The present study is to evaluate physical and mechanical properties of porous concrete having non cement that mainly causes carbonemission. This study aims to explore eco-friendly concrete technology capable of reducing the amount of carbon emission due to theuse of normal cement by substituting it with non cement porous concrete to which alkali-activator and blast-furnace slag powder areimpregnated. As experimental variables, 5 %, 6 %, 7 %, 8 %, 9 % and 10 % of alkali-activator were substituted as binders andapplied. Testing evaluated in this study were pH value, void ratio, compressive strength and residual compressive strength shownafter being immersed in H2SO4 solution and Na2SO4 solution. The test results were compared with those tested with the use ofporous concrete to which 400 kg/m3 of unit cement amount was applied as binder. In consequence, it was concluded that; as forpH value, it was decreased than was the case in which cement was used, but increased with the more the use of alkali activator;as for void ratio and compressive strength, the mix proportion in which 9 % and 10 % of alkali activator were applied in terms ofsubstitution ratio showed the result similar to the mixture in which 400 kg/m3 of unit cement ratio was applied; and, as for residualcompressive strength in the case of being immersed in H2SO4 solution and Na2SO4 solution, the compressive strength was increased,thus leading to improved chemical resistance.
