摘　　要：粉刷石膏砂浆具有质量轻、微膨胀、导热系数小、与建筑基层连接较紧密等优势。因而以石膏作为胶凝材料、膨胀珍珠岩作为骨料制备轻质粉刷石膏砂浆,采用了正交试验法,研究了不同掺量的建筑石膏、膨胀珍珠岩、纤维素醚及重钙对粉刷石膏砂浆的抗压强度、粘结强度、密度等性能的影响规律,最终确定了粉刷石膏砂浆的配合比。Plastering gypsum mortar has the advantages of light weight,micro expansion,low thermal conductivity and close connection with building base,so it is prepared with gypsum as cementitious material and expanded perlite as aggregate.By using the orthogonal test method,this study researches the influence of different amounts of building gypsum,expanded perlite,cellulose ether and heavy calcium on the compressive strength,bonding strength and density of plastered gypsum mortar,and finally determine the mix proportion.
