Material Testing Laboratory

The material testing laboratory deals with sampling of materials and carrying out quality tests on lateritic materials, aggregates, concrete mixes, steel, petroleum products and bituminous materials

2. Aggregates Sampling and Tests

Aggregates samples are taken either from the quarry at the point of crushing or from the stockpile

Los Angeles abration test

This test is to measure aggregate toughness and abrasion resistance such as crushing, degradation and disintegration using Los Angeles Abrasion Machine.

Aggregate crushing value (ACV)

It is a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

Flakiness index test

It is used to determine the particle shape of the aggregate specimen.
