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 ( 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.

Abrasion Test On Aggregate (Los Angeles Abrasion Test)
Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in Los Angeles Machine.

Aggregate Crushing Value Test – Determine Aggregate ...
Concept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under ...

average crushing value of aggregate
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS An ...

Aggregate Crushing Value Test Significance Test ...
Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load.

Aggregate crushing value test | Step by Step Procedure ...
The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for ...

7 Lab Test on Aggregate Should Satisfy for Use in Concrete
If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR USE IN .
Sep 12, 2015· Crushing Test Fig1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS: 2386 partIV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied ...
