Color concrete is a kind of waterproof, antiskid and anticorrosive green decoration material. It is added a layer of colored concrete (decorative concrete) on the dry cement ground, and then it is pressed on the cement ground with a special mold. Color concrete can make the cement ground with all kinds of color, pattern and texture, simulate natural material and texture, draw all kinds of patterns, and the longer it is new, it makes people easy to realize the ideal of building and human environment, harmony and integration of natural environment.

In early 1920s, some people at home and abroad have studied the direct production of ordinary cement and concrete to make decorative materials, such as the practice of prefabricating the surface of concrete blocks into natural mushrooms. In 1940s, people began to develop colored concrete, making the original grey concrete become a variety of colors, and the color decoration concrete developed rapidly. After 1970s, with the development of economy, technology and society, all kinds of decorative concrete are constantly emerging, and are popularized and applied in engineering, and gradually from middle and low grade buildings to high grade buildings.

With the trends, the proportion of the application of decorative concrete has been increasing quickly in the architectural decoration, especially in the external wall decoration of buildings. With the continuous improvement of the quality and performance of decorative concrete, the application of decorative concrete will be more and more extensive.

Decorative concrete is a combination of decoration and function, structure construction and decoration at the same time, making full use of the plasticity of concrete and the composition of the material, taking appropriate measures when the walls and components are formed, so that the surface has decorative lines, patterns, texture, texture and color to satisfy the building in the decorating side. Therefore, decorative concrete is also known as "architectural concrete" and "visual concrete".

With the continuous development of building decoration technology, the understanding of decorative concrete has gradually changed. Decorative concrete mainly refers to white concrete and colored concrete. For these two decorative concrete, the United States, Russia, Japan and other countries have carried out a lot of experimental research and achieved great success. The experimental study shows that the raw materials used in white concrete and color coagulation are basically the same, and the color concrete is different from white cement and white aggregate, and color aggregate and color pigment are also used. Most of the pigments used are red, yellow, brown, blue, green and so on.

DTS diamonds supply a wide range of diamond tooling for color concrete and decorative concrete.
