The Study on the Engineering Properties of High-Strength Glossy Concrete Tiles Using Waste Concrete Powders

재생 미분말을 적용한 고강도 광택 콘크리트 마감재의 공학적 특성에 관한 연구

This Study is concerned workability and the physical properties for practical use of waste concrete powder originated from the manufacturing progress of waste concrete aggregate and it apply to concrete tile. Also because it is important that concrete tile has to ensure the surface moisture stability, for solving the problems aplied curing method is air-dried and autoclave curing. As the result, the physical properties, such as fluent properties, compressive strength, surface hardness and surface glossiness, were decreased with increase of replacement ratio of waste concrete powder, also surface stability was weaked about moisture. But by autoclave curing, it is possible that compressive strength and surface hardness increased, and surface moisture stability is ensured.
