Sieve analysis for fine aggregate is a procedure used in civil engineering to determine the fine aggregate's fineness modulus and grain size distribution by allowing the material to pass through a series of sieves of progressively smaller mesh sizes. After sieving the fine aggregate, weighing the retained amount of material in each sieve as a ...

Sieve analysis or a gradation test is an important method for assessing the particle size distribution of granular material. Particle size influences material properties like flow and conveying behavior (for bulk materials), reactivity, abrasiveness, solubility, extraction and reaction behavior, taste, compressibility, and many more.

Coarse aggregate is the one retained on 4.75 mm IS Sieve. When the aggregate contains sizes differently in suitable proportions, it is called graded aggregate. The workability of concrete is also improved with well graded aggregate. Single size aggregates make the concrete harsh and does not work well with trowel and between the cables, strands ...
