Sieve analysis helps to determine the particle size distribution of the coarse and fine is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.
The first stage of aggregate processing involves quarrying where a large deposit of desirable aggregate is identified and extracted from the ground. Hardened substances are either blasted or cut into smaller manageablesized rubble and transported by truck or conveyor belts to the processing area.

Coarse aggregates are particulates that are greater than The usual range employed is between and in diameter. Fine aggregates are usually sand or crushed stone that are less than in diameter. • Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete.
15. In the case of coarse / fine aggregate mixtures, the minus mm (No. 4) may be distributed among two or more sets of sieves to prevent overloading of individual sieves. Calculations The total mass of the material after sieving, for both coarse and fine portions should check closely with the original mass of sample placed on the sieves.
Reclaimed asphalt aggregate (RAA) which is a product of a specialized method to produce reclaimed coarse aggregate and recycled asphalt granules from waste asphalt concrete and concrete dust. 6. Glass cullet sand. 7. Scrap tyre chips and crumb rubber aggregate. 8. .

to the early aged bond strength of the mortar and the coarse aggregate. Factors relative to the construction process were found to be important in terms of the rate of water loss from the surface of the pavement during the hardening process. Polyethylene curing was found to significantly reduce the formation of the delaminated fracture surface.

Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and pavement. Homes, offices, warehouses, shopping centers, and workplaces all require foundations composed of aggregate, as well as concrete footers, asphalt parking lots, manufactured bricks, blocks and poured walls.
Headquartered in Eau Claire, Wisconsin, RB Scott Company, Inc. has the experience and the expertise, in partnership with our vendors, to provide standard or customized portable plants, modular or stationary stands, and entire portable or stationary aggregate processing systems.
1. Size of Aggregate. Crushed concrete shall be processed to reach suitable sizes. The crushing method (mechanical or manual) of concrete to produce coarse aggregate for the production of new concrete is one of the factors that affect the strength of the concrete. It is reported that, coarse aggregate which comply with standards can be produced.
Coarse aggregate samples can be split at any moisture. Gilson strongly recommends using mechanical sample splitters to reduce bulk samples to testing size. Mechanical splitters use chute riffling for faster and more efficient processing of aggregate specimens and produce a representative sample that is up to five times more accurate than manual scoop or coneandquarter methods.
