crushing value for ordinary concrete

The cube tests give much greater values of crushing strength, usually 20 to 30 % more than those given by cylinders. ... Tests have shown that for concrete made with ordinary Portland cement the ratio of the 28 days to 7 days’ strength generally lies between 1.3 to 1.7, and the majority of the results fall above 1.5.
