Coarse Aggregate Density Test Set
Product Code : LSK-CL-10590
Coarse Aggregate Density Test Set (SKU LSK-CL-10590) brings together a buoyancy balance, water tank and wire-mesh density basket for finding the density and specific gravity of coarse aggregate by weighing it in air and in water. It handles aggregate between 63 mm and 5 mm. Concrete technology and highway materials labs use it for mix design data. The set is available to institutions, tender contractors and distributors from Science Lab Supplies in Ambala, India.
Specifications
Balance, tank, basket and sieve data for this buoyancy set have separate rows. In short, an 8000 g buoyancy balance hangs a 203 x 203 mm wire-mesh basket by a suspension hook into a water tank of about 400 x 400 x 330 mm, while an 8 inch No. 4 brass sieve and a pan prepare the sample.

Applications and Experiments for the Coarse Aggregate Density Test Set
The set is used to measure the density and specific gravity of coarse aggregate by buoyancy weighing. These values feed directly into concrete mix design, so the test is a routine practical in civil engineering concrete technology and highway materials labs and in construction-materials training courses.
- B.Tech / B.E. civil engineering: specific gravity of coarse aggregate for mix design, on portions reduced with the Sample Splitters (Riffle Boxes).
- Diploma civil engineering: aggregate testing, with samples brought to constant mass in the Drying Oven.
- Highway engineering: density of road aggregates.
- TVET materials-testing courses: practice in buoyancy weighing.
Standard Scope of Supply
Supply covers the 8000 g buoyancy balance, suspension hook, density basket of reinforced No. 8 wire mesh, galvanised water tank, 8 inch brass No. 4 sieve and one pan. A drying oven for bringing samples to constant mass is a separate item that can be quoted on request.
Packing, MOQ and Lead Time
Quotations are available for one set or for several benches, each giving the packing, delivery time and price for your quantity. The drying oven and sample splitter from this range can be quoted with it for colleges sourcing workshop tools for technical training institutes.
Science Lab Supplies holds an Importer-Exporter Code and, as a registered exporter, can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Lab managers can raise questions on the contact page, combine this set with other aggregate tests in the enquiry cart, or check the lab tender page for a tendered purchase.
Frequently Asked Questions
What size aggregate can be tested?
The buoyancy balance and basket are intended for coarse aggregate between 63 mm and 5 mm; the No. 4 sieve is used to remove finer material before the test.
What is the capacity of the balance?
The buoyancy balance has a capacity of 8000 g and runs on 220 V AC at 50 or 60 Hz. It works with the suspension hook and wire-mesh basket, so the same balance gives both the in-air and the underwater weighings.
How is the density found?
The sample is weighed in air and then in the basket suspended in the water tank. The difference gives its volume, from which density and specific gravity are calculated.
Who supplies this test set?
This buoyancy set is supplied by Science Lab Supplies from Ambala, India, and quotations are available to colleges and training institutes as well as to the tender contractors and distributors handling their purchases.
