A Study on the Pore Structure of Recycled Aggregates Made of EPS Waste and Insulation Performance of Lightweight Concrete
폐 EPS 재생골재의 공극구조와 경량골재큰크리트의 단열성능에 관한 연구
Abstract
This study is to investigate the insulation performance of lightweight concrete using recycled lightweight aggregate, to develop lightweight concrete products which have an excellence on the insulation performance are satisfied with properties of building materials. As a result of this study, recycled EPS aggregate is considered to have an independent pores which is closed by dense partitions. So, it is showed that the insulation performance of lightweight concrete using recycled EPS aggregate are excellent. Especially, in the case of lightweight concrete under conditions of replacement ratio over 100%, it is considered that insulation performance is very excellent as thermal conductivity is showed about 0.2kcal/mh
