PROBLEM TO BE SOLVED: To obtain a hardening resin composition capable of giving resin mortal or resin concrete excellent in workability, hardening properties and weather resistance, and having little or no hardening shrinkage. SOLUTION: This hardening resin composition is obtained by compounding a binding material, a shrinkage-lowering material, an inorganic filter and an aggregate. As the binding material, a polymerizing liquid resin comprising at least one kind of monomer component A selected from (meth)acrylic acid, (meth)acrylic esters and other vinyl monomers, and a resin B soluble in the monomer component A is used. As the shrinkage-lowering material, a polymer insoluble in the monomer component A and dilatable is used. |
