    Flaky Particles Flaky particles are those whose least dimension is times lesser than the mean size. Thickness of these particles are comparatively smaller than the other two dimensions. Maximum allowable limit of the flaky particles in the mix is 30%. If it exceeds this value then the mix is considered unsuitable for construction purpose.

    The method is used for larger sized aggregate such as 20, 14 and 10mm. The accuracy of the result is based on 2mm slot variations due to aggregate size. The method is used for the smaller sized aggregates such as 7 and 5mm. This form of the test is based on 1mm slot variations as the smaller size packs differently and gives a closer ...

    Aggregate impact value, AIV, aggregate crushing value, ACV, and 10 per cent fines loads, however, are aggregate size dependent. Tests on larger aggregate sizes give higher test values, whereas tests on smaller aggregate sizes give lower values than test results for standard size aggregates. For each rock type there is a different set of sieve ...
