Effects of curing temperature and hardener type on the mechanical properties of bisphenol F-type epoxy resin concrete

This study investigated the effects of curing temperature and hardener type on the compressive strength, flexural strength, and modulus of elasticity of concrete made with bisphenol F-type epoxy resin as a binder. The results showed that a higher curing temperature resulted in faster strength development at an early age, and the strength was greatest for the mixture with meta-xylenediamine (MXDA), followed by modified cycloaliphatic amine (MCAA) and isophorone diamine (IPDA). The higher curing temperature resulted in a greater modulus of elasticity and ultimate strain, as well as strength, and the effect of hardener type was in the same order as was observed for strength development. Also, an equation to predict the modulus of elasticity based on compressive strength was presented for each hardener type. It can be concluded that the compressive strength, flexural strength, and modulus of elasticity of bisphenol F-type epoxy resin concrete was affected by both curing temperature and hardener type.
