Contrete reaches its full strength in 28 days. Then, why
are we removing shutter in 7/ 14 days?

Answer Posted / v.kapil

Concrete get its 50 % strength in 3 days and 66.6% in 7 days
with OPC grade of cement, we designed our structure for
full load including of factor of safety but actually such
loads never come structure in its whole life span, only 40-
50% loads ware accoured during construction so we can
remove our form work after 7-10 days but after confirmation
of cube results of 7 days.
