摘   要 ：試驗研究了普通硅酸鹽水泥、硫鋁酸鹽水泥、礦粉三種膠凝材料以及保溫骨料玻化微珠和功能組分對石膏基保溫砂漿性能的影響 。通過研究表明：摻入硫鋁酸鹽水泥可以顯著提高石膏基保溫砂漿的力學性能； 當玻化微珠與復合膠凝材料質量比為 5 :  10 、纖維素醚為 0. 2% 、引氣劑為 0. 005%時，石膏基保溫砂漿的導熱系數為 0. 08 W/  ( m ·K) 、強度為 1 . 0 MPa 、體積密度為 370 kg/m³  , 同時砂漿的和易性 、可批刮性也滿足施工要求。

Abstract: The effects of ordinary Portland cement, sulfoaluminate cement, mineral powder, three kinds of cementitious materials, as well as thermal insulation aggregate vitrified microbeads and functional components on the performance of gypsum-based thermal insulation mortar were investigated experimentally. The research shows that adding sulfoaluminate cement can significantly improve the mechanical properties of gypsum-based thermal insulation mortar; when the mass ratio of vitrified microbeads to composite cementitious material is 5:10, cellulose ether is 0.2%, and air-entraining agent is at 0.005%, the thermal conductivity of the gypsum-based thermal insulation mortar is 0.08W/(m?K), the strength is 1.0 Mpa, and the bulk density is 370kg/m3. At the same time, the workability and batch scraping of the mortar also meet the construction requirements.

Keywords：desulfurized gypsum; insulation mortar; vitrified beads
