Thus, the water absorption rate and crushing value can approximately reflect the property differences of RA. (4) Euclidean distance calculations show that there is a certain correlation among apparent density, water absorption rate, and crushing value. The lower the apparent density, the larger the water absorption rate and crushing value.
Click on the cylinder to transfer the aggregate into 2.36mm sieve. Once the aggregate is added into sieves click on the set of sieves to place it in the mechanial shaker. Calculate the weight of aggregate retained on pan, click on NEXT button to proceed. Calculate the average aggregate crushing value, click on CHECK button to evaluate the answer.

Aug 15, 2018 When crushed concrete is charged by the ton, the price can vary anywhere from $6 to $14 per ton. By the yard, crushed concrete can cost anywhere from $20 to $30. Generally, the more you purchase, the lower that price will be per yard or ton. Mainslandscapesupply.com, for example, sells its crushed concrete from $22.95 to $24.95.
Overview Pike’s construction aggregates are locally mined materials used in construction, including stone dust, sand, gravel, crushed stone, and recycled concrete.

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.
Soft aggregates will be quickly crushed into powder, while hard aggregates are quite resistant to crushing. The test will also determine the quality of the aggregate. The L.A. abrasion test is widely used as an indicator of the quality or relative competence of mineral aggregates.
Oct 01, 2016 Also read: Determination of Light Weight Pieces in Aggregates. 12. Crushing Value. The aggregates crushing value gives a relative measure of resistance of an aggregate to crushing under gradually applied compressive load. The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads.
