<p>PROBLEM TO BE SOLVED: To obtain a sulfur-contg. mortar compsn. ensuring high strength and superior water resistance by blending sulfur with inorg. waste treated with a surface treating agent and a water resistance improver or a flame resistance imparting agent. SOLUTION: This sulfur-contg. mortar compsn. contains 20-90wt.% sulfur (A), 80-10wt.% inorg. waste treated with a surface treating agent (B) and 0-30wt.% water resistance improver or flame resistance imparting agent (C) based on the total amt. of the components A, B, C. The inorg. waste is, e.g. a waste fluidized catalytic cracking catalyst, a waste desulfurization catalyst, waste clay or coal ash. The surface treating agent is, e.g. a silane coupling agent, a titanate coupling agent or an aq. polymer dispersion. The component C is, e.g. asphalt or a thermoplastic resin. Asphalt having a penetration of 0.1-20 is preferably used because a higher strength molded article is obtd.</p> |
