Aggregate Crushing Value Apparatus
Product Code : EL-ATLE-10465
Aggregate Crushing Value Apparatus (code EL-ATLE-10465) is a test set that gives a relative measure of how well an aggregate resists crushing under a gradually applied compressive load. It comprises a 150 mm ± 0.5 mm diameter steel cylinder, a 148 mm ± 0.5 mm plunger, a 200 to 230 mm square base plate, a 115 mm diameter metal measure and a 16 mm × 600 mm tamping rod, all in powder coated or galvanized steel.

What Is the Aggregate Crushing Value Apparatus Used For?
The aggregate crushing value shows how readily an aggregate breaks down under a slowly increasing compressive load, which matters for stone used in road bases, surfacings and concrete. The operator fills the metal measure with the test fraction in layers, tamping each with the rod, transfers the material to the cylinder standing on its base plate and seats the plunger on top; the load is then applied through the plunger by a compression testing machine. The crushed material is sieved, and the mass of fines produced, as a percentage of the original sample mass, is the crushing value, a lower value indicating a stronger aggregate.
What to Specify When Ordering
- Quantity — the number of crushing value sets required.
Frequently Asked Questions
What does the Aggregate Crushing Value Apparatus measure?
It gives a relative measure of the resistance of an aggregate to crushing when a compressive load is applied gradually, expressed as the crushing value of the sample.
Which parts make up the set?
Each set consists of a steel cylinder, a plunger, a base plate, a cylindrical metal measure and a tamping rod, all made of powder coated or galvanized steel.
What are the cylinder and plunger dimensions?
The cylinder is 150 mm ± 0.5 mm in diameter and 130 mm to 140 mm high, and the plunger is 148 mm ± 0.5 mm in diameter and 100 to 115 mm high.
What size are the base plate, measure and tamping rod?
The base plate is 200 to 230 mm square and 6 mm thick, the metal measure is 115 ± 0.5 mm in diameter by 180 ± 0.5 mm high, and the tamping rod is 16 mm by 600 mm with rounded ends.
How is the crushing value worked out?
After loading, the crushed sample is sieved and the mass of fines that pass is expressed as a percentage of the original mass; a lower figure shows greater resistance to crushing.
Which standards are listed for this apparatus?
The standards listed for the Aggregate Crushing Value Apparatus are IS 2376 (Part IV) and BS 812:111.
