An Experimental Study of the Effects of the LCD Wasted Glass Powder on the Durability of Concrete

Various display devices are being used owing to the changes in the living environment. This also greatly increases the use of liquid crystal display (LCD) glass. In other words, 28,000 tons/year of LCD wasted glass are generated in Korea. In this study, the durability properties of concrete made with LCD wasted glass powder were evaluated. Consequently, concrete made with LCD wasted glass powder showed the lowest fluidity. In addition, the durability properties of concrete made with LCD wasted glass powder were lower than those of concrete made with only the ordinary Portland cement (OPC) or made with OPC and fly ash (FA). To promote the use of LCD wasted glass powder as a material for concrete, further studies on the activation method for main components (SiO2andAl2O3)arerequired.
