Following are the classifiion of aggregates based on size Aggregates are classified into 2 types according to size Fine aggregate Coarse aggregate Fine Aggregate When the aggregate is sieved through 4 75mm sieve the aggregate passed through it called as fine aggregate

Gradation – the fine aggregate or filler particles must be finely graded to prevent a harsh mix a stiff low flow mix usually resulting from a preponderance of granular material and have a sufficient range of finer size particles to provide flowability stability and minimal void spaces in the flowable fill mix
