Fine Aggregates: Types, Properties & Uses in construction

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 …

Aggregate Properties

Typically, coarse aggregate sizes are larger than 4.75 mm (5 mm in British code), while fine aggregates form the portion below 4.75 mm. A maximum size up to 40 mm is used for coarse aggregate in most structural applications, while for mass concreting purposes such as dams, sizes up to 150 mm may be used. Fine aggregates, on the other hand, have particles up to a minimum size of 0.075 mm. Typical …

Practical Grading of Aggregates | Concrete Technology

Zone II represents medium sand, generally suitable for the standard 1:2 fine to coarse mix, when the maximum size of coarse aggregate is 20 mm. The choice of correct proportion is particularly important as the grading of the sand approaches the fine outer limit of zone 4 or the coarse outer limit of zone I.

ACI Mix Design – Pavement Interactive

In general, ACI recommends that maximum aggregate size be limited to 1/3 of the slab depth and 3/4 of the minimum clear space between reinforcing bars. Aggregate larger than these dimensions may be difficult to consolidate and compact resulting in a honeycombed structure or large air pockets.
