Aggregate Crushing Value Apparatus. Manufacturer,Supplier and Exporter in India

Aggregate Crushing Value Apparatus (Product Code: SLE/AG/01) is a steel cylinder-and-plunger test set used to measure the relative resistance of coarse aggregate to crushing under a gradually applied compressive load in civil engineering laboratories. Polytechnics and highway labs use this engineering lab equipment to compare stone sources; its 150 mm cylinder takes a 148 mm plunger, with base plate, metal measure and tamping rod included. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Aggregate Crushing Value Apparatus Used For?

The metal measure is filled with prepared aggregate to fix the quantity used for each test. That aggregate is placed in the cylinder in layers, each compacted with the tamping rod, and the plunger is seated level on the surface. The assembly on its base plate goes into a compression testing machine and the load is applied steadily as your test method sets out. After unloading, the crushed material is sieved and the fines are weighed; fines as a percentage of the original sample mass give the crushing value, so a lower figure means a tougher aggregate.

Because the set is simple and robust, it is common lab equipment for technical institutes where students run the test in groups. Use the same measure and tamping routine for every sample so results can be compared, keep the cylinder bore and plunger face free of grit so the plunger does not bind, and wipe all parts dry after cleaning.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this crushing value set. The apparatus is made at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, and it is supplied factory-direct to colleges, testing laboratories, dealers and importers. If you later need a replacement plunger or tamping rod, ask us and the request goes straight to the maker. Read more on the ScienceLab company profile.

Related Civil Engineering Lab Equipment

A crushing value test depends on a representative dry sample, a loading machine and careful sieving. These items fit the same workflow:

• Automatic digital compression testing machine — a compression machine of the kind used to apply the gradually increasing load to the cylinder and plunger.
• Aggregate Impact Tester — a companion toughness test in which a falling hammer strikes the aggregate instead of a slow load.
• Riffle Sample Divider — reduces a large field sample to a representative portion before it goes into the measure.
• Test Sieves — for separating the fines produced by crushing so they can be weighed.
• Oven, 43 litre — dries the aggregate before testing so moisture does not distort the result.

Frequently Asked Questions

What is included with the Aggregate Crushing Value Apparatus?
The Aggregate Crushing Value Apparatus consists of a steel cylinder, a plunger, a base plate, one cylindrical metal measure of 115 ± 0.5 mm dia x 180 ± 0.5 mm high, and a tamping rod 16 mm in diameter and 600 mm long with both ends rounded.

Is a compression testing machine supplied with the Aggregate Crushing Value Apparatus?
No. The Aggregate Crushing Value Apparatus is the cylinder, plunger and accessories only; the load is applied with a separate compression testing machine. If you need help matching the set to the machine in your laboratory, contact us before ordering.

How do the cylinder and plunger of the Aggregate Crushing Value Apparatus fit together?
The cylinder of the Aggregate Crushing Value Apparatus is 150 mm ± 0.5 mm in diameter and the plunger is 148 mm ± 0.5 mm, so the plunger slides inside the cylinder and bears evenly on the compacted aggregate during loading.

How should the Aggregate Crushing Value Apparatus be looked after?
Brush all fines out of the Aggregate Crushing Value Apparatus after each test, wash off any mud, dry every part fully and store the plunger beside the cylinder so that its face and the cylinder bore are not knocked or scratched.

Who manufactures the Aggregate Crushing Value Apparatus?
The Aggregate Crushing Value Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations, repeat orders and replacement-part requests are handled directly by the manufacturer.

Can a calibration or inspection certificate be provided with the Aggregate Crushing Value Apparatus?
Please discuss documentation for the Aggregate Crushing Value Apparatus with us through our contact page before ordering. We will confirm what can be supplied with your specific order rather than promise a document in advance.

What should a quotation request for the Aggregate Crushing Value Apparatus include?
Give the product code SLE/AG/01, the number of sets, the delivery address in India or abroad and any tender specification the Aggregate Crushing Value Apparatus must match, so the dimensions can be checked against your requirement.
