What is meant by the grading of aggregates? Could you please explain the significance of grading in relation to aggregate performance, including its impact on strength, workability, and overall concrete quality?

The word “grading” refers to the diversity in size of the aggregates. Aggregates that have “good grading” or are “well graded” have the same % of each size stone. The goal is to get the maximum aggregate packing density within a mix that still allows the cement to bond to the aggregates and cure properly, since its the aggregates that give concrete its high compressive strength.
