avg strength of concrete is 20 N/mm2 i,e, 95% of the tested ones gives 20n/mm2

Required slump height of M20 for different concrete structures, are normally calculated by the required slump value, which would come out to be 100 lits.

it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....
