A Fundamental Study in order to Utilize Waste Glasses Powder as Admixtures of Repair Mortar

폐유리 미분말을 보수모르타르의 혼합재료로 활용하기 위한 기초적 연구

The waste glasses among plenty of wastes put out lately is limited in recycling and reusing, and the phenomenon hasn't been improved quite much. And besides, the recycling rate shows the 70.1%, relatively low. These waste glasses is currently used for road pavement materials, interior and exterior decorating materials in architecture, road painting meterials, auxiliary lagging materials for heat-retaining, coldness-retaining and soundproofing, and glass bottles. 30% of waste glasses powder is, however, not reused pratically. Therefore, in this research, we operated some tests including flow of mortar mixed with waste glasses powder, setting time, rheology and compressive strength to utilize waste glasses powder put out in the precess of recycling for admixture for repair mortar. As a result, we've found out that we can utilize waste glasses powder for admixture for repair mortar.
