PURPOSE: To obtain the nonaqueous composition having excellent self-leveling property and physical properties by mixing an inorg. powdery filler, aggregate, fluidizing agent, curing contraction reducing agent and mineral oil with a binder. CONSTITUTION: This nonaqueous composition contains 100 pts.wt. of the following binder, 400-1150 pts.wt. of an inorg. powdery filler and aggregate in total, 0.1-1 pts.wt. of the following fluidizing agent, 3-15 pts.wt. of the following curing contraction reducing agent and 2-5 pts.wt. of mineral oil. The binder is an unsaturated urethane resin consisting of specified components such as unsaturated urethane shown by formula I. The fluidizing agent is a phosphoric ester-type high molecular surfactant shown by formula II. The curing contraction reducing agent is a polyalkyl (meth)acrylate having a 1-8C alkyl. In the formulas, X is a residue formed by removing an isocyanate group from a polyisocyanate, Y is a residue formed by removing a hydroxyl group from a trihydric alcohol, A<1> is a 2-6C alkylene group, A<2> is a 2-4C alkylene group, R1 , R2 and R3 are H or CH3 , (t) is 2 to 5, (p), (q) and (r) are 0 to 2, (q) is 1 to 3, and 2<=p+q+r<=4. |
