About Specific Gravity and Water Absorption of Aggregates
Specification:
Specific Gravity Frame is used in conjunction with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates. The buoyancy balance system consists of a rigid support frame, incorporating a water tank mounted on a platform. A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance. The balance supplied may also be used as a standard weighing device, thus providing a versatile and comprehensive weighing system in the laboratory

FAQ's of Specific Gravity and Water Absorption of Aggregates:
Q: How does the Specific Gravity & Water Absorption Testing Kit operate?
A: The kit operates manually, using a pycnometer to measure aggregate specific gravity and water absorption. The aggregate sample is oven-dried and weighed, then tested in the pycnometer according to IS 2386 (Part III) 1963 procedures. No power or automated controls are required.
Q: What accessories are included with the kit?
A: The kit includes a pycnometer jar (borosilicate glass or polycarbonate), a measuring beaker, and, where specified, a weighing balance. Note that an oven for drying samples is required but not included.
Q: When should the instrument be calibrated?
A: Annual calibration is recommended for reliable results. Calibration ensures continued accuracy and compliance with testing standards for aggregate analysis.
Q: Where can this kit be used in aggregate testing?
A: Ideal for civil construction labs, testing agencies, and educational institutions in India, the kit is designed for table-top or laboratory bench mounting and does not require a power supply, making it versatile for various settings.
Q: What is the recommended sample quantity and specimen size for each test?
A: Each test should be conducted with approximately 1 kg of aggregate, with specimen sizes ranging from 10 mm to 40 mm, ensuring representative results for both specific gravity and water absorption measurements.
Q: What benefits does this testing kit offer for aggregate analysis?
A: This kit offers high accuracy (0.01), instant manual measurement, easy cleaning, corrosion resistance, and robust build quality. Compliance with IS standards ensures trustworthy results and enhanced confidence in construction material selection.
Q: What is the cleaning method for the pycnometer and accessories?
A: All components are washable and resistant to most chemicals. After testing, they can be cleaned with appropriate laboratory detergent and rinsed thoroughly, maintaining long-term usability and accuracy.
