Abstract: Polymer mortars have become more popular as repair materials compared to conventional mortars. This paper reports the investigation on different mechanical properties of polyester mortar cured at ambient temperature and 80oC. Unsaturated polyester resin, which is known for its cost performance efficiency is used to bind the aggregates. A comparative study was made on properties of polymers. It was found that thermal cured specimens exhibited improved compressive, flexural and split tensile strength compared to ambient cured specimens. However ambient cured samples exhibited a greater modulus than thermal cured samples. Since the polymer mortar exhibits high modulus of elasticity and ductility, it can be recommended as building materials for construction of earthquake retaining structure, repair works etc...

Keywords: Polymer mortar, polyester resin, compressive strength, modulus, flexural, split tensile
