Apr 24 2019 Aggregate Crushing Value Test IS Code IS Code for this test is IS 2386 part 3 Aggregate Crushing Value Test Apparatus and Tools One metal cylinder for test and open on both ends dia 152 mm height 130 mm to 140 mm Plunger dia 150 mm Base plate thickness 63 mm square of 200 mm to 230 mm
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 standardized conditions and the strength of the aggregate used in road
Aggregate Crushing Value This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963 i The aggregates passing through 125mm and retained on 10mm IS Sieve are ovendried at a temperature of 100 to 110oC for 3 to 4hrs
Aggregates Crushing Value test according to BS 812110 According to the standard the compression machine control system shall automatically compensate these instabilities and complete the test in an overall time of 10 min 30 s Dividing the whole test duration of 600 seconds into 10 intervals of 60 seconds each each 40 kN load step should be reached in 60 3 seconds
One of the test in which concrete material can fail is due to crushing under compressive stress Aggregate crushing test is standardized by IS 2386 partIV and used to verify the crushing strength of aggregates The aggregates should be oven dried which can
Crushing Test on Aggregates The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load If the aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate
Procedure for crushing strength of aggregate Before testing the aggregate should be in surface dry can achieve The aggregates passing through 125mm and retained on 10mm IS sieves are selected After sieving aggregates a cylindrical measure is taken and find the empty
The Aggregate Crushing Value ACV Test Set measures how resistant an aggregate is when being crushed under a gradually applied compressive load Each set consists of steel cylinder plunger base plate cylindrical measure and tamping rod
Objective 1 Determine the aggregate crushing value of coarse aggregate 2 Assess suitability of coarse aggregates for use in different types of road Theory The aggregate crushing value give a relative measure of the resistance of

Mar 31 2017 AGGREGATE CRUSHING TEST The strength of coarse aggregate is assessed by aggregate crushing test the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load Lower the aggregate crushing value greater will be the resistance to crushing under gradually applied compressive load
Jul 16 2014 It has been found that for majority of aggregates the aggregate crushing value and aggregate impact values are numerically similar within close limits For deciding the suitability of soft aggregates in base course construction aggregate impact test is commonly used
Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing degradation and disintegration This test is carried out by AASHTO T 96 or ASTM C 131 Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine
The test aims at looking for the forces required to produce 10 of fine values ie weight of fines aggregatesweight 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
