Note 1 for every ±005 change in wc the coarse aggregate proportion is to be changed by 001 if the wc is less than 05 standard value volume of coarse aggregate is required to be increased to reduce the fine aggregate content if the wc is more than 05 volume of coarse aggregate is to be reduced to increase the fine aggregate
Note in the above table the proportion of the fine to coarse aggregates should be adjusted from the upper limit to lower limit progressively as the grading of fine aggregates becomes finer and the maximum size of the coarse aggregate becomes larger graded coarse aggregate shall be used ie for an average grading of fine aggregate that is zone ii is 383 table
Partially crushed stone or gravel which is obtained by blending of above two types the graded coarse aggregate is defined by its nominal size ie 40 mm 20 mm 16 mm 125 mm etc for example a graded aggregate of nominal size 125 mm means an aggregate most of which passes the 125 mm is sieve because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing
