Grading of aggregate. ... (BS 882:1992) For example: a 20 mm single size aggregates means an aggregate most of which passes through a 20 mm sieve and major portion is retained on 10 mm sieve. Moisture content Important factor when developing the proper W/C ratio.
Continuously graded aggregates for concrete contain particles ranging in size from the largest to the smallest; in gap-graded aggregates some of the intermediate sizes are absent. Gap-grading may be necessary in order to achieve certain surface finishes. The sieves used for making a sieve analysis should conform to BS 410 or BS EN 933-2.
