The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

This may be assessed by tests of aggregate impact value (AIV) and aggregate crushing value (ACV). The common rock types range in AIV from good (basic volcanic, dolerite, quartzite. quartz gravels), through fair (granite, gravels composed of igneous or metamorphic fragments) to poor (weathered igneous rocks, clay-rich gravels).

Gabbro is also used to make a number of rough-cut products such as curbing, ashlars, paving stones, and other products. The most common use of gabbro is as a crushed stone or aggregate. Crushed gabbro is used as a base material in construction projects, as a crushed stone for road construction, as railroad ballast, and anywhere that a durable ...

Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.

CALCULATION: • Aggregate crushing value = B/A x • The result should be recorded to the first decimal place and the mean of the two results reported. • To achieve a high quality of pavement, aggregate possessing low crushing value should be preferred. 8.

The 100 kN crushing value of the coarse aggregate recycled using pulsed discharge was found to be greater than that of the original coarse aggregate. One explanation for this difference might be that the strength of the aggregate was decreased by the pulsed discharge, and the attached mortar pieces accelerated crushing.

The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.
