Problems with Terrazzo in Practical Applications

Terrazzo, a popular building material, may encounter some problems in practical applications despite its aesthetic appeal. Here are some common issues and their possible causes:

1. Corrosion Issues

• Phenomenon: Terrazzo floors are corroded by urine at urinals.

• Cause: Urine contains salts and ammonia, which can chemically react with components in terrazzo, causing corrosion.

2. Color Difference Issues

• Phenomenon: Inconsistency in color among terrazzo slabs in the same space.

• Cause: Variations in cement batches and natural stone aggregates can lead to color differences in terrazzo.

3. Yellowing Issues

• Phenomenon: Terrazzo yellows due to sunlight exposure.

• Cause: Ultraviolet rays may cause photochemical changes in some components of terrazzo, leading to yellowing.

Types and Characteristics of Terrazzo

Inorganic Terrazzo

• Definition: Made from inorganic materials, without resins, glues, or other organic components.

• Advantages: Perfectly matches with cement, no color difference, and environmentally friendly.

• Disadvantages: High water absorption rate, prone to dirt, and requires professional care to form a protective layer.

Organic Terrazzo

• Definition: Terrazzo made with epoxy resins or other organic binders.

• Advantages: May have better integrity and water resistance.

• Disadvantages: May contain organic compounds and is less environmentally friendly than inorganic terrazzo.

Improvement Directions

1. Enhance Chemical Resistance: Improve terrazzo formulations to be more resistant to chemical corrosion.

2. Strictly Control Raw Materials: Ensure consistency in cement and aggregate batches to reduce color differences.

3. UV Protection Treatment: Apply UV protection treatments to terrazzo to reduce yellowing.

Conclusion

The beauty and durability of terrazzo largely depend on its manufacturing process and the quality of raw materials. By improving formulations and processing techniques, the chemical resistance and aesthetics of terrazzo can be enhanced, reducing problems in practical applications.
