In this study compressive and shear strength reduction of green-type polymer concrete and effect of steel-fiber reinforcement were investigated to make clear the possibility of using vast amount of the blast furnace slag powder and recycled coarse aggregates for reducing CO₂emission and resolving a problem of the natural environmental disruption by using 2nd class blast furnace slag powder and 1st class recycled coarse aggregates. Test results showed that when blast furnace slag powder with displacement ratio, 80% and recycled coarse aggregates with displacement ratio, 100% were used at the same time, the compressive strength were reduced 13% at 10 days, 5% at 28 days, 2%~4% at 56 days, but by steel-fiber reinforcement the reduced compressive strength were recovered and increased 2%~4%, and that diagonal shear strength of short beams were reduced 12%~15%, but by steel-fiber reinforcement the reduced shear strength were recovered completely and increased 10% above ln comparison with that of base concrete specimen.
