FILLER FOR CAVITY

摘要

PROBLEM TO BE SOLVED: To obtain one pack type filler excellent in fluidity and self-packing property, free from occurrence of crack due to drying even under air drying conditions and capable of ensuring strength by mixing a curing material composed of a slag composition consisting of specific components such as CaO, SiO2 and Al2 O3 and cement with water. SOLUTION: This filler for cavity is obtained by mixing preferably 100 pts.wt. curing material comprising preferably 100 pts.wt. slag composition having 0-37wt.% CaO content, 23-90wt.% SiO2 content and 0-40wt.% Al2 O3 content, 0.1-50wt.% on or more components selected from iron oxide, an alkali content, phosphorus content, titanium oxide, manganese oxide and magnesium oxide and/or 0.1-10wt.% halogen content and preferably 5-30 pts.wt. cement with preferably 60-120 pts.wt. water. The slag composition is preferably obtained by using preferably various waste products such as burned materials of sewage sludge raw materials, burned ash of wastes and industrial waste products as raw materials, as necessary, adjusting these components with clay and limestone, and melting these components at high temperature and quenching and pulverizing these components.
