The equivalent cube strength of the concrete shall be determined by multiplying the corrected cylinder strength by 5/4.

MoreHow is compressive strength measured? The compressive strength of concrete is often tested to evaluate if the actual concrete mix meets the requirements of the design specification. The test is usually conducted in batching laboratories. In order to conduct the compressive strength test, a small sample of concrete mix is first cast in a cube or

More15 cm cube strength after 28 days of curing is compressive strength. Also only 5% results are expected to fail and 95% results indicate the compressive strength of particular grade of concrete.

MoreCompressive strength of cube ( 150 x 150 x 150) is higher than that of cylinder (150 x 300). Length of these two are not same. Buckling may be a factor for cylinder strength. But while considering section we assume of same length for both circular and rectangular column.

MoreConcrete strength measured using concrete cubes produce results different than concrete cylinders. Conservative estimates put concrete cylinders at 80% of concrete cubes, for high-strength concrete some say the percentage is near 100%. The ratio between the cube(150mm) and cylindrical sample(150×300 mm).
