2. Medium Grade Concrete (M25 – M35) Medium grade concrete is stronger than standard grade concrete and is used in the construction of foundation walls, columns, and beams. The mix for medium grade concrete is 1:2:4, which means one part of cement is mixed with two parts of fine aggregates and four parts of coarse aggregates.

2020年5月14日 Target strength (Fck) must be greater than the Designated Characteristic strength (fck). The target strength for m20 grade concrete can be found from the formula given in the code book. F ck = = f ck.+1.65s. Standard deviation (S) value for the M25 grade concrete is given in table 1 of IS10262.
MoreS is the standard deviation (for M25 it is 4 as per Table 2) X is the factor based on the grade of concrete (for M25 it is 5.5 as per Table 1) Therefore, the target mean strength is calculated as-f’ck = 25 + 1.65×4 = 31.6 . OR. f’ck = 25 + 5.5 = 30.5. Thus, the mean target strength is 31.6 N/sqmm (higher value of the above two calculations).
