It depends on the mix used if it is M10 compressive
strength in 28 days will be 100Kg/cmsq.If it is M30
compressive strength in 28 days will be 300 kg/cmsq.

Answer / biswas deb narayan

Hence compressive strength of concrete is the strength of
concrete which it can wistend under compression.

Answer / anand kumar

compressive strength of concrete is strength of material
below which not more than 5% of test result are expected to
fall.

Answer / fazil

The compressive strength of concrete is the most common
performance measure used by the engineering in designing
buildings and other structures.
The compressive strength is measured by breaking the cubic
concrete specimen in CTM(compression testing machine).
The compressive strength is calculated from the failure load
by the cross sectional area resisting the load And reported
its units in KN.
(i.e) Fc = max load of the cubic specimen / area of the cube

where Fc - comp.strength of concrete in KN

Answer / silpa

strength of concrete = Pressure/Area,

Eg: 475*1000/150*150=21.11N/mm2.
