Abstract

본 발명은 석회석 소성과정과 석회석 원광석 수세과정에서 부산되는 슬러지를 원료로 하여 아스콘을 제조하기 위한 것으로 상기 석회석 슬러지를 수분을 제거한 분말 형태로 가공한 뒤 아스팔트와 혼합하여 혼합물을 얻고 상기 혼합물에 골재, 석분 및 모래등을 혼합하여 아스콘으로 제조하므로써 종래 폐기되던 석회석 슬러지를 재활용하여 고부가가치화하고 환경오염에도 큰 효과를 가질 수 있도록 한 것이다.The present invention is to prepare ascone as a raw material of the sludge by-produced in the limestone calcining process and the limestone ore washing process to process the limestone sludge in the form of a powder to remove moisture and then mixed with asphalt to obtain a mixture and aggregate in the mixture, By mixing lime powder and sand to produce ascon, the limestone sludge that has been disposed of in the past is recycled to have a high value and have a great effect on environmental pollution.
