Crushing test

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 1). Dry aggregates passing through 12.5 mm sieves and retained 10 mm sieves are filled in a cylindrical measure of 11.5 mm diameter and 18 cm …

It should then be removed from the oven, cooled and weighed (Weight ‘B’). Formula used is Water absorption = [(A – B)/B] x 100%. Two such tests should be done and the individual and mean results should be reported.

  • Fineness Modulus of Coarse Aggregates and its Calculation

    Let us say dry weight of coarse aggregate = 5000g. Values after sieve analysis are. Therefore, fineness modulus of coarse aggregates = sum (cumulative % retained) / 100 = (717/100) = 7.17. Fineness modulus of 7.17 means, the average size of particle of given coarse aggregate sample is in between 7th and 8th sieves, that is between 10mm to 20mm.
