Polyester polymer resin concrete is a type of concrete that incorporates polyester polymer resins as a binder instead oftraditional cement. In this study, concrete was made using three resins: vinyl ester resin, superior vinyl ester resin, andbisphenolresin. The ingredients of polyester polymer resin concrete are three types of polyester resin, 1-2% of Methyl ethylketone peroxide (MEKP) as the catalyst, Cobalt Octoate as the Accelerator and N, N-dimethylaniline as the promoter of 1%is used to make the binding resin. Along with binding resin calcium carbonate as filler and fine aggregate (normal riversand)passing through 2.36 mm sieve and retained on 600-micron sieve and course aggregate of size 6mm were used to make theconcrete. 36 trail batches were carried out for preliminary investigation targeting a compressive strength of 70 MPa. Theshortlisted batches were taken for detailed investigation on mechanical and durability properties. The stress strain behaviourisstudied and dynamic modulus,poisons ratio is calculated with various correlative equations for mechanical properties. Thedurability properties of the resin concrete were assessed as per ACI 515.2R-13 [1966] for the acid and base solutions. Byimmersing the samples in three diluted acids and two alkaline media, such as 10% sulphuric acid, 10% nitric acid, 10%hydrochloric acid, 10% sodium sulphate, and 10% magnesium sulphate, the durability property is assessed. Variations incompressive strength, mass, and the look of the submerged samples, among other variables, have been studied and it foundthat the Vinyl ester resin concrete possesses a higher acid resistance property.
