초록
콘크리트 같은 많은 건설 폐기물이 빠르게 늘어나고 있으며, 콘크리트에 재활용 골재의 사용이 심각하게 고려되고 있다. 그러나 순환골재의 사용은 품질이 낮기 때문에 매우 한정적으로 사용되고 있다. 그러므로 순환골재의 품질은 콘크리트의 제조에서 매우 중요하다. 본 연구는 지구 온난화의 원인이 되는
Amount of disposed construction materials like waste concrete is growing fast and use of the recycled aggregate for concrete has been seriously considered. But the use of the recycled aggregate is very limited because recycled aggregate has very low quality. Therefore, quality of recycled aggregate is very important in the manufacturing of recycled aggregate concrete. We have studied a series of research according to chemical processes and investigate the alkaline elimination effect of recycled aggregate and quality variation of recycled aggregate by sodium carbonate. Thereafter we have evaluated quality of recycled fine aggregate and experimented quality of this aggregate. As a results, we find that it is easy to eliminate the calcium hydroxide in recycled aggregate by sodium carbonate and the quality of recycled aggregate increase by elimination of alkaline.
