fine aggregate for concrete

Aggregates for Concrete
Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi- mately 60 to 75%

Sand: The Fine Aggregate SpringerLink
That portion of an aggregate passing the 4.75 mm sieve and predominantly retained on the 75 µm sieve is called “fine aggregate” or “sand,” and larger aggregate is called “coarse aggregate”. Coarse aggregate may be available in several different size groups, such as 4.7–19 mm, or 19–37.5 mm. Fine aggregates generally consist of ...

Effect of Using Copper Tailings as Replacement of Fine Aggregate
As shown in Fig. 2, if the fine aggregate is all tailings, the fluidity of concrete mixture will be poor, and the dry shrinkage deformation of concrete will be serious in the later stage. To avoid the above situation, this experiment adopts the method that copper tailings gradually replace natural sand, which is, tailings gradually replace natural
