· There are three main areas of processing with either of the three means of winning Aggregates and gravel (Crushing, Screening and Washing ) Crushing Crushing will largely depend on the percentage ...
· Also, in case of coarse aggregates, sample material should pass from quartering box in order to divide it into equal quarters. Quartering is done in order to reduce the size of field sample to test sample. The weight of fine aggregate sample after drawing should be minimum 500g where as in case of coarse aggregate, it should correspond to below table as per ASTM C136.
