Lightweight aggregate concrete (LWAC) shows a smaller density than regular concrete, and it is beneficial by decreasing the dead load of a structure. Pores in lightweight aggregates, which are incorporated 30% of the concrete mix by volume, contribut

Abstract The high water-absorption of lightweight aggregate causes a high slump loss and poor workability of concrete. A prewetting process is usually recommended to compensate for the workability problem, but its application needs more delicate cons

Incorporating lightweight aggregate (LWA) in concrete decreases its density. The high porosity of LWA contributes to low density but also high absorption characteristics. LWA absorbs water even in ...

In this study, bottom ash sand was classified into sizes of 0.15 mm or less, 0.15∼0.6 mm, 0.6∼1.2 mm, 1.2∼2.5 mm, and 2.5∼5 mm by sand size. The results were evaluated with regard to fine dust removal. The bottom ash sand showed hysteresis in

콘크리트의 자중을 줄이기 위해서 사용하는 경량골재는 흡수율이 높고, 밀도가 낮아, 콘크리트용 골재로 사용할 경우 유동성이 감소하는 단점이 있어, 경량골재에 프리웨팅을 실시하지만,
