Gradation and Size - Pavement Interactive

Refers to a gradation that contains only a small percentage of aggregate particles in the mid-size range. The curve is flat in the mid-size range. Some PCC mix designs use gap graded aggregate to provide a more economical mix since less sand can be used for a given workability. HMA gap graded mixes can be prone to segregation during placement.

Effect of Fineness of Sand on the Cost and Properties of ...

In the present study we have selected M30 Grade of concrete mix. To find out the effect of fineness modulus (FM) of sand on concrete, sand of different FM from 2.0 to 3.0 is chosen. Two sizes of coarse aggregate particles: i.e. 20 & 10 mm, which are generally used in standard concrete mix, were chosen for the investigations. Concrete Mix Selected:

Aggregate in Concrete - The Concrete Network
