What does the Specific Gravity of Fine Aggregate, Absorption of Fine Aggregate, and Surface Moisture of Fine Aggregate matter to engineering? and how it is essential in concrete.
What does the Specific Gravity of Fine Aggregate, Absorption of Fine Aggregate, and Surface Moisture of Fine Aggregate matter to engineering? and how it is essential in concrete.
Specific Gravity of Fine aggregate:
It is the ratio of the weight of unit volume of Fine aggregate at a certain temperature to the weight of an equal volume of distilled water at the same temperature.
Specific gravity value is used in mix calculation to obtain the weight of the fine aggregate on the concrete mix.
Absorption of Fine aggregate:
Aggregate can contain some water, once after calculating the absorption of fine aggregate that percentage of water content will be removed or reduced from the weight of the fine aggregate on the concrete mix.
After reduction, that the corrected weight or volume of aggregate will be used for mix design.
Because water absorption on the fine aggregate will increase the water content in the concrete mixture, which leads to segregation and more voids, which eventually leads to structure failure.
