When people choose terrazzo stone, they will be concerned about one question: Is terrazzo stone easy to crack? How long is its service life? This article will explore this issue in depth from multiple angles, and comprehensively answer readers' questions by analyzing the material properties, construction technology, maintenance and other aspects of terrazzo stone.
Material properties of terrazzo stone
To understand whether terrazzo stone is easy to crack, you first need to understand its material properties.
1. Composition
Terrazzo stone is mainly made of a mixture of materials such as cement, sand, gravel, pigments and additives. Its core materials are cement and gravel, which are repeatedly polished and polished to form a hard and dense surface. The structure of this composite material determines that terrazzo stone has high hardness and strength.
2. Physical properties
The hardness of terrazzo stone is usually around 6-7 on the Mohs hardness scale, and the compressive strength can reach 40-60 MPa, with high wear resistance and impact resistance. These excellent physical properties make terrazzo stone perform well in high-intensity use environments and are not easy to crack due to external forces.
Terrazzo stone construction process
The construction process has a vital impact on the overall quality and durability of terrazzo stone.
1. Material mixing
During the production process of terrazzo stone, the mixing ratio of materials must be strictly controlled to ensure the uniformity and stability of the mixture. If the proportion of cement, sand and gravel is improper or the mixing is uneven, it will affect the strength and durability of terrazzo stone and increase the risk of cracking.
2. Pouring and compaction
During the pouring process of terrazzo stone, it is necessary to ensure that the mixture is evenly distributed and fully compacted. Insufficient compaction will cause internal voids and increase the possibility of cracking. At the same time, bubbles should be avoided during the pouring process to ensure the density of the material.
3. Grinding and polishing
Grinding and polishing are important steps in the construction of terrazzo stone. Through multiple grinding and polishing, a smooth and flat surface can be formed to improve the beauty and wear resistance of the material. However, if the grinding and polishing process is not done properly, scratches or uneven areas on the surface will also affect the durability of the terrazzo stone.
What is the reason for the cracking of terrazzo stone?
Although terrazzo stone has high strength and wear resistance, cracking problems may still occur in some cases. Common reasons for cracking are mainly the following:
1. Unstable base
The laying of terrazzo stone requires a stable base. If the base is unstable, such as foundation settlement, ground vibration, etc., it will cause stress to the terrazzo stone and cause cracking. Therefore, before laying terrazzo stone, it is necessary to ensure the stability and firmness of the base.
2. Temperature change
Temperature change is another major cause of terrazzo stone cracking. Cement materials will expand and contract when the temperature changes, especially in outdoor environments, where the temperature difference between day and night is large, it is easy to cause the expansion and contraction of terrazzo stone, resulting in cracks.
3. Construction quality issues
If the material ratio is improper, the compaction is insufficient, and the grinding and polishing are uneven during the construction process, the overall quality of the terrazzo stone will be affected and the risk of cracking will be increased. A professional construction team and strict construction specifications are essential to prevent terrazzo stone from cracking.
4. Overload
Although terrazzo stone has a high compressive strength, it may still crack under overload conditions. For example, in heavy-load environments such as shopping malls and parking lots, if the design load is insufficient or exceeds the design range, the terrazzo stone floor is prone to excessive pressure and cracking.
How many years is the service life of terrazzo stone?
The service life of terrazzo stone is affected by many factors, including material quality, construction technology, use environment and maintenance. Generally speaking, the service life of high-quality terrazzo stone can reach more than 30 years under normal use and good maintenance.
1. Material quality
High-quality cement, gravel and additives are the basis for ensuring the long life of terrazzo stone. Selecting reliable quality materials and strictly controlling the material ratio can effectively improve the durability of terrazzo stone.
2. Construction technology
A professional construction team and strict construction specifications are important guarantees for the quality of terrazzo stone. Through scientific construction technology, ensuring uniform mixing, full compaction and fine grinding of materials, the service life of terrazzo stone can be effectively extended.
3. Use environment
The use environment has an important impact on the life of terrazzo stone. In harsh environments such as high temperature, humidity and vibration, the service life of terrazzo stone may be affected to a certain extent. Therefore, when choosing terrazzo stone, the special needs of the use environment should be fully considered to select suitable materials and construction plans.
4. Maintenance
Good maintenance is the key to extending the service life of terrazzo stone. Daily cleaning, regular waxing, timely repair of cracks and protective treatment can effectively protect the surface of terrazzo stone, delay aging and wear, and ensure its long-term durability.
Conclusion
Through a detailed analysis of the material properties, construction technology, cracking causes, service life and maintenance of terrazzo stone, it can be seen that terrazzo stone is not easy to crack under normal use and good maintenance, and its service life can reach more than 30 years.
