Abstract
클링커 대신 고로슬래그, 폐인산석고, 폐석회 등의 산업 부산물을 이용하여 비소성시멘트를 제조하면 산업부산물 재활용, 클링커 제조를 위한 에너지 감소, <TEX>$CO_2$</TEX>저감으로 인한 환경오염문제 및 생산원가 저감 등의 장점이 있다. 이러한 이유로 본 연구에서는 비소성 시멘트 콘크리트의 역학적 거동실험을 수행하여 비소성 시멘트 콘크리트의 탄성계수, 응력-변형률 관계를 제안하였다. 또한 철근비, 압축강도를 변수로 9개의 구조 시험체를 제작하였으며, 그 실험 결과 비소성 시멘트 콘크리트의 휨 및 전단 거동 경향은 일반 콘크리트 부재와 크게 차이나지 않는 것으로 나타났다. If cement could be manufactured with industrial byproducts such as granulated blast furnace slag, phosphogypsum, and waste lime rather than clinker, there would be many advantages, including the maximization of the use of these industrial byproducts for high value-added resources, the conservation of natural resources and energy by omitting the use of clinker, the minimization of environmental pollution problems caused by <TEX>$CO_2$</TEX> discharge, and the reduction of the production cost. For this reason, in this study, mechanical behavior tests of non-sintered cement concrete were performed, and elasticity modulus and stress-strain relationship of non-sintered cement concrete were proposed. Nine test members were manufactured and tested according to reinforcement ratio and concrete compressive strength. According to the test results, there was no difference between general cement concrete and non-sintered cement concrete in terms of flexure and shear behavior.
