Setting time properties of cement matrix according to photosynthetic bacterial dilution ratio

광합성 세균 희석 비율에 따른 시멘트 경화체의 응결 특성

In recent years, harmful substances and fine dust in the air are caused by respiratory and cardiovascular diseases through various mechanisms when they are introduced into the human body through respiration, thereby exacerbating human health and causing cancer by prolonged exposure do. In order to prevent such fine dust from being introduced into the room and to improve indoor air quality, improvement of air quality has attracted attention. Among indoor air pollutants, fine dust and CO₂ are pollutants that are directly affected by indoor number and activity. The purpose of this study is to evaluate the basic performance of cement matrix using photosynthetic bacteria as a basic study of fine dust and CO₂ adsorption type matrix to suppress indoor air pollution and improve air quality.
