Answer Posted / santhosh kumar
basically deshuttering of slab is in depend up on the mix
propotion of the concrete.and achived strength more than
75%.
like m15 is needed for deshuttering period is 21 days
we are using m20,for slabs need 14 days is enough.
in beams we are using m20 and above 10 ~14 days are
applicable in practcial.
for using post tension in the slab we are using m35
concrete in slabs it is deshutttered 7 ~ 8 days.(when the
portion is after stressed)
to calculate the concrete strength in lab take 3 cube of
concrete and tested in lab 3 cube average strength is
needed 75%.
