Manufactured sand, commonly referred to as M sand, is considered a viable alternative to river sand in construction activities for various reasons. Here are some reasons why M sand is often considered better than river sand:
- Consistent Quality: M sand is produced using specialized equipment, ensuring consistent particle size and quality. In contrast, the quality of river sand can vary due to factors like extraction methods and location.
- No Impurities: M sand is free from impurities such as silt, clay, and organic materials, which may be present in river sand. The controlled manufacturing process of M-sand allows for better quality control.
- Eco-Friendly: The extraction of river sand can have adverse environmental impacts, including habitat disruption and riverbed erosion. M sand is produced through crushing rocks or boulders, reducing the environmental impact associated with sand extraction from riverbeds.
- Availability: River sand sources are finite, and excessive mining can lead to depletion. M sand production can be controlled and scaled up as needed, providing a more sustainable and reliable source of sand.
- Grading Zone: M-sand can be manufactured to meet specific grading requirements, making it suitable for various construction purposes. This allows for flexibility in choosing the right type of sand for specific applications.
- Shape and Texture: M-sand can be produced with controlled particle shapes and textures, making it suitable for use in concrete mixes. The angular and rough surfaces of M-sand particles contribute to better bonding with cement.
- Cost-Effective: In some regions, the cost of M sand may be more competitive than river sand due to transportation and availability factors. It can be a cost-effective option for construction projects.
- Usage in Concrete: M-sand is often preferred in concrete production as it can help achieve higher compressive strength and durability compared to river sand.
Despite these advantages, it’s essential to consider local factors, project requirements, and availability when choosing between M sand and river sand. Both have their unique characteristics, and the suitability depends on the specific needs of the construction project.
