Recently polyester resin concrete has become widely used in the field of construction works in Japan, but a method of predicting its strength has hardly been proposed yet. The purpose of this study was to examine the properties of orthophthalate-type polyester resin concrete with various styrene-unsaturated polyester ratios (ST/UP) , and then to find the method for strength prediction. Polyester resin concrete was prepared with variation of ST/UP, and the effects of ST/UP on the properties such as the compressive, tensile and flexural strengths, stress-strain relationship, modulus of elasticity and length change were discussed. It is concluded that the strength prediction of orthophthalate-type polyester resin concrete is possible to some extent by applying the ST/UP-strengths relationships, and that the properties such as the stress-strain relationship, modulus of elasticity and length change are considerably affected by ST/UP.
