The aggregate impact value (AIV) test shows how an aggregate behaves under the repeated shocks that traffic and compaction apply to road layers. A sized sample is measured out in the 75 mm × 50 mm metal measure, compacted with the 10 mm tamping rod and set in position on the base. The hammer is lifted to the set height and dropped the number of times the method specifies, with the blow counter keeping the tally.
The crushed sample is then sieved, and the fines produced are expressed as a percentage of the original mass; a lower figure means a tougher aggregate. Colleges often run this test alongside the crushing value test so students can compare static and dynamic strength. This robust frame is typical of the engineering lab equipment in India used by polytechnics and TVET centres; always engage the hammer lock while placing or removing the sample.
The Aggregate Impact Tester is built by Jain Scientific Equipments Private Limited, which trades as ScienceLab, acting as the original equipment manufacturer. Its base, guides, hammer and counter mounting are produced and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India.
Engineering institutions, testing laboratories, dealers and importers buy direct from the maker, so questions on spares or repeat orders go straight to the people who build it. Read about the company on the ScienceLab company profile.

The Los Angeles abrasion test indicates whether a road stone or concrete aggregate is hard enough to resist the grinding and knocking it will meet in service. A graded sample is loaded into the drum together with the abrasive charge the test method specifies, the counter is set, and the drum turns at 31–33 rpm until the machine stops on its own at the preset count. The sample is then sieved and the loss is reported as a percentage of the original mass.
Automatic stopping removes counting errors and frees the operator during long runs, which is valuable in teaching labs where several groups share one machine. Use the interlock to hold the drum steady while loading and emptying it. For institutes building a highway materials lab, this is core engineering lab equipment in India alongside impact and crushing value tests.
ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), the OEM behind this machine. The rolled steel drum, frame and control mounting are produced at the company's licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414).

The Dorry test grades the hardness of rock and stone by how quickly it wears when rubbed against a turning disc under a steady stream of sand. Each specimen sits in its weighted container so that it bears on the disc with a constant pressure, the hoppers are opened to feed sand, and the disc turns at 28–30 RPM for the number of revolutions the test calls for. Loss of mass or thickness after the run shows how the stone would resist foot traffic, wheels or flowing water.
Weigh specimens carefully before and after the test, keep the sand dry so it flows evenly from the hoppers, and empty the tray outlet between runs. This machine suits geology and highway-materials teaching in engineering colleges, as well as quality checks on paving and flooring stone at technical institutes.
Jain Scientific Equipments Private Limited, trading as ScienceLab, makes the Dorry Abrasion Testing Machine as its own OEM product. The disc drive, circular tray, hopper bracket and weighted containers are manufactured and assembled at the company's licensed factory at Saha, Ambala, Haryana, India.
Because buyers deal with the maker rather than a reseller, engineering colleges, laboratories, dealers and importers can take up repeat orders and questions about wear parts directly with the factory. Learn about the company on the ScienceLab profile page.

Thickness gauge (Product Code: SLE/CE/97) is a slotted gauge used to decide whether individual aggregate particles are flaky, meaning thinner than 0.6 of their nominal size, in civil engineering and highway materials laboratories. Materials labs and engineering colleges use it for flakiness index work; it has seven slots from 4.9 × 30 mm to 33.9 × 100 mm on a 310 × 130 × 10 mm body. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
| Parameter | Detail |
|---|---|
| Purpose | Identifies flaky aggregate particles (thickness less than 0.6 of nominal size) |
| Number of slots | 7 |
| Slot sizes | 4.9 × 30 mm, 7.2 × 40 mm, 10.2 × 50 mm, 14.4 × 60 mm, 19.7 × 80 mm, 26.3 × 90 mm and 33.9 × 100 mm |
| Dimensions | 310 × 130 × 10 mm |
| Weight | 0.4 kg (approx.) |
| Product code | SLE/CE/97 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
Flaky particles break easily under rollers and traffic and reduce the workability of concrete, so specifications limit how many a coarse aggregate may contain. For the flakiness index, the sample is first sieved into size fractions, and each particle of a fraction is tried by hand in the slot that matches that fraction. Particles that pass through the slot are flaky; their total mass as a percentage of the sample mass gives the flakiness index.
The gauge is light and small enough to use at a bench or on site, and one gauge covers all seven fractions. Keep the slot edges clean and free of burrs, and test one fraction at a time to avoid mixing results. It is a practical piece of lab equipment for technical institutes teaching highway materials and concrete technology.
This Thickness gauge is an OEM item from Jain Scientific Equipments Private Limited, which operates under the ScienceLab name. It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct rather than through a trading intermediary.
Colleges, testing laboratories, dealers and importers can place repeat orders with the manufacturer itself, which is useful when several benches need matching gauges. Read more on the ScienceLab company profile.
Aggregate shape testing usually needs these items too:
See the complete range of Civil Engineering Lab Equipment.
What slot sizes does the Thickness gauge have?
The Thickness gauge has seven slots: 4.9 × 30 mm, 7.2 × 40 mm, 10.2 × 50 mm, 14.4 × 60 mm, 19.7 × 80 mm, 26.3 × 90 mm and 33.9 × 100 mm. Each slot is used for one size fraction of the aggregate sample.
When is an aggregate particle flaky according to the Thickness gauge?
With the Thickness gauge, a particle is treated as flaky when its thickness is less than 0.6 of its nominal size, which shows up when it passes through the slot for its fraction. The mass of flaky particles gives the flakiness index.
How big and heavy is the Thickness gauge?
The Thickness gauge measures 310 × 130 × 10 mm and weighs about 0.4 kg. Its compact size makes it easy to use at a laboratory bench or to carry to a quarry or site for quick checks.
What is the difference between the Thickness gauge and a flakiness sieve set?
The Thickness gauge is used to test particles individually by hand in its seven slots, which suits teaching and small samples. A flakiness sieve set uses slotted sieves to check a whole fraction at once, which is quicker for larger routine samples.
Who manufactures the Thickness gauge?
The Thickness gauge is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Quotations and repeat orders are handled directly by the manufacturer.

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.
| Parameter | Detail |
|---|---|
| Number of sieves | 7 |
| Flakiness criterion | Particle thickness less than 0.6 of its mean sieve size |
| Size fractions covered | Seven fractions from 6.3 mm to 63 mm, each examined separately |
| Aperture sizes listed | 6.3, 10, 14, 20, 28, 37.5, 50 and 63 mm |
| Slot accuracy | Better than 0.1 mm |
| Construction | Heavy gauge steel sheet |
| Finish | Electrostatic paint coating |
| Product code | SLE/CE/98 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
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.
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.
These items complete a flakiness and grading workstation:
Browse all Civil Engineering Lab Equipment.
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.

Cylindrical Measures (Product Code: SLE/CE/99) are calibrated sheet-iron containers of known volume used to determine the bulk density, or unit weight, of fine and coarse aggregates in civil engineering and concrete technology laboratories. Engineering colleges, ready-mix and site labs pick a size to suit the aggregate, choosing from capacities of 3, 5, 7, 10, 15, 20 and 30 litres, each with carrying handles. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
| Parameter | Detail |
|---|---|
| Purpose | Determination of bulk density (unit weight) of aggregates |
| Construction | Calibrated cylindrical measures of sheet iron with handles |
| Capacities available | 3, 5, 7, 10, 15, 20 and 30 litres |
| Supplied with | One tamping rod, 16 mm diameter × 600 mm long |
| Product code | SLE/CE/99 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
Bulk density tells a mix designer how much aggregate by mass fills a given volume, which is needed to convert between mass and volume batching and to estimate the voids that cement paste must fill. The empty measure is weighed, filled with aggregate either loosely or in layers compacted with the 16 mm tamping rod, struck off level with the rim, and weighed again. Dividing the aggregate mass by the known capacity gives the bulk density.
Larger measures are chosen for coarser aggregate so that the sample represents the material fairly, which is why the range runs from 3 up to 30 litres. Keep the measures dry and dent-free, since damage changes their volume. A full set is practical equipment for laboratories in technical institutes that teach concrete mix design.
Cylindrical Measures in this range are manufactured by Jain Scientific Equipments Private Limited under its ScienceLab brand, as the OEM. The sheet-iron measures and their handles are fabricated at the company's own licensed factory at Saha, Ambala, Haryana, India.
ScienceLab is registered as an MSME manufacturer (Udyam UDYAM-HR-01-0003714), and export shipments are handled under Importer-Exporter Code AAECJ8618A (DGFT). Buyers therefore deal with the maker for quotations and repeat orders; see the ScienceLab company profile for more.
Items typically used with these measures in aggregate testing:
View the complete Civil Engineering Lab Equipment range.
What capacities do the Cylindrical Measures come in?
The Cylindrical Measures are available in capacities of 3, 5, 7, 10, 15, 20 and 30 litres. Smaller measures suit fine aggregate and small samples, while the larger sizes are chosen for coarse aggregate so that the test sample is representative.
What are the Cylindrical Measures made of?
The Cylindrical Measures are calibrated measures made of sheet iron and fitted with handles for lifting when full. Keep them clean, dry and free from dents, because any change in shape alters the internal volume used in the bulk density calculation.
Is a tamping rod included with the Cylindrical Measures?
Yes. The Cylindrical Measures are supplied complete with one tamping rod, 16 mm in diameter and 600 mm long, for compacting the aggregate in layers during the rodded bulk density test. Extra rods can be added to the same quotation.

Density Basket (Product Code: SLE/CE/100) is a wire-mesh basket used to hold coarse aggregate while it is weighed under water for specific gravity, density and water absorption tests in civil engineering laboratories. Materials labs and engineering colleges hang it from a buoyancy balance; it is built in brass or GI with 6.3 mm or 4.75 mm stainless steel wire mesh, about 203 mm across and high. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
| Parameter | Detail |
|---|---|
| Frame material | Brass or GI, ruggedly constructed |
| Mesh | Stainless steel wire mesh, 6.3 mm or 4.75 mm size |
| Construction | Reinforced No. 8 wire mesh |
| Size | Approx. 20 cm diameter × 20 cm high (8 in × 8 in, 203 × 203 mm) |
| Handle | Bail-type handle |
| Net weight | 2 lb (0.91 kg) |
| Product code | SLE/CE/100 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |

To find the specific gravity and water absorption of coarse aggregate, a soaked sample is placed in the basket, lowered into water and weighed while fully immersed. The same sample is then surface-dried and weighed in air, and finally oven-dried and weighed again. From these three weights the laboratory calculates particle density, specific gravity and the percentage of water the aggregate absorbs, all of which feed into concrete mix design.
The bail-type handle lets the basket hang freely from the balance hook so it does not touch the sides of the water tank. Choose the 4.75 mm mesh when finer coarse particles must be retained, shake off trapped air before weighing, and rinse the basket after use. It suits engineering lab equipment set-ups in colleges and polytechnics that teach aggregate testing.
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM for this Density Basket. The frame, mesh and handle are assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and sold factory-direct.
Laboratories, institutions, dealers and importers can order mixed materials and mesh sizes from the maker in one quotation and come back to the same manufacturer for repeat baskets. Company background is on the ScienceLab profile.
The basket works as part of this specific gravity set-up:
See all Civil Engineering Lab Equipment.

Buoyancy Balance Apparatus (Product Code: SLE/CE/101) is a weighing system that measures a specimen in air and then suspended in water, used to find the specific gravity, density and water absorption of aggregates, concrete and rock in civil engineering laboratories. Materials-testing labs and engineering colleges choose it for its 6000 g capacity with 0.1 g readability and a mechanical lift that raises the water tank to the specimen. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
| Parameter | Detail |
|---|---|
| Balance capacity × readability | 6000 g × 0.1 g |
| Frame | Rigid support frame incorporating a water tank mounted on a platform |
| Immersion method | Mechanical lifting device raises the water tank through the frame height to immerse the specimen suspended below the balance |
| Dual use | Balance can also be used as a standard weighing device |
| Supplied with | Frame, water tank and suspension hook |
| Power supply | 220–240 V AC, 50–60 Hz, 80 W |
| Product code | SLE/CE/101 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
The apparatus applies Archimedes' principle: a specimen weighs less in water by exactly the weight of water it displaces, so weighing it in air and immersed gives its volume and hence its density. The specimen, or a wire basket of soaked aggregate, hangs from the suspension hook beneath the balance. After the reading in air, the lifting device raises the tank until the specimen is fully submerged, and the immersed reading is taken without disturbing the hook.
Raising the water rather than lowering the sample keeps the load steady and the readings repeatable, which matters with 0.1 g resolution. When density work is finished, the balance serves as an everyday weighing device, so one bench unit covers both jobs. This makes it versatile laboratory equipment for technical institutes running aggregate, concrete and rock tests.
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM for the Buoyancy Balance Apparatus. The system is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied direct from there.
Engineering colleges, testing laboratories, dealers and importers receive quotations from the manufacturer itself and can raise questions on spares or additional systems with the same team. Read about the company on the ScienceLab company profile.
