BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load The method is applicable to aggregates passing a 14 0 mm test sieve and retained on a 10 0 mm test sieve
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 Crushing Value (ACV) can be determined by using a simple formula This test is repeated once or twice and the average crushing value of the aggregate is determined The average crushing value in the different tests is the actual crushing value of aggregate Important points to re 1It is recommended that the crushing value of

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 than 30 then 10 finer aggregate is suggested to use The aggregate whose crushing value is less than 30 can be used for

AGGREGATE CRUSHING VALUE (IS 2386 Part 4 1963) Note down the observations in the proforma then compute the aggregate crushing value The mean of two observations rounded to nearest whole number is reported as the “Aggregate crushing Value” Test with Non standard Sizes of Aggregates
Feb 03 2012 From the experiment we get average percent wear are 22 34 still not exceeding JKR’s standard 30 So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load
2020 04 03 AGGREGATE CRUSHING VALUE (IS 2386Part 41963) May 08 2013 Aggregate crushing Value =(W B W A) 100 Record The mean of the two results is reported to the nearest whole number as the aggregate
Oct 16 2017 Significance The aggregate crushing value gives relative measure of the resistance to crush under a gradually applied compressive load Definition It is defined as the ratio of the weight of fines to the total sample weight expressed as a percent when tested as per the IS procedure
Oct 04 2020 The aggregate crushing value is an indirect measure of crushing strength of the aggregates Low aggregate crushing value indicates strong aggregates as the crushed fraction is low Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components
Aggregate Crushing Value Test Apparatus ( Superb Technologies ) is used for measuring resistance of an aggregate to crushing Aggregate rushing value apparatus consist of plunger and base plate having 6mm thick base and 140mm high with base Specifications steel Cylinder 120 mm internal dia x 150 to 120 mm height
Aggregate crushing value test Step by Step Procedure Aug 11 2020 Aggregate Crushing Value (ACV) can be determined by using a simple formula This test is repeated once or twice and the average crushing value of the aggregate is determined The average crushing value in the different tests is the actual crushing value of

The aggregate crushing value is defin ed as a ratio of the weight of fines passing the specified sieve (236 mm) to the total weight of the sample expressed as a percentage Aggregate crushing value 35 weak for pavement Aggregate crushing value 10 exceptionally strong Rock group Crushing value
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 pressive load of 400 kN 2 APPARATUS 21 An
Apr 26 2018 Calculation of aggregate crushing value The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2 36mm sieve) to the total weight of sample expressed in percentage W1= Weigh of the total aggregates (Wa We) W2= Weigh of aggregates passing through 2 36mm IS sieve
With aggregate of aggregate impact value higher than 30 the result may be anomalous Also aggregate sizes ‘larger than 14 mm are not appropriate to the aggregate impact test The standard aggregate impact test shall be made on aggregate passing a 14 0 mm BS test sieve and retained on a10 0 mm BS test sieve
