Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.Aggregate Crushing Value Test – Determine Aggregate,,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 Value Test - Significance & Test,,Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report
“Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined and used instead.Aggregate Crushing Value - Civil Engineering,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 ValueAggregate Crushing Value Test - Procedure And Result,“Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined and used instead.
What is Aggregate Crushing Value? 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.DETERMINATION OF AGGREGATE CRUSHING VALUE,The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUSAggregate crushing value test | Step by Step Procedure,,It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface. This test must be done before it comes to road and pavement construction. Calculation Table for aggregate crushing value
The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like(PDF) Aggregate Crushing Value Test | busva gopal,,Aggregate Crushing Value Test.

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 Test - Vidyarthiplus,aggregate crushing value indicates strong aggregates, as the crushed fraction is low. ~hus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.CORRELATION BETWEEN AGGREGATE CRUSHING VALUE OF,Aggregate Crushing Value (ACV) is an index of loss of coarse aggregate (CA) under sustained loading. However, ACV is not considered in concrete mix design according to ACI 211.1(ACI 211.1, 2009). In this paper effect of ACV of CA on compressive strength of concrete has been explored. Coarse,

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 i.e. low crushing value should be preferred. Lower crushing,,
