Components of concrete are essential. These act like inert concrete material. Two main types of cement aggregates are fine aggregates and coarse aggregates. They are graded based on the dimensions of the composite molecules, according to their name.
Fine Aggregate vs Coarse Aggregate
There are major differences between fine and coarse aggregates. Description, particle length, grades, origin, substrate, concrete features, uses, etc. are the main reasons for the major differences between deep and shallow base. The table below shows the main discrepancies between the finest and coarse aggregates:
| Sl. No | Scopes | Fine Aggregate (FA) | Coarse Aggregate (CA) |
|---|---|---|---|
| 1 | Definition | Good aggregates in the building are low fillers | Ground aggregates in construction are larger size filler materials. |
| 2 | Size of Particles | Fine aggregates are particles which pass through a sieve of 4.75 mm and retain a sieve of 0.075 mm. | Coarse aggregates are particles which hold on to a sieve of 4.75 mm. |
| 3 | Materials | Fine aggregates in cement are used for gravel, surki, screens of soil, burnt mud, cinders, fly ash, etc. | Brick chips, stone chips, gravels, caillouxes, clinkers, cinders, etc are used as rough cement add-ons. |
| 4 | Sources | The primary sources of fine aggregates include river sand and machine sand, crushed rock sand and crushed gravel sand. | The most common sources of coarse aggregate were dolomite aggregates, broken gravel and concrete, normal disintegration of soil. |
| 5 | Surface Area | Good aggregates have a greater surface area. | Less than fine aggregates is the coarse surface area. |
| 6 | Function in Concrete | The voids between the soil material were filled with a fine product. | The ground aggregate acts as inert concrete filler material. |
| 7 | Uses | In mortar, plaster, concrete, filling of pavement layers, etc., fine aggregates shall be used. | Coarse aggregates are used primarilya in concrete, ballast for railways and so on. |
