Regarding the duration and durability of roadside stones . With the development of economic society, roadside stones have entered tens of millions of projects. The protection of roadside stones has become an important operation. If the protection is not timely, it will affect the roadside stones. Age and longevity.
Regarding the service life and longevity of roadside stones, roadside stones have a high position in the guessing of decoration materials, and they have an irreplaceable role. They are generally used on the "door face" of construction projects. Stone and engineering have the same life. The outstanding long-lasting roadside stone can not only guarantee the beautiful construction, but also extend the overall periodicity of the construction.
When the roadside stone is used as the ground and engineering material on the road, the following investigation must be done on the roadside stone:
1, physical; roadside stone must be able to withstand multiple external forces such as gravity, wind, sensation, temperature difference, wear, pressure and other damage. This requires the strength of roadside stones to be high, especially for engineering installations.
2. Chemical property: The stone along the road must have resistance to wind, water, solvent, dehydration, acid, and carbonic acid. To do this, the stone along the road must be waterproof.
3. Structural: When using directional road stones such as marble, pay attention to the strength in different directions.
4. Water absorption: When the roadside stone is not excavated, the structure is relatively stable, but when exposed to the air, the problem of the matching of minerals in the roadside stone occurs, such as when the stone encounters acidic substances (the reaction of sulfuric acid and water in the air) Dissolves in the surface to form calcium sulfate, which causes the collapse of stones. Therefore, when choosing a rock along the road, try to choose a rock along the road with a uniform distribution of holes, small holes, and low water absorption.
