How do aggregates affect concrete strength?

Accordingly, how does the fineness modulus of aggregates affect the strength of concrete? Fineness Modulus is an indication grading of particle size. More the value of FM more coarser the aggregate is. Regarding your question, FM varying from 2.0 mm to 3.5 mm is labelled under fine aggregate while above it as coarse aggregate.Strength does not only depend on fineness Modulus of aggregate.
