Although GGBS has been produced more than 12 million metric tons every year due to the development of the steel industry, the consumption decreases because of recession in the cement industry, which is a major market of the steel industry. Therefore, it is necessary to create a new market and increase its added value. In addition, extrusion molding panels are not yet widely used due to their lower economic feasibility than existing dry walls in spite of their excellent performance. Therefore, this study reviews strength properties of extruding solid according to the amount of GGBS used in order to create high added value of GGBS and improve economic feasibility of extruding panels. It is shown that the initial compressive strength is higher than a base due to pozzolanic reaction promoted by Ca(OH)2 o f OPC. On the other hand, flex ural s trength is l ower than a base due t o the difference between the amount of fibrous materials. |
