What are the commonly used types of building engineering materials?

Wood is a lignified tissue, which is formed by plants that can grow twice, such as trees and shrubs. After the primary growth of these plants, the vascular cambium in the roots began to move, developing phloem outward and wood inward.

2. Cement

Cement is a kind of powdery hydraulic inorganic cementing material. Mud can be hardened in air or water after being mixed with water, and can firmly bond sand, stone and other materials together.

3. Stone materials

As a high-grade building decoration material, it is widely used in indoor and outdoor decoration design, curtain wall decoration and public facilities construction. At present, the common stones in the market are mainly divided into natural stones, artificial stones and marble.

4. Composite materials

Glass is a new type of material, which is made of different material components by using advanced material preparation technology. The matrix materials of composite materials can be divided into two categories: metal and nonmetal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and their alloys. Non-metallic matrix mainly includes synthetic resin, rubber, ceramics, graphite, carbon and so on.

5. Glass

Glass is an amorphous inorganic nonmetallic material, which is generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.). ) as the main raw material, and add a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides.
