Mar 03 32 Flakiness and Elongation Test BS 812 Part 3 The type of rocks and the type of crushing machine highly determine the shape and size of the aggregates produced Elongated and flaky stones are normally not very suitable for road works since the shape and the size make them difficult to compact As such the flakiness and elongation test what do u mean by elongation flakiness of aggregate Answer / sowmiya be Elongation index is the by weight of particles whose greater dimension is greater than 4/5 of the mean dimension ELONGATION INDEX = wt of aggregate retained on specified gauge / total wt of aggregate taken

The flakiness index of course aggregate is defined in percentage by weight of aggregate particles and least dimension thickness of those particles should not be less than 06 times their mean area Flakiness index test is not applicable for aggregates sizes smaller than 63mmThe crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load 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 aggregat

how to improve flakiness index on a aggregate crushing plant Print how to improve flakiness index on a aggregate crushing plant VSI crushers are often used in the last stage of crushing in order to improve the shape/flakiness index of aggregate and NHAI calls for a total combined flakiness and elongation index of <30 One of the model in which pavement material can fail is by crushing under compressive stress A test is standardized by IS part IV and used to determine the crushing strength of aggregatThe aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing
