1. Natural material, bright and shining, hard and permanent, noble and elegant;
2, frost resistance: stone in the wet state, can resist freezing and thawing without significant damage, this performance is called freeze resistance. The water in the pores of the rock freezes when the temperature is as low as minus 20 degrees Celsius, and the water expansion in the pores is 1/10 larger than the original volume. If the rock cannot resist the force generated by the expansion, the damage will occur;
3, compressive strength: the compressive strength of stone will be different due to factors such as mineral composition, crystal thickness, uniformity of cemented material, load area, load and cleavage angle. If other conditions are the same, a dense material in which the crystal grains are fine and bonded to each other generally has a high strength.
