Get PriceDoc Aggregate Crushing Value Test Lab Report Adnan, 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 Aggregate Crushing Value Coarse Aggregate
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load to achieve a high quality of pavement aggregates possessing low aggregate crushing value should be preferred
Then crushed aggregates are then sieved through 236 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value a value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates
Aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is 2386 part iv 1963 the apparatus used is cylindrical measure and plunger compression testing machine is sieves of sizes 125mm 10mm and 236mm
The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate the aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load for achieving a high quality of pavement aggregate of higher crushing strength ie low
The aggregate crushing value acv provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load two versions available 150 standard and 75 mm dia the apparatus comprehend cylinder plunger base plate tamping rod and measure
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
Aggregate crushing value of coarse aggregate note 1 the aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load with aggre gate of aggregate crushing value 30 or higher the result may be anomalous and in
May 08 2013 objective for determination of the aggregate crushing value of coarse aggregate which passes 125 mm is sieve and retained on 10 mm is sieve reference standard is 2386 part iv1963 methods of test for aggregate for concrete part iv mechanical properties equipment apparatus steel cylinder sieves 125mm10mm cylindrical metal measure tamping rod balance 0
An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger the specimen is then loaded via the plunger the load crushes the aggregate to an extent depending on the crushing resistance of the material it is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value acv
Aggregate crushing value test determine aggregate aggregate crushing value test determine aggregateaggregate 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 construction is expressed by numerical index
Aggregate crushing value test procedure and limits august 11 2019 apr 24 2019 if the aggregate are weak in resistance the stability of the pavement or structure is likely to be adversely affected so that the crushing value of coarse aggregate is required 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
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
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 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kn 2 apparatus 21 an
