1. Natural material, bright crystal, hard permanent, noble and elegant

2. Frost resistance: stone in the wet state, can resist freezing and thawing without significant damage, this performance is called frost 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 this expansion, it will be damaged.

3. Compressive strength: The compressive strength of the stone will vary due to factors such as mineral composition, crystallization thickness, uniformity of the cementing material, load area, load action and cleavage Angle. If other conditions are equal, usually the crystalline particles are small and bonded to each other dense materials, with high strength.
