Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete. the advantages of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving required strength of structural members.
Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength of concrete. for example, if the concrete mix ratio of m20 concrete is 11.53, then 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume should be batched to prepare m20 grade concrete.
Note 1 the above recommended mix design must be verified, by actual cube tests. 2 the mix design is based on the quality and grading of the materials actually supplied, by the client. any variation in quality and gradation will result in changes in the mix design. this mix design was submitted by a regular contributor to this site.
The common method of expressing the proportions of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine 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

Dec 08, 2017nbsp018332mix represents concrete with designated proportions of cement, sand and aggregate. and the number following m represents compressive strength of that concrete mix in nmm 2 after 28 days. for example, for m20 grade of concrete mix, its compressive strength after 28
May 17, 2017nbsp018332to make ease in understanding we are finding the concrete mix design of m20 grade concrete. the concrete mix ratio for m20 grade of concrete is 11.53 that mean 1 part of cement, 1.5 part of sand fine aggregate and 3 parts of aggregate crushed stone in volume and then batched for mixing. to know the concrete mix design follow below
A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens.
