A high position in the decorative stone materials, but also has an irreplaceable decorative, widely used on the building of “window dressing”, so the owners are hoping the building of stone with the same vitality. It has good durability of stone, not only to ensure the beauty installed outside the building, but can be extended refurbishment cycle of a building. So make as there are landscaping stone walls and floor and decoration materials hall, you must do the following aspects of the stone of study:
1, the physical properties of the stone must be able to withstand including gravity, wind off, vibration, temperature changes damage, wear, load and many other external forces. This requires a variety of stone to high intensity, especially high-mounted stone.
2, the chemical properties of the stone tile must have considerable resistance to weathering, hydration, dissolution, dehydration, acidification, reduction and carbonate chemical attack. To do this we must let the stone waterproof.
3, the structural strength of the stone in the selection of directional such as: slate, shale, must pay attention to its structural strength in different directions.
4, water absorption of stone was mined at the end of the molecular structure is relatively stable, but when exposed to the atmosphere, took place between bad fit inside the stone minerals, such as limestone with acid (sulfurous acid gas in the air reacts with water substance) was dissolved table form calcium sulfate, resulting in the collapse of the sandstone and the like. Therefore, should try to choose the stone selected as the stone pore distribution, small aperture, low water absorption.
