Terrazzo flooring is also called ______
🔬 Understanding Terrazzo Flooring
Terrazzo is a composite flooring material made by mixing chips of marble, quartz, granite, glass, or other decorative stones with a binder, which is typically cementitious or polymeric. After it cures, the surface is ground and polished to a smooth, uniform finish, revealing the beauty of the aggregate chips.
The term Grano flooring is often used synonymously with Terrazzo. "Grano" is short for granolithic, which refers to a high-strength concrete made with granite or other hard-wearing aggregates. Because Terrazzo often uses granite chips and results in a similar durable, polished surface, it is also known as Grano flooring.
⚖️ Detailed Analysis of the Options
Let's distinguish between the different types of flooring mentioned.
(b) Granite flooring
Why it's incorrect: Granite flooring consists of solid tiles or slabs of natural granite, an igneous rock. It is not a composite material. While Terrazzo can contain granite chips, it is fundamentally different from a floor made entirely of granite slabs.
(c) IPS flooring
Why it's incorrect: IPS stands for Indian Patent Stone. This is a basic, functional floor finish made from a mix of cement and sand (and sometimes small aggregates), laid over a concrete base. It is a simple, durable surface but lacks the decorative aggregates and high-polish finish characteristic of Terrazzo.
(d) Mosaic flooring
Why it's incorrect: While visually similar, Mosaic and Terrazzo are different. Mosaic flooring is created by arranging small, individual pieces of tile or stone (tesserae) into a specific pattern or design. In contrast, Terrazzo involves a random mixture of chips poured together with a binder.
(a) Grano flooring
Why it IS the correct answer: As explained, "Grano" is short for granolithic. This type of flooring uses hard aggregates like granite chips mixed into a cement binder, which is the exact principle of Terrazzo. Due to this similarity in composition and appearance, Terrazzo is widely referred to as Grano flooring.
📋 Summary of Key Flooring Types
Here is a quick comparison:
- Terrazzo / Grano: A composite of decorative chips (marble, granite) mixed in a binder and polished.
- Granite: Natural, solid stone tiles or slabs.
- IPS: A simple, utilitarian cement-concrete floor topping.
- Mosaic: Small, distinct tiles intentionally arranged to form a pattern.
