With the goal of establishing a carbon-neutral society by 2050, environmental awareness has been increasing, and there is a desire that all products be optimally circulated in the life cycle of materials. Thus, the treatment of construction waste has become an important issue. However, because there is no effective reuse method for calcium silicate-based building waste, most of it is disposed of as industrial waste. On the other hand, the glass used for plates and fiberglass is soda-lime glass, which contains silicon and calcium as constituent elements. In this study, glass was produced using calcium silicate and gypsum plates as raw materials. Issues associated with the vitrification reaction and composition and physical properties of the glass alternatives were also examined. Of the two materials, the calcium silicate plate, although colored slightly green, exhibited characteristics that were most similar to those of standard glass. This exploratory experiment suggests that calcium silicate plates could be an alternative raw material for soda-lime-silica glass production.
