Abstract

The invention discloses a method for preparing an aerogel composite sandstone plate with construction waste as an aggregate and industrial solid waste as an admixture. According to the invention, a bottom material, an intermediate material and a surface material are prepared; the sandstone plate is then prepared; and de-molding, curing and surface treatment are carried out. According to the method, construction waste is adopted as the aggregate, such that good economic and social benefits are both provided. With the doped industrial solid waste, the workability of a slurry and the comprehensive performance of the sandstone plate are improved. The prepared aerogel composite sandstone plate has the decorative effect of a sandstone plate, and has certain thermal-insulation performance. In use, the thickness of a housing thermal-insulation layer can be reduced, and housing actual usable area can be effectively improved.
