Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix,
Effect Of Coarse Aggregate Size And Grouting Process

Neville proposed the use of coarse aggregates of sizes smaller than 38 mm, with the aggregates being gap-graded and of multiple sizes [13]. Later, the minimum size of coarse aggregates of 10 mm was suggested by Orchard [14]. However, the grouting process and the grout determine the minimum size of the coarse aggregates used or vice versa [3].

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
