Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
plastic wastes as fine aggregates in concrete as an effective way to deal with the ... the ill-effects of sand extraction and the problems related to disposal of plastic ... environment were solved by using artificial sand, but due to the high cost it is...
aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 5-6 shows these limits for fine aggregate and for one size of coarse aggregate.

The Suitability Of Limestone Aggregates For Use In Structural Concrete. The following is an excerpt of a presentation made by Mr. Gordon Hutchinson at a seminar hosted by John's Hall Aggregates Limited entitled "The future of Construction Aggregates" held on June 13, 2012 at the Lecture Theatre, Montego-Bay Community College.
The slabs, using Artificial sand, are more leak proof than by river sand. Now a days, in construction of roads, buildings, dams, canals, etc., cement concrete plays an important role. Concrete is an artificial stone resulting from hardening of rationally chosen mixture of binding material, water and aggregate (Sand and crushed stone or gravel).
crete made up of grit when compared with the concrete made up of Artificial Sand and Natural Sand. Use of grit as a fine aggregate in con-crete draws serious attention of researchers and investigators. Index Terms— Artificial Sand, depletion of sources, environmental transportation, fine aggregate, Grit, Natural Sand, replacement product.
position. The use of natural sand in conventional concrete has become of vital importance which is scarce to obtain. Sand is basic concrete making construction material required in large quantities. Manufactured sand is one among such materials to replace river sand which can be used as an alternative fine aggregate in mortars and concrete.
The synthetic aggregate for use in concrete is a composite material of recycled plastic having a filler encapsulated in the plastic. The synthetic aggregate includes between 30% and 50% recycled shredded plastic, the balance being filler. The plastic may be linear low-density polyethylene (LLDPE). The filler can include red sand, fly ash and quarry fines.

The best aggregates to use for strength are crushed stone or crushed gravel. ... and the fine aggregate particles are ... such as mineral deposits formed in sand and gravel by ground water, or may be artificial, such as dust formed by crushing and handling. Generally when the aggregates are us ed in hot mix asphalt or portland cement
Tests were carried out on cubes, cylinders and unreinforced beams to study the mechanical properties of concrete using foundry sand and compared with concrete with artificial sand as fine aggregate. Artificial sand was replaced with five percentage (0%, 5%, 10%, 15%, and 20%) of WFS by weight.
and sand, use of super plasticizers and change water content. (1998) Shukla et al. investigated the behavior of concrete made by partial or full replacement of river sand by crushed stone dust as fine aggregate and reported that 40 percent sand can be replaced by crushed stone dust without effecting the strength of concrete.
for natural sand is by crushing natural stone to get artificial sand of desired size and grade . The promotional use of artificial sand will conserve the natural resources for the sustainable development of the concrete in construction industry . Artificial sand is a process controlled crushed fine aggregate …
Sand manufactured by Vertical Shaft Impactor is of cubical shape. Such sand can be used for all types of construction work, Concreting, Plastering etc and is better substitute to river sand. V.S.I. Crushers is a most economical machine for Crushing Stone in Cubical shape and manufacturing artificial sand.

Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as
