Recently, as the national policy of green growth is promoted, construction field also makes an effort to reduce CO2 gas released when producing cement continuously. In other words, as the method solving environmental pollution and resources exhaustion, lots of mineral material compounds such as blast furnace slag powder which is industrial by-product, fly ash, red mud, etc. are examined to be used as the substitute good of cement. Therefore, this study intended to supplement the weaknesses of blast furnace slag powder and red mud with blast furnace slag powder and red mud, as the substitute good of cement, not concrete compound, manufacture inorganic composite of cement world, which can be made with only alkali accelerator at normal temperature, without high-temperature plasticity. After confirming kinds of red mud and alkali liquids and physical property by the change of addition rate with fundamental experiment, proper mix was drawn by combining blast furnace slag powder. |
