Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. 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.
· Different Grades of Concrete explained … Different projects often require different grades of concrete. In this instance, t he g rade is defined as the strength and composition of the concrete based on the minimum strength the concrete needs to be after 28 days following initial construction.. C Grade concretes are measured using cubic concrete testing.

The cement contents were 350 kg/m3 and 450 kg/m3 for the C20/25 and C30/37 classes, respectively. Recycled aggregate concrete was made with
Understanding Grades of Concrete. Based on the strength and composition of the concrete, the grades of concrete are set. After completion of 28 days of preliminary construction, the concrete attains it''s least strength. The grade of concrete is calculated with measuring unit MPa, where M signifies for mix and the MPa for the complete strength.

In the concrete compositions, 360 kg/m 3 PC-A cement was used; the maximum grain size of the river gravel was 31.5 mm. Because a major objective was to realise highly fluid mixtures, the fresh concrete slumps were 230 plus-minus 40 mm. This resulted in a water to cement ratio of 0.32 for the mixtures containing fillers and 0.35 for the reference mixture (no filler added).
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/mm2.
