Energy-saving brick prepared on basis of building waste and preparation method thereof

Abstract

The invention discloses an energy-saving brick prepared on the basis of building waste. The energy-saving brick is prepared from the following raw materials in parts by weight: 32 to 36 parts of modified building waste, 24 to 28 parts of modified flay ash, 14 to 18 parts of coal gangue, 12 to 14 parts of lithium bentonite, 8 to 12 parts of cotton fiber, 6 to 10 parts of wood fiber, 8 to 12 parts of glass beads, 8 to 12 parts of crushed crude pearlite, 4 to 6 parts of water reducers, 3 to 5 parts of anti-foaming agents, 3 to 5 parts of cement and 1 to 3 parts of filling materials. The inventionaims at providing the energy-saving brick prepared on the basis of building waste. The energy-saving brick has the advantages that the building waste is sufficiently utilized; meanwhile, the properties such as the intensity, the sound isolation and heat isolation performance and the like of the brick can be improved; high use value and good application prospects are realized.

Description

technical field [0001] The invention relates to the field of energy-saving bricks, in particular to an energy-saving brick prepared based on construction waste and a preparation method thereof. Background technique [0002] At present, large-scale economic construction is being carried out in China, especially the construction of new countryside. House demolition and house construction are often carried out. A large amount of construction waste is generated during house demolition. Particles, dust, etc. will cause environmental pollution, and bricks can be prepared by using abandoned buildings; bricks are artificial small blocks for construction, divided into fired bricks (mainly clay bricks) and non-fired bricks (lime sand bricks, fly ash bricks) etc.), commonly known as bricks, clay bricks are made of clay (including shale, coal gangue and other powders) as the main raw material, which is processed, shaped, dried and roasted by mud; according to the material: clay bricks, ...

[0003] Chinese patent document "(Application No.: 201210373050.5)" discloses a fire-free attapulgite construction waste insulation brick. Composed of pyroclastic rock mixture, montmorillonite tailings, diatomite tailings and cement, although the brick uses construction waste as raw material to utilize its resources, it simply mixes construction waste with other raw materials to achieve strength, sound insulation thermal performance can not be effectively improved
