Abstract
Objective of this study is to identify properties on strength increase of hardened concrete and fluidization of non-hardened concrete using waste ceramics generated by construction waste, which is a type of industrial waste, and by ceramics, which is a clay plastic, during its production process, and determine length change ratio caused by drying shrinkage during substitution of recycle aggregate and waste ceramics, and whether they can be used as concrete compounds. Slump of non-hardened concrete exhibited the best fluidization and formability at recycled aggregate's replacement ratio of 60% driven by higher substitution ratio of recycled aggregate and waste ceramics while air content met the KS requirement when substitution ratio of waste ceramics was
본 연구의 목적은 폐도자기 분말도 변화에 따른 순환골재 강도 증진에 관한 연구로 유동성은 폐도자기 분말 치환율이 증가할수록 유동성이 감소하는 경향으로 나타났으며, 공기량은 KS 한도범위를 만족하는 것으로 나타났다. 압축강도는 순환골재 및 폐도자기 분말 치환율이 증가할수록 증가경향이고, 내구성으로 건조수축에 의한 길이변화는 폐도자기 미분말이 커질수록 다소 완만한 건조수축율을 나타내었고, 또한 단열온도상승은 순환골재 대체율 및 폐도자기 미분말이 증가할수록 최고온도에서 약
