Grading of Aggregat Grading of Aggregates is one which is made up of stones of different sizes, ranging from large to small inclusive of sand so as to have minimum of air voids and that will have maximum density when mixed togetherIn grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate...
