(DOC) Aggregate crushing value Test Lab Report | Adnan,
The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like runways and roadways. Discussion…Aggregate Impact Value Test, Procedure, Result & Standards,May 21, 2020· Preparation of Aggregate Impact Value Test:-The aggregate which uses for the sample is passed through the 12.5mm IS sieve and retain on the 10mm IS sieve. The aggregate which is retained on the 10mm sieve is dried in an oven for a time period of 4aggregate crushing value test report discussion,· Aggregate impact and crushing test . is recorded to the nearestwhole number as the Aggregate Impact Value.The AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose. . e.g.,Australia and New Zealand, only use the latter test.DISCUSSION(a) Report the geological description of the aggregate .Abrasion Test On Aggregate (Los Angeles Abrasion Test),Jan 06, 2019· 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 Small-Size Coarse Aggregate by Abrasion and Impact inAggregate Crushing Value Test - Significance & Test,,Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.DCC3113 DETERMINATION OF AGGREGATE IMPACT VALUE.,Dec 15, 2017· Classification of aggregates using Aggregate Impact Value is as given below: Aggregate Impact Value Classification <20%.= Exceptionally Strong 10 – 20% .=Strong 20-30%. =Satisfactory for road surfacing >35%.= Weak for road surfacing 5. 5 APPARATUS 1. Aggregate Impact Value Test Machine 2. BS test sieve 3. A metal tamping rod 4.
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.aggregate impact value test conclusion – we civil engineers,AIM: To determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) - 1963. APPARATUS: i) Cylindrical measure and plunger ii) Compression testing machine iii)discussion of aggregate crushing value | Prominer,,Download PDF - Bentham Open. Dec 13, 2017 Test results showed that aggregates produced are of lesser specific gravity, Aggregate crushing value apparatus AIM- 455 confirming the requirement 13 is used for conducting this RESULTS AND DISCUSSIONS.conclusion of aggregate impact test | Mining & Quarry Plant,Aug 29, 2013· AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse and 230mm length, rounded at one end and Oven. conclusion of aggregate impact test – South africa ore,,
