Stone

The so-called stone is the material used to make different functions of stone, and the current stone has three main types of stone, pavement stone, stone used in sculpture, stone used in bridges, etc.; these three different functions and performance of stone in the production process of the stone used is completely different, the physical properties of different stone it embodies is also different.

Stone technical standards:

1. Mechanical properties

Mechanical properties refers to the ability of the material to resist the complex force system of vehicle loads. At present, in addition to the static tensile, compression, bending, shear and other tests to reflect the mechanical properties of the material, but also using abrasion, polishing, impact and other tests to reflect its performance.

2. Physical properties

Usually through the determination of the physical constants of the material, such as true density, gross bulk density, void ratio, water content, etc. to understand the internal composition of the material structure, and because there is a certain correlation between the physical constants and mechanical properties, can be used to infer the mechanical properties of the material.

3. Chemical properties

Chemical properties is the performance of the material to resist the chemical effects of various surrounding environments, road and bridge materials in the surrounding media (such as piers in industrial sewage) erosion, will lead to a reduction in strength; in the combined effect of atmospheric factors, will cause the aging of the material, especially a variety of organic materials (such as asphalt materials, etc.) more significant.

4. Process nature

Stone production line process nature refers to the material suitable for processing according to certain process requirements of the performance. For example, cement concrete mix requires a certain degree of compatibility for pouring. Stone production line material process properties are controlled by certain experimental methods and indicators.
