PROCESS OF PRODUCING GEOPOLYMER USING WASTE GLASS AND GEO CONCRETE COMPOSITION USING THE GEOPOLYMER

摘要

PURPOSE: A method for manufacturing a geopolymer and a geoconcrete composition using the waste glass are provided to recycle the waste glass as an inorganic binder for the geoconcrete composition and to improve the treating efficiency of wastes. CONSTITUTION: A method for manufacturing a geopolymer using waste glass includes the following: Waste glass is washed, dried, and pulverized. An alkaline component is introduced into the pulverized waste glass to adjust the mixing ratio of the pulverized waste glass. The waste glass with the adjusted mixing ratio is stirred to be dissolved at 60-80 rpm and at a pressure of 15-20kgf/cm^2 in order to obtain a liquid geopolymer. The waste glass with the adjusted mixing ratio includes 17.5-19.5 weight% of Na_2O+K_2O, 28-30 weight% of SiO_2, 0.5-1.2 weight% of Al_2O_3, 0.8-1.4 weight% of CaO, and 0.4-0.8 weight% of MgO. A geoconcrete composition includes 1-30 weight% of the geopolymer.
