Coarse sand is a type of sand characterized by larger grains and a rough texture, typically ranging from 0.5mm to 2mm in size. Unlike fine sand, coarse sand particles are more angular and irregular in shape, giving them excellent interlocking properties that are crucial for construction applications. Also known as rough sand, grit sand, or concreting sand, coarse sand is an essential component in various construction projects due to its unique properties and versatility.
Particle Size and Composition: Coarse sand features larger particles (0.5-2mm) with an irregular shape that provides superior interlocking capabilities in construction materials. This characteristic makes it ideal for applications requiring strength and stability.
Grain Shape: The angular and rough texture of coarse sand grains allows for better grip and interlocking in concrete and mortar mixtures, resulting in stronger bonds compared to the rounded particles found in fine sand.
Excellent Drainage: The larger grain size of coarse sand creates more space between particles, allowing water to flow through easily. This makes it perfect for applications where proper drainage is essential to prevent water accumulation.
Low Water Retention: Coarse sand has lower water retention properties compared to fine sand, which helps in creating well-draining construction materials.
Permeability: With its larger grains and lower fineness, coarse sand offers higher permeability, making it suitable for projects requiring efficient water drainage.
Resistance to Shrinkage and Cracking: The larger particle size and better bonding properties of coarse sand reduce the likelihood of shrinkage and cracking in concrete and mortar, enhancing the long-term durability of structures.
At ASF Corporation, we supply high-quality coarse sand for various construction applications in Dhaka. Our coarse sand is suitable for:
Coarse sand is a crucial ingredient in concrete mixtures, helping to prevent excessive shrinkage as the concrete cures and reducing the likelihood of cracks developing. When combined with cement, water, and other aggregates, it forms strong concrete that can be used in constructing roads, bridges, buildings, and other infrastructure projects. The large particles provide the necessary compressive strength required for these structures.
Coarse sand is essential for preparing mortar used in bricklaying. It adds strength and texture to the mortar, making it an essential component for laying bricks, blocks, and stones. Its grainy texture allows for better adhesion and bonding between materials, creating stronger and more durable structures.
For construction projects in Dhaka, a solid foundation is critical. Coarse sand is used in foundation construction as layers beneath slabs and footings. Its excellent drainage properties prevent water accumulation and ensure a stable foundation for buildings. It’s also commonly used as a bedding material for pipes and underground cables to provide stability and minimize shifting.
In road construction, coarse sand serves as a stable base layer beneath roadways and pavements. It’s often layered beneath roads and sidewalks to provide a firm foundation that supports the overlying materials like asphalt or concrete and withstands the pressures of daily traffic.
Coarse sand is widely used in landscaping projects due to its excellent drainage properties. It can be used to improve soil drainage and quality, propagate cuttings, make free-draining planting mixes, and create a top dressing for lawns. In Dhaka’s climate with heavy monsoon rains, proper drainage is essential for both construction and landscaping projects.
For backfilling around foundations, trenches, and retaining walls, coarse sand is an excellent choice. Its drainage properties help reduce water pressure on structures, minimizing the risk of damage due to water infiltration-a common concern during Dhaka’s rainy season.

At ASF Corporation, we are committed to responsible sourcing practices that minimize environmental impact.
We work with suppliers who follow sustainable extraction methods and, where possible, incorporate recycled coarse sand into our supply chain. Recycled coarse sand is processed from recovered materials from demolition sites, offering the same strength, cleanliness, and durability as virgin construction sand while reducing environmental impact.
When planning your construction project in Dhaka, it’s important to understand the difference between coarse sand and fine sand to make the right choice:
Coarse sand has larger grains (0.5mm to 2mm) that are irregular in shape and size with a rough texture. It offers excellent drainage due to larger grain size, has low water retention, is generally less expensive, and is primarily used for concrete, mortar, foundations, and drainage applications.
Fine sand, on the other hand, has smaller grains (0.075mm to 0.425mm) that are more even and rounded with a smooth texture. It has poor drainage due to smaller grains, high water retention, is usually more expensive, and is primarily used for finishing work, plastering, and tile work.
The choice between coarse and fine sand depends on your specific project requirements. For applications that need strength and stability, coarse sand is the preferred choice, while fine sand is suitable for smoother finishes and less critical structural elements.
ASF Corporation proudly serves construction companies, contractors, and individual builders throughout Dhaka. Our coarse sand delivery services cover all areas including:

Coarse sand in Bangladesh is characterized by larger grains ranging from 0.5mm to 2mm in size with an irregular shape and rough texture. It typically has a fineness modulus (FM) of around 2.0 and is primarily used for concrete casting work in construction projects throughout the country.
Coarse sand (FM 2.0) has larger particles compared to medium sand (FM 1.5, used for brick masonry) and fine sand (FM 1.05, used for plastering). The particle size distribution affects its applications – coarse sand provides better strength for concrete, while finer sands are used for finishing work and plastering.
Coarse sand is primarily used for:
Coarse sand in Bangladesh is commonly sourced from riverbeds, particularly from the Brahmaputra river. Other sources include rivers in Sylhet, Netrakona, and various hilly rivers. Local sand extraction is regulated to minimize environmental impact.
Key tests for coarse sand quality include:
The fineness modulus indicates the particle size distribution – higher FM values (like 2.0-2.5 for coarse sand) provide better interlocking between particles, resulting in stronger concrete. This makes coarse sand ideal for structural applications requiring high strength and durability.
Yes, different types of sand can be mixed for specific applications, but this should be done with proper engineering guidance. The Bangladesh National Building Code provides guidelines for appropriate mixing ratios. However, sand from different sources should not be mixed and stored in the same stockpile without permission from the engineer.
The construction industry’s demand for sand has significant environmental implications, with an estimated 50 billion tonnes of sand used annually worldwide. Sustainable practices include responsible sourcing, using recycled coarse sand from demolition sites where possible, and following local regulations for sand extraction.
Coarse sand contributes to higher compressive strength in concrete compared to finer sands. Research conducted at Bangladesh Agricultural University found that concrete made with coarse sand (FM 2.5) showed the highest compressive strength, followed by moderately coarse sand (FM 1.8) and fine sand (FM 1.4).
The optimal cement-to-sand ratio depends on the specific application. For general concrete work with coarse sand, ratios between 1:4 and 1:6 are common. Research indicates that a 1:6 mix proportion with moderately coarse sand (FM 1.8) provides the best combination of density, water absorption, compressive strength, and cost-effectiveness for building blocks.
