Strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton's per millimeter Cubic') compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are …
3. Aggregate: Aggregate refers to coarse and fine materials such as gravel, crushed stone, and sand used in concrete. The amount of aggregate required for 1m3 of M20 concrete is calculated by multiplying the volume of concrete by the ratio of aggregate to concrete. This ratio is 3/5 x 1 = 0.6 m3 of aggregate.
M20 has a compressive strength that gets added up to 28 days. PROPERTIES OF THE M20 GRADE CONCRETE: The M20 Grade Concrete comes in a mix ratio of 1:1.5:3.1 cement.1.5 sand and three aggregate.

Volume of aggregate = (M20 aggregate proportion / sum of M20 ratio) × Dry volume = ( 3 / 5.5 ) × 1.54 = 0.84 m³. Weight of aggregate = Volume × Density (Density of aggregate = 1550 kg/m³) = 0.84 × 1550 = 1302 kg. Similarly, approximately 1.3 metric tonne of aggregate will be required for 1 cubic metre of M20 concrete.
