본 연구에서는 폐콘크리트 미분말을 이용한 재생시멘트의 화학조성 및 응결시간 등 시멘트로서 요구되는 기초적인 물성과 강도 및 유동성능의 개선을 목적으로 소성시간과 방법에 초점을 맞추어 실험적으로 고찰함으로써 보다 합리적인 재생시멘트의 제조방법을 구축하고자 한다. |

Recently, the study to reduce and recycle industrial waste is underway vigorously in the various fields of industry according to the conservation of environment and resources. In construction work, the disposal problem of its waste and environmental disruption have already been serious all over the world. However the recycle of waste concrete is still at an early stage, recycled aggregate from waste concrete have only used those as subsidiary road fillers. The research institute and the company make the study that it is about the properties of recycled aggregate and those structural capacity since 1990. Through the experimentation last year, we know that strength and fluidity of recycle cement are inferior to normal cement, and admixing aggregate powder deteriorates its strength. The purpose of this study is to search for appropriate heating time and to improve performance of the recycle cement while heating hardened cement which is crushed, we investigate separating aggregate from hardened cement by preheating and improvement of strength and fluidity in recycle cement which contains admixture. |
