Fine aggregate means the aggregate which passes through 475mm sieve To find the fineness modulus of fine aggregate we need sieve sizes of 475mm 236mm 118mm 06mm 03mm and 015mm Fineness modulus of finer aggregate is lower than fineness modulus of coarse aggregate

The higher the value of FM the coarser the aggregate Generally a lower FM results in more paste making the concrete easier to finish However FM does not define the grading curve and different gradings could have similar FMs (Suprenant 1994)
