PROBLEM TO BE SOLVED: To obtain the subject composition excellent in workability and finish in summer of a high-temperature environment. SOLUTION: This resin composition for resin concrete comprises (A) a total of 100 pts.wt. of 30-94.8wt.% of a monomer having only one polymerizable double bond in the molecule and free from hydroxyl group, 5-69.8wt.% of a polymer, 0.1-5wt.% of paraffin wax and 0.1-5wt.% of a tertiary amine, (B) 3-45pts.wt. of a hydroxyl-bearing (meth)acrylic ester monomer, and (C) 1-23 pts.wt. of a (meth)acrylic ester monomer having at least two polymerizable double bonds in the molecule. |
