No, building sand is not sharp sand. They are different types of sand used for different purposes in construction.
Building sand, also known as soft sand or plastering sand, has fine, rounded grains. This makes it ideal for creating smooth mortars and renders, particularly for bricklaying. The fine texture ensures good workability and a smooth finish.
Sharp sand, on the other hand, has coarser, angular grains. This makes it stronger and more suitable for applications where strength and drainage are important, such as concrete mixes, screeds, and laying paving slabs. The angular grains interlock, providing a robust and durable structure.
Here's a table summarizing the key differences:
| Feature | Building Sand (Soft Sand) | Sharp Sand |
|---|---|---|
| Grain Size | Fine, Rounded | Coarse, Angular |
| Texture | Smooth | Gritty, Sharp |
| Primary Use | Mortar for bricklaying | Concrete, screeds, paving |
| Drainage | Poor | Good |
| Workability | High | Lower |
In essence, builders sand is used where a smooth, workable mix is needed, while sharp sand is used where strength and drainage are paramount. Confusing the two can lead to structural issues and poor results.
