Decoration and heat preservation integrated light-weight concrete plate and production method thereof

The invention discloses a decoration and heat preservation integrated light-weight concrete plate and a production method thereof. The plate is formed by compositing a decoration concrete surface layer and a microhole concrete heat isolation layer, wherein the decoration concrete surface layer consists of the following raw materials according to the weight ratio based on every cubic meter of concrete: 2,100 to 2,400 kg/m of fine aggregate, 440 to 520 kg/m of cement, 30 to 45 kg/m of silica fume, 60 to 100 kg/m of admixture, 3.4 to 3.9 kg/m of water reducing agent, 98 to 135 kg/m of running water and 0 to 9 kg/m of inorganic paint. The decoration and heat preservation integrated light-weight concrete plate is high in heat isolation performance, has natural decorative lines on the surface and has effects of light weight, heat isolation, energy saving, decoration and durability and can be sawed and nailed; and the decoration and heat preservation integrated light-weight concrete plate is a first choice of a wall body material of an energy-saving building.
