Abstract

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<3> of fine aggregate, 440 to 520 kg/m<3> of cement, 30 to 45 kg/m<3> of silica fume, 60 to 100 kg/m<3> of admixture, 3.4 to 3.9 kg/m<3> of water reducing agent, 98 to 135 kg/m<3> of running water and 0 to 9 kg/m<3> 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.

Description

technical field [0001] The invention relates to a lightweight concrete exterior wall plate and a production method thereof. Background technique [0002] In my country, the level of building energy conservation is far lower than that of developed countries, and the energy consumption per unit area of ​​buildings is still 3 to 5 times that of developed countries with similar climates; while my country's per capita resources are at an obvious disadvantage in the world, so energy conservation is my country's priority. a basic national policy. [0003] In terms of building energy conservation in China, energy-saving materials with good effects are relatively scarce. The polystyrene board insulation system widely used at present has its inherent shortcomings: 1) The durability is not good, and the design service life of building structures is generally 50 years. The service life of styrene board is only 10 to 15 years, which cannot meet the requirements of the building's service ...
