Özet

In this study, the use of natural and expanded perlite aggregates in polymer concrete production was evaluated and the effects of these aggregates on the behavior of polymer concrete in aggressive environments were investigated. Unsaturated polyester resin and vinylester resin were preferred as binding materials in polymer concretes. Perlite was used instead of quartz aggregate at 0% (control), 5% and 10%. The produced samples were subjected to tests by keeping them in acid and sulfate solutions for 28 and 56 days. According to the experimental results, the highest weight and compressive strength loss was observed in samples containing 10% expanded perlite for both resin types compared to the control group. When samples containing natural perlite were examined, samples produced with vinylester resin showed lower weight and strength losses than those with polyester resin. In general, an increase in weight and compressive strength losses was observed in all samples as the waiting time in both acid and sulfate solutions increased. The findings reveal that the type and ratio of perlite, as well as the type of resin, have significant effects on the behavior of polymer concretes in aggressive environments.
