Concrete mix design is required to achieve target strength in structures. Concrete Mix design calculation of M20, M25, M30 grade of concrete with example.

Cement concrete of different qualities or mix are used in the building at different stages according to the type of building. Cement concrete is the most important part of constructional work; it needs special attention during the construction.

Mix proportion for M25 grade of concrete is 1:1:2(cement:fine aggregates:coarse aggregates).So if you need 4cu.m of M25 concrete, we need to have 1cu.m of cement. So, theoretically, for 1cu.m of M25 concrete, we need to have 0.25cu.m of cement.

Quantity of Water is added in M20 grade concrete (All grades):-As I already given detailed explanation about how to find out the quantity of Cement, Sand and Aggregate required for different grades of concrete. Here you can learn about quantity of Water is added in M20 grade concrete (all grades).

Grades of Concrete with Proportion (Mix Ratio) We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting.

Following is a simple method used by engineers to calculate cement, sand and aggregate to produce different grade of concrete like M5, M7.5, M10, M15 and M20. if you don't want to learn the math involved in the design, you can use the table given at the end of the article to produce different grade of concrete.

the required grade of concrete is M25 ie, 1:1:2 assuming the thickness of roof slab is 150 mm(.5 feet) area of slab = 100 square feet therefore volume of slab = 100 x thickness = 100 x .5 = 50 cubic feet or volume of slab in meter cube = 1.42 cubi...

Calculation of Quantities of Cement, Sand and Aggregate in 1m 3 of concrete:-. To calculate the individual quantities of cement, sand and aggregate required for 1m 3 assume a nominal mix grade of concrete such as M20. You can use same method to calculate any grade of concrete.

Following are the information required for concrete mix design: 1. Characteristic strength of concrete required: Characteristic strength is the strength of concrete below which not more than 5% of test results of samples are expected to fall. This can also be called as the grade of concrete required for mix design.

The sand which is used in mortar can be natural sand, or crushed stone sand or crushed gravel sand. Sand or fine aggregate which is used in concrete is somewhat different from sand which is used for masonry mortar. The role of sand in mortar is to give the following properties such …
