혼화재료로서 석분토의 재활용 가능성 평가

Stone-Dust are inevitable by-products of almost rocky mountains which produce artificial sands in korea. The annual amounts of Stone-Dust is over 80,000㎥ approximately. Almost pre-existing Stone-Dust piled up out in the open space on disposed of industrial waste, it can result in critical environmental problem. The aim of this study is to promote the recycling of industrial waste as a kind of material of admixture. This study conducted some experiments such as pozzolan reaction test and flow test, compressive strength of mortar using Stone-Dust in heat-treatment. As a result of, compressive strength of mortar using stone-dust in heat-treatment is superior in the case of 700℃ 90min.
