Compressive strength properties of concrete using Waste Concrete Powder as a cement substitute

폐콘크리트 미분말을 시멘트 대체제로 활용한 콘크리트의 압축강도 특성

Recently, a number of problems due to the CO₂ emissions are occurred. Therefore, it is a movement to restrict this activity. The research is being carried out steadily for recycling waste concrete from the cement paste based fine powder, which accounts for over 60% of construction waste as a recycled cement. In this study, the conclusion was obtained as a result of the research conducted, and then, replacing the main material of cement concrete to solve the above problem by reducing the amount of cement used Waste Concrete Powder. The more concrete results page replacement ratio of fine powder increases, the flow value of the concrete is lowered, the strength was remarkably reduced when the page Concrete Powder.
