For laying concrete blocks, use building sand or mason's sand. These sands have smaller, less angular grains than sharp sand, making them ideal for creating strong and durable mortar bonds. Sharp sand, while suitable for other applications like paving, is less suitable for brick and blocklaying due to its coarser texture.
Choosing the Right Sand
The type of sand significantly impacts the quality of your blockwork. Here's a breakdown:
- Building Sand/Mason's Sand: Recommended for brick and blocklaying projects. Its finer, less angular grains create a better bond with the mortar. [Source: Marshalls]
- Sharp Sand: Better suited for concrete work and paving due to its rough texture and excellent binding properties. It's not the best choice for blocklaying. [Source: Unspecified article from Aug 4, 2023]
Choosing the correct sand ensures a strong and lasting structure. Using the wrong type can compromise the integrity of your blockwork.
Sand Specifications
While the above provides general guidance, specific sand requirements may vary depending on your location and building codes. Refer to local regulations and building standards for precise specifications. One resource that provides specifications for masonry sand is IS 2116 (1980): Sand for masonry mortars - Specification.
