What Is a Concrete Grade? The concrete grade is the minimum strength the concrete should hold after 28 days of curing. To understand the acronyms used in the formula, we have broken each element down. M. M stands for the mix of the concrete. So is it a 1-2-3 ratio or a 1-2-4 or a 1-5-10?

This article discusses about the M20 concrete mix, its uses, cement quantity calculation, and more. What is M20 concrete? M20 is a grade of concrete with 20 megapascals (MPa) or 20 Newtons per square millimetre (N/mm^2) compressive strength. M stands for mix, and compressive strength means how much load the concrete can withstand before caving in.

For M 15 grade of concrete mix, the ratio is 1:2:4, which means 1 part cement, 2 part sand, and 4 part aggregate used to prepare concrete mix with water. If you are using M 20 grade of concrete then you have to use a mix ratio of 1:1.5:3. In which 1 is part of cement, 1.5 is part of sand, and 3 is part of cement. Grade of Concrete.

As we find 3.42 bags of cement,768 kgs sand & 1469 kgs aggregate for 1 cubic metre of m7.5 grade of concrete. 225kg of sand and 430 kg aggregate are required per 50 kg bag of cement for m7.5 grade of concrete. Thus, You would need 225kg Sand and 403kg aggregate per 50kg bag of cement to make M7.5 concrete.

Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.

Just as a reminder, it goes as follows: weight = volume × density. For clarity's sake, let's go through a quick example. Let's say we have 15 cubic meters of Portland concrete. The density of this type of concrete in kilograms per cubic meter is 2,300, so the calculation goes as follows: weight of concrete = 15 m³ × 2,300 kg/m³ = …
