摘　　要：随着建筑工程的不断发展,对建筑节能的要求不断提高,各种保温隔热材料得到了不同程度的推广和应用。石膏基玻化微珠保温砂浆作为近些年发展起来的一种新型无机保温隔热材料,以其众多优点得到了较大规模的推广和应用。但在保温材料性能验收工程中,对于实际使用石膏基玻化微珠保温砂浆是否按照设计要求真实掺加膨胀玻化微珠存在争议,因此,以实际工程为典型案例,通过对已施工石膏基玻化微珠保温砂浆进行扫描电镜(SEM)、点面能谱(EDS)分析和X射线衍射(XRD)分析等微观分析方法,从外观形貌、元素成分和矿物组成角度对是否掺加膨胀玻化微珠进行鉴定分析,为此类工程保温材料的性能验收提供指导和帮助。With the continuous development of construction projects,the requirements for building energy conservation have been continuously improved,and various insulation materials have been promoted and applied to varying degrees.As a new type of inorganic insulation material developed in recent years,gypsum-based vitrified microbeads insulation mortar has been widely promoted and applied due to its numerous advantages.However,in the performance acceptance project of thermal insulation materials,there is controversy over whether the actual use of gypsum-based vitrified microbeads insulation mortar actually adheres to the design requirements by adding expanded and vitrified beads.Therefore,taking practical projects as typical cases,through microscopic analysis methods such as Scanning Electron Microscopy(SEM),point-to-surface energy spectroscopy(EDS)and X-ray diffraction analysis(XRD),the identification and analysis of whether the expanded and vitrified beads materials are added to the gypsum-based vitrified microbeads insulation mortar from the perspective of appearance,element composition and mineral composition are carried out,providing guidance and assistance for the performance acceptance of such engineering insulation materials.
