CONCRETE COMPOSITION HAVING COFFEE CARBONIZED ASH
The present invention presents a concrete composition mixed with coffee ground ash, which is a concrete composition in which a mixture of cement and coffee ground ash, fine aggregate, coarse aggregate, and water are mixed, wherein the coffee ground ash is carbonized at a high temperature of 700℃ or higher, and as the carbonization temperature of the coffee ground ash increases, a mixing ratio of coffee ground ash in the mixture increases. By mixing coffee grounds with concrete, antifouling performance, dehumidification performance, and deodorization effect of the concrete are improved, thereby preventing rusts of a reinforcing bar placed inside the concrete and preventing a problem of strength deterioration of the concrete.
본 발명은 시멘트와 커피찌꺼기 애쉬의 혼합물, 세골재, 조골재, 물이 혼입된 콘크리트 조성물에 있어서, 상기 커피찌꺼기 애쉬는 700℃ 이상의 고온에서 탄화되고, 상기 커피찌꺼기 애쉬의 탄화온도가 높아질수록, 상기 혼합물에서 커피찌꺼기 애쉬의 혼입비율이 증가하는 것을 특징으로 하는 커피찌꺼기 애쉬가 혼합된 콘크리트 조성물을 제시함으로써, 커피찌꺼기를 콘크리트에 혼합하여 콘크리트의 방오성능, 제습성능, 탈취효과를 향상시키고, 콘크리트 내부에 배근되는 철근의 녹을 방지하면서도, 콘크리트의 강도저하 문제를 방지할 수 있도록 한다.
