Fine Aggregates: Types, Properties & Uses in construction

Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and coarse fractions. Qualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc.

Shape, Size Coarse Aggregates

Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve.
