What materials do building materials include?

Building materials can be divided into structural materials, decorative materials and special materials.

1, structural material

Based on mechanical properties, structural materials are used to manufacture stressed members. Of course, structural materials also have certain requirements for physical or chemical properties, such as luster, heat conduction, radiation resistance, corrosion resistance and oxidation resistance. Structural materials include wood, bamboo, stone, cement, concrete, metal, brick, ceramics, glass, engineering plastics, composite materials and so on.

2. Decorative materials

Building materials and products used to decorate various civil buildings to improve their use function and beauty and protect the stability and durability of the main structure under various environmental factors. Decorative materials include various paints, coatings, coatings, veneers, various tiles, glass with special effects, etc.

3. Special materials

Special materials refer to materials used for waterproof, moisture-proof, anti-corrosion, fire prevention, flame retardant, sound insulation, heat insulation, heat preservation and sealing.

Classification of decorative materials

1、? Floor decoration material

The commonly used cement mortar floor has good wear resistance and the widest application, but it has the disadvantages of poor sound insulation, inelastic and high thermal conductivity.

2. Interior wall decoration materials

The traditional method is to brush lime water or wall powder, but it is easy to pollute and cannot be scrubbed by wet method, so it is often used in general buildings.

3. Exterior wall decoration materials

Commonly used are cement mortar, crushed fake stone, water brush stone, glazed tile, ceramic mosaic, paint, white cement slurry and so on. Paint, polymer cement mortar, polypropylene fiber, asbestos cement board, inorganic cement foam insulation board, FTC self-adjusting phase change energy-saving material, glass curtain wall, aluminum alloy products and other new exterior wall decoration materials are being adopted in some projects.
