as m20 is specification .as we know compressive strength of
M20 after curing will be 20kn/m2.but after 7 days it will
gain 60% strength..........

compressive strength of concrete for 21 day curing period
is 21 MPa whic is equal to :
= 2,100 N / mm2
= 2.10 KN / mm2
for a 7 day curing period, strength will be 1/3 of the
comp.stregth.
