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 – 12.5mm, 10mm and 2.36mm(PDF) RELATIONSHIP BETWEEN AGGREGATE CRUSHING VALUE,While aggregate crushing value of above 35 would be considered as weak aggregates. According to Uche and Muhammad (2011) , ACV of a concrete aggregate should not exceed 30%.Aggregate impact and crushing test - SlideShare,Feb 08, 2012· Two tests are required and the ten percent fines values (TFV) are averaged to obtain the final result, reported to the nearest 10 kN (for forces > 100kN)PROCEDURE - Aggregate Crushing Value (SS 1974)1. The apparatus and sample preparation is identical with that described above for the Ten Percent Fines Test.2.
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.Aggregate Testing Lab Equipment – Sun LabTek,Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load.Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates,Standard of Crushing Value of Coarse Aggregates for,,Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.
