size classification of aggregate

  • Sieve analysis - Wikipedia

    A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering 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.

    Based on the grain size, the aggregates are classified into two types. Fine Aggregate. Coarse Aggregate. The fine aggregates are used in concrete as a filler material to fill the voids. The coarse aggregates are used in concrete to develop the strength of the element. The difference between the fine & coarse aggregate are listed below.
