· Different types of processed wastes are recommended by IS 383-2016 for use in concrete as aggregate such as slag aggregates, C and D waste and recycled concrete aggregates. At present in India, it is a common scenario that lots are broken vitrified tiles are found unused in the production and application sites and are dumped into the city ...
· 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% of the volume of concrete. Aggregate properties significantly affect the workability of ...
Strength and durability. Aggregates shall not contain any harmful material, such as pyrites, coal, lignite, mica, shale or similar laminated material in any given quantity as to affect the strength of durability of the concrete. Manufactured Sand as fine aggregates in Concrete (grades of M20, M30) and Cement mortars (ratio 1:4 and 1:6).
2 · If iron is used as fine and coarse aggregate, the density will be 5820 kg/m3. Heavy natural aggregates are used in heavyweight concrete. These natural aggregates include barites and magnetite. If barites are used, the density will be around 3,500 kg/m3. It is possible to use manufactured aggregates as well, such as iron or lead shot.
Key points. • 'Aggregate' is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.
Aggregate provides much of the strength, thermal and elastic properties of concrete, as well as dimension and volume stability. Including aggregate in the mix can also control shrinkage and prevent cracking. A specific aggregate (or combination of aggregate) is selected for its durability, strength, workability and ability to receive finishes ...

Ian Sims, Bev Brown, in Lea's Chemistry of Cement and Concrete (Fourth Edition), 1998. Design of processing plants. The objective of any concrete aggregate processing operation should be the production of good-quality, 'clean' coarse and fine materials in the normal range of sizes. The types of equipment used and the flow design of the plant is more or less completely dependent …
