Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc'. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.

When most contractors think about concrete mix design—if they think about it at all—the first thing that comes to mind is "bags" or "sacks." In the old days, when most concrete was mixed on site, cement was purchased in bags. A bag is 94 pounds of cement, or about 1 cubic foot; but if you order a 6-sack mix, all that tells you is how much portland cement is in the mix. That mix could be ...

Grade Of Concrete. Concrete is generally graded according to its compressive strength as per IS-156,2000 there are fifteen grades (M10 to M80) of concrete in the designation of concrete mix, the letter M refers to the concrete mix and the number refers to the specified characteristic strength of concrete at 28 days expressed in MPa.. The grade M10, M15, M20 are term as ordinary concrete.

Design mix concrete is preferred to nominal mix. If design mix concrete cannot be used for any reason on the work for grades of M-20 or lower, nominal mixes may be used with the permission of engineer-charge, which however is likely to involve a higher cement -in content. Accordingly all concrete of above M-20 Grade for RCC work must be of design mixes. The code allows nominal mix for RCC …
