콘크리트 강도증진에 따른 거푸집 존치기간 단축효과에 관한 연구

Abstract

By means of concrete design strength increment, the slab form setting period can be reduced. When the set, construction step could divided as follows; the allowable time of upper story work and the removable time of slab form and support. Six reinforced concrete slabs are loaded and structural behavior and serviceability is observed at each construction step. As results, when the concrete design strength 240kgf/cm' is increased to 350kgf/cma, the slab form can be removed 2 days early without damage of serviceability
