SOLIDIFYING AGENT FOR SLUDGE, HARDENED PRODUCT USING THE SAME AND MANUFACTURING METHOD OF THE BUILDING MATERIALS USING THE HARDENDED PRODUCT

摘要

A solidifying agent for sludge, a hardened body manufacturing method using the same, and a construction material manufacturing method using a hardened body are provided to prevent the outflow of pollutants contained in the sludge and to easily transport and carry the sludge by firmly solidifying the sludge. The solidifying agent for sludge consists of SiO2(Silicon Dioxide) of 30-40wt.%, Al2O3(Alumina) of 10-20wt.%, Fe2O3(Iron Oxide) of 4-6wt.%, MgO(Magnesium Oxide) of 5-8wt.%, CaSO4(Calcium Sulfate) of 15-25wt.%, CaCl2(Calcium Chloride) of 1-3wt.%, CoCl2(Cobalt Chloride) of 3-5wt.%, NaCl(Sodium Chloride) of 20-25wt.%, KCl(Potassium Chloride) of 25-30wt.%, MgCl(Magnesium Chloride) of 5-15wt.%, and citric acid of 2-3wt.% to CaO(Calcium Oxide) of 100wt.%. The type of the solidifying agent for sludge is one selected from a group composed of powder, liquid, and gel.
