CERAMIC PAVING MATERIAL AND ITS PRODUCTION

摘要

PURPOSE:To obtain a ceramic pavig material high in product yield and having effective surface property though the whole raw material consists of wate materials. CONSTITUTION:The ceramic paving material uses following material of 1-4 formed from the waste as strutural materials. 1. 20-40wt.% powder of pots head and/or tile scrap having 3-1mm particle diamter. 2. 10-30wt.% sewage sludge molten slag and/or blast furnace slag having 3-1mm particle diameter 3. 5-40wt.% lacustrine sludge dried powder and/or municipal waste incineration ash having <=1mm particle diameter 4. 10-30wt.% SiO2-Al2O3 based waste powder of fine powder and having >=1500 deg.C m.p. The paving material is produced by kneading and molding the raw materials of 1-4 and firing at 1050-1300 deg.C.
