In order to obtain epoxy concrete that can adapt to different strengths and different environmental conditions, this paper innovatively constructed a new type of accurate epoxy concrete mix calculation logic and calculation method through literature investigation, analysis, and test, which can make the process of calculating epoxy concrete mix ratio more concise and precise. In this paper, a new type of epoxy concrete mix with a strength class of C30 is designed, which can provide a reference for engineers and technicians to design accurate epoxy concrete mix better. It also provides some reference value for improving the mix ratio design method and engineering application of epoxy resin concrete.
