Get PriceSplitting tensile strength for rock core; TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing.
Get PriceAggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
Get PriceOct 01, 2013 The total percent mass loss is represented as the aggregate crushing value (ACV). The natural aggregate had the lowest ACV indicating the highest crushing strength, followed by the RCA-1, RCA-2 and RCA-3. Both the Micro-Deval abrasion resistance and the ACV are in close agreement. 3.2.1. Aggregate crushing value and response of confined coarse ...

Get PriceAggregate 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.
Get PriceHowever, low strength aggregates having lesser crushing strength are used in base and sub-base courses of pavements. IRC have specified aggregates crushing values of the coarse aggregates used for cement concrete surface should not exceed 30%.
