Experiment no 02 crushing value. 1. Aggregate Crushing Value Test Experiment no: 02 Engr.Sayed Shajedul Hasan.; 2. Engr.Sayed Shajedul Hasan. • 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 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.Aggregate crushing test Strength of aggregate Vincivilworld

Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material (W 2) is expressed as percentage of the weight of the total sample (W 1) which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak Aggregate Crushing Value = 100(W2/W1) percent. where, W2 = Weight of fraction passing the appropriate 2.36 mm IS sieve, and. W1 = Weight of surface-dry sample. Final Verdict.

Properties of Recycled Aggregates SpringerLink

The aggregate crushing value is an indication of resistance of gradually applied compression load. Higher the aggregate crushing value, lower is the strength of the aggregate. Therefore, the resistance against crushing of recycled coarse aggregate obtained from all the three Sources is weaker than that of natural coarse aggregate.Consequentially, different crushing index can affect the performance on RAPC greatly. This paper focused on the sorts of recycled aggregates grouped by different crushing value, and some tests on compressive strength, flexural strength, elasticity modulus, porosity, permeability, frost resistance were conducted for 6 groups of RAPC Influence of crushing index on properties of recycled aggregates
