If the form of concrete is removed at the time elapsed three or four hours after placing and if the concrete dried by the wind or the sun exposure as in summer, the required strength will not be expected, because of hydration of cement needs water. In recent period, the removal of form tends to be in very early period as in slip-form construction, the precast concrete member and concrete of column or wall placing in site. In this paper the effects of stripping form at very early age on the strength of concrete are studied by verying curing temperature, curing humidity and period of keeping form of concrete.
