초록
The physical, mechanical, water purification and temperature properties of fiber reinforced porous hwang-toh green roof concretehave been evaluated in this study. The effect of the depending on replacement ratio of blast furnace slag to cement was investigatedsuch that the replacement ratio is varied to 0 % and 30 %. Also, the replacement ratios of hwang-toh were 0, 20 and 30 %. Thepolyvinyl alcohol fiber was used for the reinforcing fiber. A series of pH test, unit weight, void ratio, compressive strength, afterpurification and variation of temperature test have been performed to evaluate the performance, water purification effect and temperatureproperties of the fiber reinforced porous hwang-toh green roof concrete. The test results indicate that the physical and mechanicalproperties of fiber reinforced porous hwang-toh green roof concrete is affected by the replacement ratio of the blast furnace slagand hwang-toh contents. Results of purifying water showed that the water purification effect of porous hwang-toh green roofconcrete is about 40 %. Also, the temperature properties test results indicate the green roof blocks using fiber reinforced poroushwang-toh green roof concrete have insulation and temperature reduction effect.
