Flakiness Sieve Set
Flakiness Sieve Set (Product Code: SLE/CE/98) is a set of seven slotted steel sieves used to separate flaky particles, those thinner than 0.6 of their mean sieve size, from each size fraction of coarse aggregate in civil engineering and highway materials laboratories. Testing labs and engineering colleges use it for flakiness index testing across fractions from 6.3 to 63 mm, with slot sizes accurate to better than 0.1 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Flakiness Sieve Set Used For?
Road and concrete specifications cap the proportion of flat, flaky stones because they crush easily and pack poorly. With this set, the aggregate is first graded into its seven fractions between 6.3 mm and 63 mm; each fraction is then shaken on the slotted sieve made for it, and whatever passes through the slots is flaky. Adding the flaky mass from every fraction and dividing by the total gives the flakiness index.
Because a whole fraction is checked in one go, the set is faster than hand gauging for routine or large samples in commercial and college labs. Brush the slots clear after each use and store the sieves flat so the slot widths stay true. It is dependable engineering lab equipment for institutes preparing students for quality-control work on highways.
What to Specify When Ordering
- Number of complete 7-sieve sets required
- Whether you also need standard test sieves for the initial grading into fractions
- Whether a sieve shaker is wanted for the grading step
OEM Manufacturer
The Flakiness Sieve Set is produced by Jain Scientific Equipments Private Limited, known in the market as ScienceLab, which acts as the OEM. The slotted sieves are formed from heavy gauge steel sheet and finished at the company's own licensed factory at Saha, Ambala, Haryana, India.
Laboratories, colleges, dealers and importers order direct from the manufacturer, and can ask the factory itself about matching repeat sets. For company background, visit the ScienceLab profile.

Frequently Asked Questions
How many sieves are in the Flakiness Sieve Set?
The Flakiness Sieve Set consists of 7 sieves, one for each of the seven aggregate fractions between 6.3 mm and 63 mm. The aperture sizes listed for the set are 6.3, 10, 14, 20, 28, 37.5, 50 and 63 mm.
How accurate are the slots of the Flakiness Sieve Set?
The slot size of each sieve in the Flakiness Sieve Set is accurate to better than 0.1 mm. Accurate slots matter because the test separates particles thinner than 0.6 of their mean sieve size, so small errors would change the flakiness index.
What are the Flakiness Sieve Set sieves made of?
Each sieve in the Flakiness Sieve Set is made from heavy gauge steel sheet and coated with electrostatic paint. The painted finish protects the steel in regular laboratory use; clean and dry the sieves after testing wet or dusty aggregate.
Is the Flakiness Sieve Set used instead of a thickness gauge?
The Flakiness Sieve Set and a thickness gauge do the same job in different ways. The sieve set checks a whole size fraction at once, suiting larger routine samples, while a thickness gauge tests particles one by one, which suits teaching and small samples.
Who manufactures the Flakiness Sieve Set?
The Flakiness Sieve Set is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Buyers get quotations and repeat-order support directly from the manufacturer.
What should a quotation request for the Flakiness Sieve Set include?
A quotation request for the Flakiness Sieve Set should state the number of sets, whether grading sieves or a sieve shaker are also needed, and the delivery location. Send the details through our contact page or the enquiry cart.
