Chat Online### Resistance to fragmentation of recycled concrete

· This work deals with the characterization of fragmentation of recycled concrete aggregate (RCA) by the Los Angeles test. The standard testing procedure for the Los Angeles index requires the measurement of the mass passing 1.6 mm after 500 revolutions of the drum. Questions arise on the significance of this measure for RCA as the resistances of the mortar of the original aggregate and of

contrary the aggregate crushing test is simple rapid and gives fairly consistent results. Applications of Aggregate Crushing Test ItThe 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. hus the test can be

Chat Online### Properties of AggregatesCivil Snapshot

· The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Impact Value. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact. The impact value of an aggregate is sometime used as an alternative to its crushing value.

· The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (Figure 22 1). Dry aggregates passing through 12.5 mm sieves and retained 10 mm sieves are

Chat Online### Aggregate crushing testStrength of aggregate

· 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. Higher crushing strength means lower crushing value

Chat Online### Aggregate 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.
