Different Types of Sand Used in Construction
Published on: April 26, 2024
Sand is a versatile material used in many construction projects. It is an integral ingredient in concrete, mortars, and plasters, among other applications. The type of sand used can affect the strength, workability, and finishing of the construction. This article delves into the different types of sand used in construction, examining their properties, applications, and benefits.
1. River Sand (Natural Sand)
Properties: It is obtained from the banks and beds of rivers and streams. This sand is smooth and round in shape due to the natural erosion of water over time.
Applications: Widely used in plastering and concrete works due to its good workability and bonding.
Benefits: Being natural, it is devoid of harmful salts and organic impurities, ensuring stronger bonding in concrete and plaster.
2. Pit Sand (Coarse Sand)
Properties: It’s a coarse type of sand with angular particles and is reddish or orange in color. It’s typically obtained from deep pits.
Applications: Mostly used for concreting and masonry work.
Benefits: Its rough texture provides better bonding with cement.
3. M-Sand (Manufactured Sand)
Properties: Produced by crushing hard granite stones. It is cubical in shape and has grounded edges.
Applications: Used as a substitute for river sand in construction activities. Suitable for plastering, concrete, and brick/blockwork.
Benefits: Offers consistent quality, reduces the dependency on natural sand, and is cost-effective.
4. Concrete Sand
Properties: Also known as sharp sand, it is usually coarse and made from crushed stones.
Applications: Primarily used in the production of Ready-Mix Concrete and asphalt mixing.
Benefits: Provides strength and binds well with cement.
5. White Sand (Beach Sand)
Properties: It’s a fine, white, and smooth sand with rounded particles.
Applications: More suitable for decorative purposes like in gardens, playgrounds, or golf bunkers. Not typically used for construction due to its fine grain and high salt content.
Benefits: Aesthetically pleasing and can enhance the visual appeal of specific landscapes.
6. Fill Sand
Properties: A combination of coarse to fine sand particles.
Applications: Mainly used for leveling or filling large areas.
Benefits: Provides a stable base for construction.
7. Utility Sand
Properties: Also referred to as fill sand, it is somewhat coarse and has multiple grain sizes.
Applications: Often used as a base material for laying foundations, paving, and to fill trenches.
Benefits: It’s cost-effective and offers good compaction.
Conclusion
The type of sand chosen for a particular construction project depends on the requirements of the job. Some sands offer better compressive strength, while others offer aesthetic value or improved workability. Understanding the properties and benefits of each type of sand ensures that builders and contractors select the right material for the task at hand, leading to more durable and long-lasting structures.
