Decorative concrete is usually divided into two categories: plain concrete and reinforced concrete. Plain concrete is a mixture of cement, sand, stone and other raw materials, without reinforcing materials such as steel bars, and its structural performance is weak. Reinforced concrete is a mixture of cement, sand, stone, steel and other raw materials, which has high structural performance and bearing capacity.
Types of decorative concrete
Fair-faced concrete: Fair-faced concrete refers to the concrete that is cast in one step by directly using the natural color of cast-in-place concrete as a veneer without any external decoration. The main influencing factors of its decorative effect are natural uneven color difference and surface texture.
In specific applications, fair-faced concrete can be divided into decorative fair-faced concrete and architectural fair-faced concrete. After decorative fair-faced concrete is poured, the natural state of cast-in-place concrete is directly used as the facing without external decoration. After building fair-faced concrete is poured, some necessary decoration and protection are needed to achieve the unity of use function and beauty.
Transparent concrete
Light-transmitting concrete: Light-transmitting concrete is a new type of concrete material, which is light-transmitting and allows light to pass through concrete, showing a unique visual effect. Light-transmitting concrete is a new concrete material composed of special aggregate and transparent resin. It has the characteristics of high strength, high light transmittance and high wear resistance, and is widely used in architectural decoration, garden landscape and other fields. The light-transmitting principle of light-transmitting concrete is that the transparent resin particles inside it can let light pass through and make the concrete surface appear transparent. At the same time, the strength and wear resistance of light-transmitting concrete are also well guaranteed.

Colored concrete: The color diversity of concrete is realized by adding pigments or colored stones. This material is suitable for indoor and outdoor floors and walls, and can create a warm and lively atmosphere.
Exposed stone concrete: through special treatment technology, some aggregates are exposed on the concrete surface, forming a unique texture effect. Exposed concrete is mostly used for outdoor floors and steps, giving people a rough and natural feeling.
Stone-like concrete: Imitate the texture and color of natural stone to make concrete have the effect of stone-like. Stone-like concrete is suitable for all kinds of architectural decoration, such as external walls and landscape walls.
Terrazzo concrete: Mix stones of various colors and textures with concrete to form a texture similar to terrazzo. Terrazzo concrete is mostly used for indoor floors and walls, giving people a noble and elegant feeling.

The advantages of decorative concrete are as follows:
Strong decoration: decorative concrete is rich in color, texture and texture, and can produce various appearance effects, such as imitation stone, imitation wood and imitation metal. Good durability: decorative concrete has good durability and corrosion resistance, and can maintain its decorative performance and service life for a long time.

Good environmental protection: decorative concrete can reduce the consumption of natural resources, and its waste can also be recycled.
Good energy saving: decorative concrete has good thermal insulation performance, which can reduce building energy consumption.
However, decorative concrete also has some disadvantages:
Construction difficulty: The construction of decorative concrete needs a high technical level and a professional construction team, otherwise it is easy to have quality problems and appearance defects.
High cost: The material cost and construction cost of decorative concrete are high, so its comprehensive cost is also high.
Maintenance difficulty: the appearance of decorative concrete is easily affected by environmental factors, such as pollution and climate change, and needs regular maintenance.
