contact usExample Calculation. Average Strength μ = 744/30 = 24.8 N/Sqmm. n = Number of sample. Std Deviation = √[274.8 (n1)] = √(274.8/29) = 3.07 N/sqmm. Hence the Standard Deviation of above concrete cube test results – 3.07 N/Sqmm. As per IS 456, the assumed standard deviation value has mentioned from past records for a similar grade of concrete.
