Problems solved by technology

[0003] However, a large amount of coarse aggregate and fine aggregate are required in the preparation process of concrete, which will consume a large amount of natural ore and sand, resulting in natural aggregate Overexploitation, leading to environmental damage
In addition, with the improvement of people's living standards and awareness of energy conservation and environmental protection, the comfort, energy conservation and environmental protection of buildings have also become the focus of people's attention. Various new building materials have entered people's field of vision. Thermal building materials, this kind of building materials often need to add insulation materials during the preparation process, such as polyurethane, asbestos, etc. These raw materials are costly on the one hand, and on the other hand, they are toxic, which affects their use effect

Abstract

The invention discloses an energy-saving and environment-friendly building material and a preparation method thereof. The energy-saving and environment-friendly building material is prepared from, byweight, 20-40 parts of cement, 10-20 parts of excess sludge of sewage treatment plants, 60-80 parts of gravels, 30-50 parts of steel slag powder, 10-20 parts of firmiana catkins, 3-5 parts of tannic acid, 0.5-1 part of ferric trichloride, 0.5-1 part of sodium hexametaphosphate, 0.5-1 part of polyacrylamide, 0.5-1 part of polyvinylpyrrolidone, 0.5-1 part of a water reducing agent and 50-80 parts ofwater. By adoption of wastes as a main raw material for preparing the energy-saving and environment-friendly building material, on the one hand, making use of characteristics of the wastes is realized, and on the other hand, natural fine aggregates and heat preservation materials are substituted, production cost is reduced, and secondary resource development, waste recycling and environmental pollution abatement are realized; in addition, the prepared energy-saving and environment-friendly building material is remarkable in heat preservation effect and has an extensive application prospect.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an energy-saving and environment-friendly building material and a preparation method thereof. Background technique [0002] Materials used in buildings are collectively referred to as building materials, and building materials are collectively referred to as materials used in civil engineering and construction engineering. Concrete is also a kind of building material. It is usually obtained by using cement as the cementitious material, sand and stone as the aggregate, mixed with water in a certain proportion and then stirred. It has the advantages of easy molding, low energy consumption and good durability. Advantages, it is the most widely used building material. [0003] However, a large amount of coarse and fine aggregates are required in the preparation process of concrete, which consumes a large amount of natural ore and sand, which in turn leads to e...
