Physical Prosperities of Aggregate Grading Grading is the particlesize distribution of an aggregate as determined by a sieve analysis using wire mesh sieves with square openings As per IS2386Part1 Fine aggregate 6 standard sieves with openings from 150 μm to 475 mm 150 μm 300 μm 600 μm 118mm 236mm 475mm

To obtain good quality concrete using recycled aggregate it is necessary to follow the minimum requirements defined by the respective Building Standards Acceptable properties of aggregates are an elemental base for concrete quality however adequate

This gives a stronger and denser concrete Rounded aggregates give a more workable mix Angular aggregates make concrete harder to place work and compact but can make concrete stronger STORAGE Aggregates should be stored where they will stay clean separated from other materials and dry If the aggregates are very wet use less water in the mix
