Aggregate Crushing Value Test Procedure, Result
The aggregate Crushing Value Test is an important test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm in diameter and 25 This document gives the determination of aggregate crushing value ( ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the ISO 20290-3:2019(en), Aggregates for concrete ? Test methods for

It is generally a dry operation and is usually performed in two or three stages.i.e primary,secondary and tertiary stage. In Primary crushing the feed size of ore can be as large as 1.5m and is reduced to 10-20cm in Crushing PPT SlideShare

Hardness of aggregates Hardness of aggregates is the ability of the aggregate to withstand wear or load or applied pressure. This hardness is depending on the type of parent rock The test that can obtain the hardness is the abrassion test. A satisfactory aggregate should have an abrassion value of not more than 30% for Due to expansion in infrastructure and increased development of urbanization in Ethiopia, most of the places are covered either by impermeable cement concrete or bitumen that blocks the percolation of water from rainfall.

8.3.1 Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.NOTE A single test specimen is that quantity of material required to fill the cylinder (see 8.1 and Table 2).

The aggregate size fraction taken for this test can also be as per the relevant national standards. NOTE Minor variations in grading divisions can be allowed in respective national standards. The method is not suitable for testing aggregates with an aggregate crushing value higher than 30.If the aggregates are weak, the stability of the concrete structure is adversely affected. The strength of coarse aggregates is assessed by Aggregate Impact Value test. The aggregate impact value provides a relative measure of resistance to sudden shock or impact. APPARATUS 1.
