STUDY OF THE MODULUS OF ELASTICITY OF POLYMER CONCRETE COMPOUNDS AND COMPARATIVE ASSESSMENT OF POLYMER CONCRETE AND PORTLAND CEMENT CONCRETE

Polymer concrete (PC) has excellent mechanical strength and durability that reduce the need for maintenance and frequent repairs such as are required for conventional concrete. However, PC can be more expensive than conventional concrete, primarily due to the resins used in its construction. This article reports on a study undertaken to assess the modulus of elasticity of polymer concrete (PC) compounds produced using two types of binders: orthophtalic or isophtalic polyester. Orthophtalic polyesters have a much lower cost than isophtalic polyesters, which are normally used in the production of PC. The concentrations of polymer used were 12% of orthophtalic polyester and 13% of isophtalic polyester by weight of the dry materials. Fly ash was used as a filler and compositions with 8%, 12%, 16% and 20% of ash by weight of aggregate were studied. Results indicate that all compositions assessed in this study display high modulus of elasticity values. Statistical analysis of the data reveals that the type of resin and the concentration of fly ash, both in isolation and in combination, have a significant effect on the modulus of elasticity of these compounds. There was an overall increase in the modulus of elasticity as the concentration of fly ash increased.
