Key Features SNL Graded Standard Sand ASTM C778 France

1. High-Purity Silica: The sand contains at least 98% silica (SiO₂), which delivers consistent and interference-free test results for cement strength evaluation.
2. Strictly Controlled Grading: The particle size distribution follows ASTM C778-3 (2021), and SNL uses EN 933-1 to determine and verify grading for every production batch.
3. Rounded, Uncrushed Grains: The natural, uncrushed, rounded grain shape mimics real-world conditions and ensures reproducible mortar workability in test specimens.
4. Ultra-Low Moisture Content: The water content stays below 0.1%, which eliminates moisture-related variability from cement test results.
5. Batch Certificate Included: SNL issues a data control certificate for each delivery, giving laboratories complete traceability and compliance documentation.
6. Standardized Packaging: Each 25 kg bag arrives in a reinforced cardboard box. Pallets hold 2 to 40 bags under plastic covers, making handling and storage straightforward.
7. ASTM C109 Ready: Laboratories can use this sand directly for ASTM C109 compressive strength tests on hydraulic cement mortars without any preprocessing.
8. Proven French Source: SNL sources the raw sand from natural French coastal deposits, which have a well-documented and consistent geological composition.
9. Long Shelf Life: The low moisture and sealed packaging allow long-term storage without degradation of the grading or purity characteristics.

 

Applications SNL Graded Standard Sand Price in Bangladesh

1. Hydraulic Cement Compressive Strength Testing (ASTM C109): Laboratories prepare standard mortar specimens using this sand to measure the 28-day compressive strength of Portland cement and blended cements.
2. Air Content Testing of Mortar (ASTM C185): Quality control labs use the graded sand to prepare mortar mixes for air content measurement and cement air-entraining evaluation.
3. Cement Flow Table Testing (ASTM C230): Engineers use this standardized sand to produce mortar for flow table consistency tests on freshly mixed cement.
4. Calibration of Laboratory Testing Equipment: Testing apparatus, including mixers and flow tables, require periodic calibration using standardized mortar made from ASTM C778 sand.
5. Construction Material Quality Assessment: Quality assurance teams at cement factories and batch plants use this sand to assess incoming cement raw material batches.
6. Research and Development Laboratories: University research departments and materials science labs use ASTM C778 graded sand to develop and validate new cementitious materials.
7. Regulatory Compliance and Third-Party Testing: Certification bodies and third-party inspection agencies conduct independent verification tests using this sand to comply with international standards.
8. Concrete Admixture Testing: Admixture manufacturers test the performance of chemical admixtures (plasticizers, retarders, accelerators) in standard cement mortar made with this sand.
9. Cement Plant Internal QC Laboratories: In-house cement factory laboratories run daily production quality checks using SNL Graded Sand to maintain product consistency.
