AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.

Aggregate Ten Percent Fine Value TPFV The other way of representing the strength of aggregate is the ten percent fine value TPFV, that is basically the load needed for 10 fines. As compared to aggregate crushing value test this test is more reliable for representing the strength of aggregate.

May 17, 2019 Procedure The aggregate sample The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.

Mar 20, 2021 For this reason, a simple test known as 10 per cent fines value is introduced. When the aggregate crushing value become 30 or higher, the result is likely to be inaccurate, in which case the aggregate should be subjected to 10 per cent fines value test which gives a better picture about the strength of such aggregates.

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.

General description Aggregate crushing Value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Ten Percent Fines Value used for testing aggregate smaller than 10 mm.

Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. Fine aggregates are defined as those passing 2.36mm sieve. The test aims at looking for the forces required to produce 10 of fine values i.e. weight of fines aggregatesweight of all aggregates 10.
