Abstract
The invention discloses a method for preparing an aerogel composite sandstone plate by using snowflake white quartz sand as aggregate and industrial solid waste as an admixture. The method includes the steps of preparing a bottom material, a middle material and a surface material firstly; then preparing a sandstone plate; conducting demoulding and curing and surface treatment. Since the snowflake white quartz sand is adopted as the aggregate and the industrial solid waste (fly ash and silica fume) is adopted as the admixture, the use amount of cement can be reduced, and mixability and comprehensive strength of the cement are improved; the prepared aerogel composite sandstone plate not only has the decorative effect of the sandstone plate, but also has certain temperature-keeping and thermal-insulation properties, thickness of a temperature-keeping layer in a house is reduced when the aerogel composite sandstone plate is in use, and actual use area of the house is effectively increased.
