  • 본 연구에서는 고강도 콘크리트 및 시멘트 복합체의 밀실한 내부 구조로 인한 급격한 내부 습도 저하 및 수화도 저하 등의 영향을 파악하고자 하였다. 내부 Si 수화도 변화 검증을 위해 폐유리발포비드를 경량골재로 사용하였으며, 중장기에 걸쳐 내부 미반응 수화물의 저감 및 수화물 형성 경향을 파악하였다. 폐유리발포비드는 5, 10, 20 % 혼입되었으며 프리웨팅하여 사용하였다. 폐유리발포비드의 혼입률이 증가함에 따라 강도는 감소하는 경향을 보였다. 이와 함께 XRD 분석, TGA 분석 및 Si NMR 분석을 통해 프리웨팅된 폐유리발포비드의 혼입량이 내부에 증가할 때, 페이스트에 수분이 공급되는 것으로 내부 Si의 수화 정도는 달라지는 것으로 판단된다.

  • Recently, heat island and dry island phenomena occur frequently due to land surface development and excessive energy consumption in urban areas. As a result, the surface temperature of the building and the entire temperature of its surroundings are increased, and as a result, the durability of the building is rapidly deteriorated. In order to suppress these causes, a method of maintaining the temperature of road heating wires was implemented as a temporary measure, but this did not predict climate change. Therefore, this study is a method to measure the compressive strength, density, and thermal conductivity of lightweight concrete using waste glass foam beads. After fabricating a simple chamber, the temperature and humidity of the inside and outside were measured with an Arduino device in consideration of external factors. Therefore, if waste glass foam beads made through proper mixing are constructed in the urban center, the quality of the urban can be improved.
