~ Concrete is the homogeneous mixture of cement or lime, sand, aggregate and water in a fixed proportion. Its quality plays a vital role in the strength and durability of the structure. Hence, the quality of concrete is expressed as grades of concrete. Higher the grade of concrete; higher will be the quality and vice versa. ~ The grade of concrete is the minimum strength that the quality ...

F'ck = fck + factor based on grade mix design for M25 concrete, whichever is higher For M25 grade concrete Factor based on grade of concrete = 5.50 Standard Deviation = 4.00 F'ck= 25 + 1.65 X 4 = 31.60 N/mm2 F'ck = 25 + 5.5 = 30.50 N/mm2. Hence higher value of F'ck = 31.60 N/mm2 is to be used for design calculations

The "M" refers Mix and Number after M (M10, M20) Indicates 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.
