Abstract

PURPOSE:The titled mortar or concrete suppressing shrink properties, having improved strength, obtained by adding a filler to an unsaturated polyester comprising polyvinyl aceate, a specific unsaturated polyester, and an unsaturated monomer. CONSTITUTION:An unsaturated polyester resin comprising (A) 3.0-6.0wt% polyvinyl acetate having a number-average molecular weight of 40,000-100,000 and the rest of (B) an unsaturated polyester (e.g., unsaturated polyester comprising 4mol maleic anhydride, 6mol phthalic anhydride, and 11mol propylene glycol, having a number-average molecular weight of 2,000) in a molar ratio of saturated carboxylic acid to unsaturated polyfunctional carboxylic acid of 1.0-2.0, having a number-average molecular weight of 2,000-4,000 and (C) an unsaturated monomer copolymerizable with the component B is blended with 300-1,000 PHR filler such as sand (gravel), CaCO3, etc. The amounts of the compoments B and C are preferably 40-60wt% and 35-60wt% respectively.
