The purpose of this study is to explore the use of crushed waste glass as an aggregate in unsaturated polyester (UP) mortar. The unsaturated polyester mortars using crushed waste glass are prepared with three types of fillers, UP-fine aggregate ratios and crushed waste glass replacements for fine aggregate, and tested for weight change, strengths, setting shrinkage and acid resistance. From the test results, the strengths and acid resistance of UP mortars are improved with an increase in the waste glass replacement for fine aggregate. The setting shrinkage of UP mortars has a minimum value of 21.25×10^<-4> at CWG replacement of 50% for fine aggregate. It is reduced by a factor of two or more compared with 0%. In this study, a UP mortar with fly ash as a filler, a UP-fine aggregate ratio of 15% and a waste glass replacement of 50% for fine aggregate is selected as an optimal mix proportion of UP mortar using crushed waste glass. This is enough to assure the use of the crushed waste glass as an aggregate for the production of UP mortar.
