In road construction, the quality of aggregates is assessed by the crushing strength of aggregatFor higher quality of roads, the aggregate should possess low aggregate crushing value Here I am going to teach you how to determine the crushing strength of aggregatFirst, let us check what are the various apparatus needed for this experiment
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
Enhancement of Pilot and Automax compression machines for ACV test Aggregates Crushing Value test according to BS 812:110 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 strength and durability of crushed rock aggregates depends on the , indicates that the aggregate possess mean aggregate crushing value (ACV) , Relationship between aggregate crushing value and water absorption and bulk density
Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions Aggregate crushing value is a numerical index of the strength of the aggregate and it ,
The strength of coarse aggregates is assessed by aggregates crushing test 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, aggregate possessing low aggregate crushing value should be preferred

coarse aggregates, the variation of aggregate crushing value of different coarse aggregates, strength gain of concrete with time for different coarse aggregates and to establish a relation between aggregate crushing value of coarse aggregate and compressive strength of concrete In the study, Portland Composite Cement (PCC) has not been used
Compressive strength of concrete cube test provides an idea about all the characteristics of concreteBy this single test one judge that whether Concreting has been done properly or not Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structur
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
