Terrazzo tiles are composed of a mixture of chips and a binding material. The chips, which are the primary decorative component, can be made from various materials such as marble, quartz, granite, glass, or other suitable aggregates. These chips are embedded in a binder, which can be cementitious, epoxy, or a combination of both.
1. **Chips/Aggregates**: The chips are the visible part of the terrazzo and can vary in size, color, and material. Marble chips are the most traditional, but modern terrazzo can include recycled glass, metal, or even mother of pearl for unique effects.
2. **Binder**:
- **Cementitious Binder**: This is a traditional option, using a cement matrix to hold the chips in place. It is durable and suitable for both indoor and outdoor applications.
- **Epoxy Binder**: This is a more modern option, offering a wider range of colors and a thinner, lighter tile. Epoxy terrazzo is typically used indoors due to its sensitivity to UV light.
3. **Pigments**: To achieve the desired color, pigments can be added to the binder. This allows for a wide range of design possibilities, from subtle, natural tones to vibrant, bold colors.
4. **Additives**: Additional materials may be included to enhance the properties of the terrazzo, such as plasticizers for flexibility or sealants for increased durability and stain resistance.
The mixture is poured into molds or onto surfaces, then cured, ground, and polished to achieve a smooth, glossy finish. This process reveals the beauty of the embedded chips, creating a durable and aesthetically pleasing surface.
