Granite has a significant advantage in terms of wear and tear during long-term use compared with other commonly used building stones.
1. Hardness and wear resistance
Granite is known for its high hardness, which means it is harder to wear than many other common building stones. The specific performance is as follows:
High hardness: Granite's high hardness makes it resistant to scratches and wear, and it is not easy to get scratches and dents. This makes Granite perform well in frequent human traffic and mechanical contact, and it can still maintain a flat and smooth surface after long-term use.
Wear resistance: Granite has a tight crystal structure, which makes its surface hard and not easy to wear.
2. Compressive strength
Granite has high compressive strength and can withstand greater pressure and impact without breaking or peeling. It is specifically reflected in the following aspects:
High compressive strength: Granite's compressive strength is usually between 120 and 250 MPa, which is much higher than many other stones. For example, the compressive strength of sandstone is usually between 50 and 150 MPa, while the compressive strength of slate is between 50 and 100 MPa.
Impact resistance: Granite has good impact resistance due to its high density and uniform crystal structure. It can withstand the impact and vibration of heavy objects and is suitable for construction parts such as foundations, steps and load-bearing walls.
3. Chemical stability
Granite shows high chemical stability in acidic, alkaline and neutral environments, and is not easily eroded and corroded by chemical substances. Specifically:
Acid and alkali erosion resistance: Granite has good resistance to common acid and alkali solutions, such as sulfuric acid, hydrochloric acid and sodium hydroxide. This is different from marble, which is prone to chemical reactions in acidic environments, resulting in surface corrosion and dissolution.
Weathering resistance: Granite's high-density structure makes it have strong weathering resistance in the natural environment, and is not easily eroded by natural factors such as wind, rain, frost and snow, maintaining a long-term stable appearance.
4. Weather resistance
Granite has excellent weather resistance, can remain stable under different climatic conditions, and is not prone to physical and chemical changes. Specifically, it is:
Freeze-thaw cycle resistance: Granite has good freeze-thaw resistance and is not prone to cracking and peeling due to temperature changes. In contrast, sandstone and slate are prone to freeze-thaw damage in cold areas due to their large pores.
UV resistance: Granite is highly resistant to ultraviolet rays and is not prone to color fading and surface hardening due to ultraviolet radiation. However, some stones (such as some varieties of marble) will gradually turn yellow or fade under long-term ultraviolet radiation.
5. Maintenance and care
Granite is relatively simple to maintain and requires less maintenance work during long-term use. The specific advantages are as follows:
Low maintenance cost: Due to Granite's high wear resistance and chemical stability, its surface is not prone to stains and wear, and cleaning and maintenance work is relatively simple, reducing maintenance costs.
High durability: Granite is more durable than many other stones and can withstand long-term use and frequent cleaning, maintaining long-term beauty and functionality.
In summary, Granite has significant advantages over other commonly used building stones in terms of wear and tear during long-term use. Its high hardness, high compressive strength, excellent chemical stability, weather resistance and low maintenance cost make Granite an extremely durable material in the construction field. Therefore, Granite is undoubtedly an ideal choice in construction scenarios that require wear resistance, pressure resistance, chemical erosion resistance and weather resistance.
