When consumers purchase decorative stone, they can identify their quality from the following:
The commonly used decorative stone for exterior appearance is marble and granite.
In general, the marble has a fine texture, a variety of patterns, a bright color, and is easy to process and polish. However, the hardness is low and the wear resistance is inferior to that of granite. Mainly used for interior floor, wall, window sill and cylinder finishes.
Granite is characterized by its compact structure, low water absorption, hard texture, and high strength. In particular, the compressive strength can reach 1200-2500 kg/cm2. Because granite's main constituent minerals are very resistant to acid, they are extremely resistant to acid corrosion, and alkali-resistant erosions also have strong resistance to corrosion.
Granite is not easily weathered and deteriorated, and the appearance of color can be maintained for more than a hundred years, so it is mostly used for exterior wall decoration. Because it has strong anti-corrosion ability to acid in the air, it is harder than marble and wear-resistant. It is incompatible with marble, terrazzo and other stone materials in durability. Therefore, it is an ideal building decorative natural stone. Compared with marble, granite has fewer changes in color and pattern, but there are more flexible changes in the texture, and at the same time, the overall feeling seems more solemn and classical.
The material of quality stone should be uniform and complete, avoid dark cracks, black defects and color differences.
1. Pay attention to the composition of the stone to avoid excessive iron sulfide, iron oxide, carbon and clay and other harmful substances;
2. Pay attention to the radiation level of the stone;
3. Pay attention to whether the stone contains too high thermal expansion coefficient, thermal conductivity, and conductivity of the mineral composition to avoid the risk of cracks, heat conduction and conduction.
Durability should be selected as possible stone with uniform pore distribution, small pore size, low water absorption, and high hardness and compressive strength. However, attention should be paid to the fact that although the stone with a large specific gravity has a higher strength, it will increase the structural load, and will reduce the strength of the house and the ability to resist earthquakes.
