PRODUCTION OF BRICK EFFECTIVELY USING SLUDGE AND MUNICIPAL REFUSE

机译:有效利用污泥和城市垃圾生产砖

摘要

PROBLEM TO BE SOLVED: To provide easily usable materials having generality and useful for civil engineering and construction from sludge and municipal refuses as raw materials at a low cost. SOLUTION: This method for producing bricks effectively utilizing sludge and municipal refuses comprises directly pouring the melted slag of the burned ash of the sludge and municipal refuses in the melted state into water to granulate the slag with the water, mixing 100 wt.% of the obtained granulated slag with 20-100 wt.% of a low refractoriness clay mineral and water, kneading the mixture, press-molding the plasticized product, drying the molded product and subsequently calcining the dried molded product at 600-1,200 deg.C. The granulated slag can be used as such to simply produce bricks, and the bricks contain glass bonds due to the calcination at 600-1,200 deg.C, and thereby have permanent lives. Since the bricks can be colored with one or more pigments, the uses of the bricks are spread. The method for producing the bricks saves the expenditure of the country and municipalities as the effective utilization of general wastes and is useful for the production of the effective materials.
