Concrete grades are denoted by M10, M20, M30 according to their compressive strength. The "M" denotes Mix design of concrete followed by the compressive strength number in N/mm 2 "Mix" is the respective ingredient proportions which are Cement: Sand: Aggregate Or Cement: Fine Aggregate: Coarse Aggregate. we already discussed the mix

Previously the specification for concrete was proportion of Cement, Sand and Course Aggregates. The fixed ratio of these was to ensure the strength to the structure. Nominal concrete mix are low grade concrete mixes which are used for small and unimportant works. In this method, fine aggregate quantity is fixed irrespective of cement and coarse aggregate proportions. Hence, the quality of

Specific gravities of concrete materials are as follows: Cement = Sand = Coarse aggregates = The percentage of entrained air assumed is 2%. The mix proportion of 1::3 by dry volume of materials can be expressed in terms of masses as: Cement = 1 x 1500 = 1500. Sand = x 1700 = 2550. Coarse aggregate = 3 x 1650 = 4950.

Concrete is a mixture of cement, sand (fine aggregate), small stone or gravel (coarse aggregate) and water. It has many applications, from fence posts to motorway bases and, because of this, there are many different concrete mix ratios that the constituents can be mixed to with each resulting in a different strength of concrete.

It is the process of determination or selection of the relative proportion of concrete ingredients that means cement, sand, coarse aggregate, and water to obtain concrete of desired quality.. From the strength point of view and economy, the main objective to select the fine and coarse aggregate in such a ratio to get a dense mix with minimum voids using the least amount of cement.
