轻骨料绝热墙体材料选用的骨料可以是导热系数较低的膨胀珍珠岩、粉煤灰和硅酸铝纤维棉。膨胀珍珠岩作绝热墙体的骨料,在国外已大量使用,在国内则大多是将其加工成板材,在一些临时性的建筑中使用。粉煤灰一般采用热电厂排出的灰渣,其质量轻,热阻高,具有保温和胶凝两方面性 The aggregates used for lightweight aggregate insulation wall materials may be expanded perlite, fly ash, and aluminum silicate fiber cotton with low thermal conductivity. Expanded perlite is used as an aggregate for thermal insulation walls and has been widely used abroad. In China, it is mostly processed into plates and used in some temporary buildings. Fly ash generally uses ash from thermal power plants, which is light in weight, high in thermal resistance, and possesses both thermal insulation and gelling properties.
