size of coarse aggregate for concrete 1 2 4

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.
