Research Abstract |
The recycling process of leftover gypsum boards from new construction and demolition sites currently requires intermediate treatment. The boards are separated into their paper and gypsum components and the non-recyclable components are discarded into controlled landfills. However, problems such as landfill capacity shortage and the refusal of privately owned landfills to accept such materials have made the recycling of discarded gypsum an urgent challenge. Bassanite produced by heat-treating the dihydrate gypsum obtained from discarded gypsum boards, solidifies when water is added. Therefore, research is underway into the exploitation of this characteristic of bassanite for the development of a soil improvement material. In this study, we investigate the applicability of recycled bassanite as a material for soil improvement using existing soil.
