The maturity method in which the strength increase of cement concrete is expressed as a function of an integral of the curing period and temperature of the concrete has often been applied to its strength prediction. For the purpose of the application of the maturity method to the compressive strength prediction for lightweight polyester ortars using an unsaturated polyester resin as a binder, the lightweight polyester mortars with various catalyst and accelerator contents, are prepared, tested for compressive strength, and the datum temperatures for the maturity equations are estimated. The maturity is calculated by using the maturity equations with the estimated datum temperatures. The compressive strengths of the lightweight polyester mortars are predicted from the maturity-compressive strength relationships.
