mixtures.. IS 456-2000 designates concrete mixes in several grades as M10, M15, M20, M25, M30, M35, and M40.

The concrete mix ratio is usually represented by the quality of various materials per cubic meter of concrete, or amount proportion of various materials. The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete.

Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need. To make concrete there are four basic materials you need: Portland cement - …
