Concrete Aggregates

Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.

Crushed Sand vs. Natural Sand: Make the Right Choice!

Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Crushed sand contains a larger amount of micro- fine particles. This can affect the strength of concrete.

Concrete Sand | Southern Crushed Concrete

Concrete Sand from Southern Crushed Concrete is a fine aggregate that is used in the production of concrete or mortar. Concrete sand is crushed in a quarry then filtered to ensure no large rock fragments are left behind. When mixed with cement and water, a grout is formed that fills the voids between the coarse aggregate.

5 The concrete must be well compacted around the bars. 6 Concrete should be at least C20 or 1:2:4 nominal mix and have a maximum aggregate size of 20mm. Concrete floors are sometimes reinforced with welded steel mesh or chicken wire, placed 25mm from the upper surface of the concrete, to limit the size of any cracking.
