Sand is one of the most commonly used materials in the construction industry.
Even though it looks simple, sand plays a crucial role in ensuring the strength, stability, and durability of buildings.
What Is Sand?
Sand is a granular material composed of tiny rock particles. It is formed naturally through the process of weathering and erosion over thousands of years.
Main Functions of Sand
1. Mixing Mortar and Concrete
Sand is a key ingredient in making mortar (cement + sand + water) and concrete (cement + sand + gravel + water).
It helps create a solid and stable mixture.
2. Increasing Strength
Sand strengthens mortar and concrete by reducing shrinkage and preventing cracks when the mixture dries.
3. Leveling and Filling
Sand is used to create level surfaces before laying tiles, paving blocks, or foundations.
4. Providing Stability
In construction, sand is used as a base layer for foundations, floors, and road construction to provide stability and prevent sinking.
5. Used for Plastering Walls
Fine sand mixed with cement is used to plaster walls, giving them a smooth, even finish.
Why Sand Is Important
Without sand, mortar and concrete would not form properly. Sand ensures that buildings have strong structures and smooth finishes.
