Abstract
A resin concrete composition comprising an allyl ether-modified unsaturated polyester, at least one ethylenically unsaturated monomer and an aggregate, 20% or more of the total dicarboxylic acid units in said allyl ether-modified unsaturated polyester being unsaturated dicarboxylic acid units, the ratio of the number of allyl groups/the number of molecules of unsaturated dicarboxylic acid in said allyl ether-modified unsaturated polyester being 1/10 to 4/1, and said unsaturated polyester having a number average molecular weight of 800-7000. Said composition is suitable for use as thick molded articles and excellent in low temperature curability and adhesion between aggregate and resin. The cured composition is resistant to crack formation and excellent in mechanical properties.
