摘要：以岩棉纤维为增强材料，有机硅为改性剂，采用物理发泡法制备了超轻泡沫混凝土，并研究了其性能和微观结构。结果表明：随着有机硅掺量的增加，试件的干密度、抗压强度、体积吸水率和导热系数均降低；随着岩棉纤维掺量的增加，试件的干密度变化不明显，抗压强度增大，体积吸水率和导热系数先降低后升高；当有机硅掺量为1.0%、岩棉纤维掺量为2.0%时，超轻泡沫混凝土的综合性能最优；超轻泡沫混凝土中的气孔多为近球形，孔径尺寸分布在50~1 000 μm之间，不同孔径气孔相互堆叠且分布均匀。 Abstract: Using rock wool fiber as reinforcement material and organic silicon as modifier, the ultra-light foam concrete was prepared by physical foaming method, and the properties and microstructure were studied. The results show that the dry density, compressive strength, volume water absorption and thermal conductivity of the sample decrease with the increase of the organic silicon content. With the increase of rock wool fiber content, the dry density of the sample does not change significantly, the compressive strength increases, the volume water absorption and thermal conductivity first decrease and then increase. When the organic silicon content is 1.0% and the rock wool fiber content is 2.0%, the comprehensive performance of ultra-light foam concrete is the best. The pores in ultra-light foam concrete is nearly spherical, and the pore size is 50~1 000 μm, and the pores with different pore diameters are stacked and distributed evenly.
