Abstract

In this study, effective parameters for Polymer Concrete (PC) based on epoxy resin such as filler, hardener, and solvent are investigated. Rice husk and broom stem ashes as fillers with a mixture of 50{50% acetone-toluene as solvent in the preparation of PC samples were used. According to experimental results, the addition of fillers improved compressive, flexural, and chemical strengths of the PC samples. In the sample with 18. 4% polymer, given the addition of rice husk ash with a ratio of filler-aggregate 0. 075, compressive strength improved by 21%. For the sample with the broom stem ash ratio of filler-aggregate 0. 09, the flexural strength improved by 27%. In addition, experimental data proved that the addition of optimum amount of solvent improved the performance and enhanced the compressive and flexural strengths. However, the excess amount of solvent may reduce the adhesiveness of the polymer; therefore, it may have negative impact on PC. The combination of hardener-resin may affect the strength of PC. Amine type of hardener with a low equivalent weight improved by 27% and 13% on compressive and flexural strengths. Moreover, elasticity modulus increased compared with the samples having a high equivalent weight of amine type hardener.
