Frequently Asked Questions
What is filling sand and what is it used for?
Filling sand is a crucial component in construction applications, serving as the foundation for buildings, roads, and infrastructure projects. It’s characterized by its larger grain size and lower silt content, making it ideal for applications where drainage and stability are paramount. It’s specifically selected for its compaction properties and ability to provide stability to construction sites.
What are the quality requirements for filling sand in Bangladesh?
According to Bangladesh construction standards, filling sand should be silty sand or other approved materials that are free from large lumps, organic matter, or other extraneous materials. For proper construction, the sand should have a fineness modulus (FM) not less than 1.0 and should be clean and free from organic and deleterious materials.
How is filling sand properly installed in construction projects?
Filling sand should be deposited and spread in successive uniform horizontal layers of about 150mm thickness. It should be compacted using mechanical equipment such as a 1.5-ton “Vibro” compactor to achieve 98% standard dry density in road and pavement sub-base and 95% standard dry density for other areas. Proper compaction is essential for structural stability.
What types of sand are available in Bangladesh for construction?
There are three main types of sand used in Bangladesh for construction:
- Local Sand/White Sand (fine, medium, and coarse varieties)
- Sylhet Sand/Red Sand
- River Sand
Each type has different properties and applications in construction work.
What is the difference between fine, medium, and coarse sand?
- Fine Sand (সরু বালি): Has very small-sized grains with a fineness modulus (FM) of 1.05 and is primarily used for plastering.
- Medium Sand (মধ্যম বালি): Has an FM of 1.50 and is generally used for making mortar for brick masonry.
- Coarse Sand (মোটা বালি): Has an FM of 2.00 and is used in concrete casting work.
How do I determine the quality of filling sand for my construction project?
Quality filling sand can be determined through several tests:
- Fineness Modulus (FM) test (standard value for local sand is 1.2 to 1.8)
- Unit weight test (standard value is approximately 1600 kg/m³)
- Specific gravity test (allowable specific gravity is around 2.5)
- Absorption capacity test
- Salinity test to ensure there’s no salt content that could affect construction
Can I use excavated soil from my construction site as filling material?
Materials from excavation on construction sites may be used as ordinary fill if approved by the engineer. However, the material must meet the required specifications for filling sand, being free from large lumps, organic matter, or other extraneous materials. Tests should be conducted to ensure the material meets the necessary quality standards.
What precautions should be taken when filling against a newly constructed structure?
When filling or backfilling against a newly constructed structure, precautions must be taken to ensure the structure is well matured to take the thrust of filling. When filling against a wall, the filling should be done from both sides simultaneously to prevent uneven pressure that could damage the structure.
What is sand pile construction and when is it used?
Sand pile construction is used to improve the stability of the ground with greater strength and stiffness. It’s particularly useful in areas with poor soil conditions. Sand piles are installed by driving casings into the ground and filling them with compacted sand. This technique is cost-effective, durable, and reliable for enhancing ground stability before construction.
How does the quality of filling sand affect the overall construction?
The quality of filling sand directly impacts the structural integrity and longevity of construction projects. Poor quality sand can lead to settlement issues, inadequate drainage, and structural instability. Using sand with the proper fineness modulus, free from organic matter and with good compaction properties ensures a stable foundation, proper load distribution,
