Characteristics and Applications of Cave Stones
Cave stone, also known as limestone, has a core component of calcium carbonate.
　
The Natural Formation and Characteristics of Cave Stones
Cave stones, a natural wonder known as the bottom of the sea or lake, cannot be formed without specific environments. At the bottom of the sea or a large lake, due to weak hydrodynamic forces, hot springs that emerge from underground can flow smoothly, allowing the calcium carbonate in them to settle evenly and create exquisite patterns. These patterns are not only unique and full of charm, but also the secret of cave stones becoming natural artworks.
　
Although cave stones are beautiful, there are inevitably some shortcomings. One of them is the bending problem, which is mainly caused by external interference when hot springs emerge. In addition, the colors of cave stones are also quite diverse, with the mainstream color being light beige. However, there are also various options available in the market, such as yellow cave stones, coffee cave stones, ultra white cave stones, red cave stones, and gray cave stones.
　
Processing and Decorative Characteristics of Cave Stones
The gentle texture and rich texture of cave stones inject profound cultural heritage and historical charm into the decorated buildings.
　
1. Cave stones have uniform lithology and moderate hardness, making their mining and processing easy.
　
2. Cave stones are not only easy to process, but also have good sound and heat insulation properties, providing a broad space for deep processing applications.
　
3. The texture of the cave stone is tight and delicate, with strong processing adaptability and moderate hardness, making it easy to carve.
　
4. Cave stones come in a variety of colors and have unique textures, and their unique pore structure adds to the decorative effect.
　
5. Cave stone, as a type of marble, is suitable as the main material for exterior walls and is often used as an interior decoration material, providing designers with an ideal choice for consistent interior and exterior design.
　
Restrictions on the use of cave stone curtain walls
Although cave stones are easy to process, their low strength, loose texture, and tendency to accumulate water in the holes result in poor frost resistance and weather resistance. During transportation and installation, some low strength cave stones may even break or shatter. Therefore, when selecting and using cave stones, special attention should be paid to their physical properties and transportation methods.
　
Given the physical properties of cave stones, including their strength, texture, and pore structure, it is necessary to clarify their scope of application and usage limitations when using cave stone curtain walls to ensure their safety and stability.
　
1. Due to its unique physical characteristics, the use of cave stone curtain walls in specific situations requires extra caution. For example, the exterior walls of schools, kindergartens, daycare centers, hospitals, and buildings where the elderly reside should not use cave stones to ensure environmental safety and stability.
　
2. For buildings with high personnel mobility such as shopping malls, train stations, airports, exhibition halls, theaters, and office buildings, the use of cave stone curtain walls should also be carefully selected. In these places, the safety and stability of cave stone curtain walls are crucial, so special attention should be paid to their scope of application and usage restrictions when choosing.
　
3. The cave stone curtain wall should not be used directly facing the outer wall of the T-shaped intersection road.
　
4. Cave stone curtain walls are also not suitable for use on the exterior walls of high-rise or super high-rise buildings.
　
5. In areas with severe pollution, acid rain, and marine environments, the use of cave stone curtain walls also requires caution.
　
6. Cave stone materials are not suitable for use in cold, extremely cold, or environments with significant annual temperature differences.
　
7. When cave stones are used for exterior walls, it should be ensured that the area of a single cave stone is smaller than that of granite, and the long and short sides of its size should be carefully designed according to the texture characteristics of the cave stone.
　
8. When connecting the cave stone and steel skeleton, it is necessary to fully consider the relatively weak strength of the cave stone edge to ensure the stability of the connection.
