Abstract

This study involves the development of a Hwangto permeable block for rainwater storage tanks. The permeable products that form continuous voids between Hwangto binders and aggregates are fine milled slag powder, which is an industrial by-product generated during the production of Hwangto and iron, and ferro nickel slag. The properties of Hwangto permeable blocks were studied using recycled resource aggregates. The target quality is based on KSF 2394. The Hwangto permeable block for a rainwater storage tank is made of water-permeable material, and the permeability of the Hwangto permeable block itself is 0.1mm/sec or higher, with a physical performance of over 5.0MPa in flexural strength and over 20.0MPa in compressive strength. The physical properties of Hwangto permeable block for rainwater storage tanks were researched and developed. In order to prevent flooding due to heavy rain in summer and the urban heat island phenomenon due to depletion of ground water, continuous pores are formed in the block to secure a permeability function to prevent rainwater from accumulating in the pavement of the floor, and to prevent slippage for comfortable and safe storage.

본 연구는 황토와 무기질 결합재의 수화반응을 이용하여 빗물저류조용 황토투수블록을 개발한 연구로서 제조과정의 산업부산물인 고로슬래그 미분말과 페로니켈슬래그 순환자원을 골재로 활용하고 황토투수블럭을 제작하여 물성분석을 하였다. 도심지 내 투수성 포장을 확대하고 공극이 막혀 투수기능 상실을 방지하여 우수유출저감용 빗물관리시설에 사용하기 위한 것으로써 도시지역에서 열섬현상과 도심 집중강우에 따른 도로침수 포장체 파손 등이 대한 방안으로 활용이 가능하다.
