Effect of Agro-Waste Ash on Mechanical Properties of Epoxy Polymer Concrete

This paper focuses on addition of fillers in epoxy resin and aggregate for polymer concrete (PC) preparation. For the preparation of PC, two kinds of fillers, i.e. rice husk ash and broom stem ash were used. According to experimental results, addition of fillers had a positive impact on the physical and mechanical properties of the PC. In the PC sample with rice husk ash, with the filler/aggregate ratio of 0.075 and 18.4% polymer, maximum compressive strength of 86.41 Mpa was obtained; while the compressive strength of the polymer concrete without filler was 71.2 Mpa. The PC sample with broom stem ash, with the filler/aggregate ratio of 0.12 and 23% polymer showed the maximum flexural strength.
