Aggregates are then designated as being either G C coarse G F fine or G A allin. Aggregate is classed as coarse if D is greater than 2mm fine if D is less than 2mm and allin if D is less than 45mm and d is 0. Next the required minimum percentage passing D is given followed for coarse aggregates only by the maximum percentage

Sieve Analysis Of Aggregates Civil Engineering

Sieve analysis helps to determine the particle sie distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS 2386 Part I 1963. In this we use different sieves as standardied by the IS code and then pass aggregates through them and thus collect different sied particles left over different sieves.

Coarse aggregates are any particles greater than 0.19 inch but generally range between 38 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit river lake or seabed.

The sie of the aggregate bigger than 4.75 mm is considered as the coarse aggregate i.e. basically all other aggregates which are retained on 4.75mm IS sieve while sieve analysis is performed. According to sources of coarse aggregates it can be further classified as a Uncrushed Gravel or Stone It results from natural disintegration of rock.
