As a result of that, the cost of inorganic polymeric binder increases and its impact on our environmental ecology could be severe. To develop low energy-consumption binders and to reduce the amount of recycled glass, waste glass was activated without alkalis in this study. By using an appropriate process of aging and curing, the compressive strength of inorganic polymeric binders can be up to 100MPa. At first, the effects of aging and curing conditions on the compressive strengths of waste-glass binders activated without alkalis are evaluated to propose an appropriate aging and curing process. Then, the relationship between in-service temperature and reaction rate in the well-known Arrhenius theory can be employed to empirically determine the activation energy of waste-glass binders activated without alkalis. In addition, the mechanism of curing can be identified by using Mori and Minegishi method. Finally, the experimental results of FTIR and dissolution tests indicate that the microstructure of waste-glass binders activated without alkalis is similar to that of sodium-lime glass.
