일반 골재와 기포제를 사용한 구조용 경량 콘크리트의 특성에 관한 연구

Abstract

This research is focused on the applying of the foaming agent which can make the independent pore in the concrete structure in order to make a lightweight concrete structure. As a result of the unit volume-weight measurement, when the foaming agent mixed at 0.1% to 0.9%, the lightweight foamed concrete can be applied for the structural member. Also the density and compressive strength measurement results reveals that it will be suitable as structural member with 21MPa strength, when the density is between 1.8~1.9 t/㎥ and foaming agent quantities are 0.6% to 0.9%.
