| Abstract: | The basic properties of polyester resin mortar have been studied. These properties included compressive strength, flexural strength, modulus of elasticity, shrinkage, and resistance to sulfuric acid. The main variables were the polymer content, the ratio of coarse sand to filler, the method of curing, and the age. The properties of Portland cement mortar were also studied for comparison. Polyester mortar shows a higher rate of hardening, higher strength, and higher resistance to sulfuric acid than cement mortar. On the other hand, polyester mortar shows lower modulus of elasticity and higher shrinkage than cement mortar. |
