What are the characteristics of natural stone?
Natural stone compressive strength
The compressive strength of the stone will vary depending on the mineral composition, the thickness of the crystal, the uniformity of the cemented material, the area of the load, the load and the angle of the cleavage. If the other conditions are the same, the crystalline particles are usually compact and bonded together with each other, with a higher strength.
Natural stone has good fire resistance
Due to the difference in the type of stone, stone fire resistance is different. However, in general, the fire resistance of stone is very good.
Stone will also expand and shrink
Stone also has the characteristics of thermal expansion and contraction, but the stone in the heat after the cooling, its contraction effect is not so ideal before.
Natural stone has good resistance to freezing
To minus 20 degrees Celsius, the occurrence of freezing, pore water expansion than the original volume of one-tenth of the rock if it can not resist the power of such expansion, there will be damage.
