#### Abstract

This study is performed to evaluate the properties of permeable polymer concrete with blast furnace slag and fly ash. The following conclusions are drawn: 1. The highest strength is achieved by 50% filled blast furnace slag powder and fly ash permeable polymer concrete, it is increased 36% by compressive strength and 217% by bending strength than that of the normal cement concrete, respectively. 2. The static modulus of elasticity is in the range of $100{\times}10^3{\sim}130{\times}10^3kgf/cm^2$, which is approximately 43~51% of that of the normal cement concrete. 3. The dynamic modulus of elasticity is in the range of $102{\times}10^3{\sim}130{\times}10^3kgf/cm^2$, which is approximately less compared to that of the normal cement concrete. The highest dynamic modulus is showed by 50% filled blast furnace slag powder and fly ash permeable polymer concrete. The dynamic modulus of elasticity are increased approximately 0~4% than that of the static modulus. 4. The water permeability is in the range of $4.612{\sim}5.913l/cm^2/h$, and it is largely dependent upon the mix design.
