Using grading curves it would appear that an aggregate with 52 per cent passing the 9.5 mm sieve is required with a sand that all passes the 4.75 mm sieve. There is a very large local market for 14 mm maximum size concrete, however interpolation suggests that the grading of a suitable aggregate would be about 70 per cent passing the 9.5 mm sieve.

A sieve analysis (or gradation test) is a practice or procedure used to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
