Oct 03 2019 Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load Aggregate Crushing Value Test is important to test to be performed on aggregate The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.Dec 19 2019 If the aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate Whereas if the crushing value is 35 or above it would normally be considered as weak aggregate After performing the test the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.Read More
Jan 25 2021 Aggregate Impact Value = (W2 W1) 100 Aggregate Crushing Value Acceptance Limits For aggregate use to resist wear Max 30 percent For non wearing surface the value is 45 percent Max Lower limits if used shall provide better performance against gradually applied compressive load Aggregate Crushing Value Test Form.Jan 13 2011 Aggregate Crushing Value 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 Value.Read More
The aggregate crushing value is obtained by the following expression – Where W 1 = Total weight of dry sample W 2 = Weight of material passing 2 36 mm I S sieve The aggregate crushing value provides an indirect measure of the crushing strength of the road aggregate The strong aggregates possess low aggregate crushing value.Calculate Aggregate Crushing Value The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage the result being recorded to the first decimal place Aggregate Crushing Value = W B W A 100 Where W A is weight of surface dry sample.Read More
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates For this reason a simple test known as 10 percent fine value is introduced When the aggregates crushing value become 30 or higher the results are likely to be inaccurate Aggregate Crushing Load (Source The Constructor Civil Engineering Home).Oct 01 2016 The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads Also read Crushing Value Test of Aggregates 13 Impact Value The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact.Read More
