Abstract
This study experimentally investigated the deformability characteristics of bisphenol A-type epoxy resin-based polymer concrete produced using two types of hardener and four types of filler. In particular, the basic properties of epoxy resin polymer concrete, including the modulus of elasticity, setting shrinkage, and thermal expansion, were experimentally investigated to obtain basic data for evaluating compatibility and dimensional stability. The properties of the epoxy resin polymer concrete were determined when different types of hardener and filler were employed. Differences in deformability can be identified based on these properties. In the present study, the setting shrinkage, coefficient of thermal expansion, and modulus of elasticity were lowest when fly ash was employed as one of the four fillers. Hence, it is advantageous to use fly ash as a repair material for ordinary Portland cement concrete structures. Therefore, the results of this study will be helpful when selecting the types of hardener and filler needed to tailor the epoxy resin polymer concrete produced to be suitable for a particular application.

Summary
In order to keep pace with rapid developments in the construction field, there is a strong demand to modify the properties of concrete to produce new types [1]. Among those recently developed, the most representative construction material is polymer concrete (PC). Exothermic reactions occur, and long polymer chains are generated during the curing process. The properties of PC depend highly on the types and contents of the resin, shape and size of the aggregate, filler type, and curing conditions [3,4,5]
