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.The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.

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.2.1.2 Crushed Stone Sand - Fine aggregate produced by crushing hard stone. 2.1.3 Crushed Grace1 Sand - line aggregate produced by crushing natural gravel. . 2.2 Coarse Aggregate -- Aggregate most of which is retained on 4 75-mm IS Sieve and containing only so much finer material as is permitted for.
Mar 28, 2021 Aggregate Crushing test (IS 2386(Part 4) 1963 BS 812–110 1990) Aggregate crushing test values indicates the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads.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 Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm [ ].

Aggregate Crushing Test Full Reading. 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 construction is expressed by numerical index aggregate crushing.Reading of the load in KN is noted from dial gauge. The y axis represents the Impact value of the aggregate when the certain percentage of recycled aggregate is used as shown in X axis. Fig 3 Crushing value The crushing value graph represents the variation of crushing value when the amount or the percentage composition of the recycled.
