can you please explain us about what are the minimum thicknesses for pcc in proportions for all the civil works i,e from raft to finishing of a building?
I am not sure what your are referring as PCC. As per my knowledge it is a Plain cement concrete, which is a bed layer used to laid on the ground. Over that foundation will be rested. Usually it will be 10cm thick.prahumaccivil works i,e from raft to finishi
The PCC is mainly laid to provide a rigid impervious layer for to RCC over the excavated area before any masonry works set in. PCC minimum thickness should be 300 mm and 600mm in deep excavations. In any case it is advisable that the thickness should not exceed 1500mm.
