To Determine Aggregate Impact value of Aggregate

Aggregate is a granular material obtained by processing natural materials.BS882 splits aggregate into coarse and fine elements, coarse being described as gravel or crushed rock and fine being described as sand.Aggregate consists of particles of a rock, of a controlled particle size distribution, used in the construction of a building or civil engineering structure.

Polished Stone Value Test Procedures and Equipment

Aggregate Impact Test This test is specified in BS812:Part 3 : 1975. Resistance to impact of a sample of aggregate is measured by subjecting a 28mm deep bed of 14 mm to 10 mm chippings, in a 102mm diameter hardened steel cup, to 15 blows from a 14 kg hammer falling from a height of 380mm.

7 Lab Test on Aggregate Should Satisfy for Use in Concrete

In order to evaluate the resistance to impact of aggregate, the aggregate impact test is conducted. Aggregate impact value gives the idea about how much impact load can be resisted by aggregate. Actually, aggregate should be sufficiently tough to resist their disintegration due to impact. This distinctive property is measured by impact value test.

What is the significance of ten percent fines value in

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
