Once a RCC roof Slab is casted, can we make wall next day. Will vibration make slab weak. After how many days we can make wall or erect column on a newly casted slab.
Dear Panchal
After intial setting of cement concrete i. e. after 24 hours, we can start erecting of columns wall but care should be taken that every material wanted should be placed gentely on the top of slab after doing proper curing of the slab before starting the work. Also take care that curing must be regularely.
