What Is Grade of Concrete & Its Ratio for Mix

What Is the Grade of Concrete?

Grades of concrete are defined by the concrete mix proportion and the minimum strength of concrete at end of 28 days curing period. The Concrete Grade is can be known by calculating the compressive strength of concrete in Mpa, where M stands for mix and the MPa denotes the overall strength There are different types of concrete mix which are based on concrete classification according to its compressive strength. For making concrete we use cement, sand, aggregate, and water which are mixed with a certain ratio, and concrete is cast and put in a cube of 150 mm size and put in a water bath for 28 days and afterward, it is tested in a compression testing machine. The compressive stress result is known as the “grade of concrete". It is expressed in N/mm² The concrete grade is denoted by M10, M20, M30, and so on according to their compressive strength.

Concrete Grade As Per Indian Standards

The “M” refers to Mix and Number after M (M10, M20) Indicating the compressive strength of concrete after 28 days of curing and testing. M indicates the proportion of materials like Cement: Sand: Aggregate (1:2:4) or Cement: Fine Aggregate: Coarse Aggregate. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days. In the designation of concrete mix M  to the mix and the number to the specified compressive strength of 150 mm size cube at 28 days, expressed in N/mm^2.

Concrete Grade Per British/European standards

As per  BS 8500-2 British/European standards, the grade of concrete is denoted as C10, C15, C20, C25, etc., ‘C’ which means ‘Concrete Strength class’, and the number behind C refers to characteristic Compressive strength of Concrete in N/mm2 @ 28 days when tested with the 15 cm dia. & 30 cm height cylinder in a direct compression test.

The grade of concrete is also denoted as C16/20, C20/25, C25/30, etc., which means Concrete Strength Class (C) the number behind C refers to the Compressive strength of Concrete in N/mm2 when tested with Cylinder / Cube. Different mix proportions of the materials used to make concrete namely - Cement - Coarse aggregate - Fine aggregate - Water Resulting in concretes with different properties.

To make M 30 grade of concrete, we have to prepare a mix design for it as per IS Code. In M 30, M is for Mix, and 30 is the design compressive strength of concrete, You May Also Like - What is RCC - Reinforced Cement Concrete - Concrete Mix Ratio | Concrete Ratio | Concrete Proportions | Concrete Mix Ratio Table | Concrete Grade Ratio | Concrete Mix Design Ratio - How Many Bags of Concrete Do I Need For 10×10 Slab - How Many Bags Of Concrete In A Yard | How Many Bags of Concrete Do I Need - What Is Plain Cement Concrete (PCC) – Materials, Uses & Grades - Concrete Mix Design | Concrete Mix Design Calculations pdf | Concrete Mix Design Excel Sheet | IS 10262 Code 2019 pdf Download | Mix Design Code - Site Mix Concrete Vs Ready Mix Concrete – Which is Better - Mix Design of Concrete For M20, M25, and M30 With Procedure Read the full article
