The so-called stone stone material is used to make different function, and at present there are mainly three types of stone material, used in paving stone, sculpture, used stone, stone used in Bridges, etc.; The three different function and performance of the stone in the process of production of stone is not the same, different stone as reflected in its physical properties are also different.

Stone technology standards:
1. The mechanical properties
Mechanical property is refers to the material a ability of the combined action of vehicle load resistance complicated force system. At present, in addition to static pull, pressure, bending, shear test to reflect the material mechanical properties, also impact abrasion, polishing, such as test to reflect its performance, etc.
2. Physical properties
Usually by measuring physical constants of materials, such as true density, volume density, void ratio, water content and so on to get to know the inner structure of the material and the physical constants and must have correlation between mechanical properties, which can be used to infer the material mechanics performance.
3. The chemical properties of
Against a variety of environment for its chemical property is the material chemistry performance, road and bridge materials in by the surrounding medium (such as bridge pier) in the industrial wastewater of erosion, can reduce the strength; In combination by atmospheric factors, can cause the aging of materials, especially all kinds of organic materials (such as asphalt material, etc.).
4. The process characteristics
Stone production line nature refers to the material suitable for according to certain technical requirements and processing performance. For example, the workability of concrete mixture needs certain, so that the casting. Stone production line material nature of the process is controlled by certain experimental methods and indexes.
