SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation (particle size) of the aggregate, it is necessary that they be sampled correctly The results of testing will re" ect the condition and characteristics of the aggregate ,
Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number It is calculated by performing sieve analysis with standard siev The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate
SIEVE ANALYSIS Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregatThis is done by sieving the aggregates as per IS: 2386 (Part I) – 1963 In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over .
