이 연구는 불포화 폴리에스터 수지를 이용한 고강도 폴리머 콘크리트를 제조하여 구성재료와 첨가제의 변화에 따른 역학적 특성을 실험적으로 구명한 것이다. 그 결과 제조된 폴리머 콘크리트는 재령7일에서 압축강도$1,291~1,445kg/cm^2$, 할열인장강도 $106~145kg/cm^2$, 휨강도 $182~235kg/cm^2$를 발현하였으며, 이들에 대한 탄성계수 및 포아슨비를 구해 보았던 바 $2.8~3.8{\times}10^5\;kg/cm^2$, 0.21~0.32였고, 최대압축변형도는 0.005~0.0065로서 시멘트 콘크리트에 비해 매우 크게 나타났다.

This study was carried out to develop a procedural method to produce high strength polymer concrete using unsaturated polyt.ster resin and to examine its mechanical properties. Various mechanical properties were analyzed with respect to materials and additives. A method to produce high strength polymer concrete was successfully developed. Comperssive strength of $1,291~1,445 kg/cm^2$, splitting tensile strength of $106~145 kg/cm^2$ and flexural strength of $182~235 kg/cm^2$, at age of 7days wer-e achieved from the cylinderical ;md beam specimen prepared with the method. Modulus of elasticity. Poisson's rntio and the ultirnate corn pressive strain of cylinderical specimen were $2.8~3.8{\times}10^5\;kg/cm^2$. 0.21~0.32, and 0.005~0. 0065, respectively. Modulus of elasticity of the polymer concrete was smaller than that of hlgh strength cement concrete while the maximum compressive strain was very larger than that of high strength cement concrete.
