PURPOSE:To make cement composition have comparable properties with ceramic tile as building material for decorating wall by only casting in frame mold without subjecting to baking process by treating waste cotton with specific fireproofing agent and mixing into cement composition together with vegetable fiber. CONSTITUTION:A) 93-77 pts.wt. at least one of Portland cement and alumina cement is mixed with B) 2-10 pts.wt. at least one of montmorillonite, acid clay and bentonite, C) 2-10 pts.wt. at least one of Zirconia and magnesia, D) 0.5-3 pts.wt. alkali (earth) metal stearate, E) 0.5 pt.wt. alkali metal salt of naphthalenesulfonic acid and F) 1-3 pts.wt. alkali metal bicarbonate or calcium chloride to obtain a cement composition. Then, 100 pts.wt. said cement composition is mixed with 8-40 pts.wt. fibrous aggregate containing waste cotton treated with a solution containing ammonium phosphate, guanidine phosphate and magnesium chloride or calcium chloride and 100-200 pts.wt. inorganic aggregate to afford a mortar composition for producing non-baked tile. |
