Aggregates for Concrete
aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete’s freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed
(PDF) Concrete with Recycled Glass as Fine Aggregates
Concrete with Recycled Glass as Fine Aggregates. Diverse concrete properties were tested in fresh and hardened states with three concrete grades; that is, with compressive strengths of 30, 45, and 60 MPa (4350, 6525, and 8700 psi). The incorporation of glass sand showed no significant influence on fresh or mechanical properties of concrete.
Concrete using agro-waste as fine aggregate for ...
1.1. Agricultural wastes used as a fine aggregate replacement in concrete. The Agricultural wastes used as fine aggregate in concrete are sugarcane bagasse ash, groundnut shell, oyster shell, sawdust, giant reed ash, rice husk ash, cork and tobacco waste.
Concrete aggregate alternatives - Appropedia: The ...
Cement is only one of the five ingredients used in a concrete mixture. With proper ratios of cement, rock, fine aggregate, air, and water, the EPA further cites that the previously mentioned amount of cement would be enough to produce 14 - 18 Gt of concrete making it the …
What are other alternatives for aggregates in concrete ...
One benefit to the addition of this alternative is the stone keeps the concrete from shattering in failure. Workability and mechanical properties of crumb-rubber concrete. Glass: Crushed glass can also be used as an alternative to aggregate in concrete and this type of concrete is known as Glasscrete.

2.2 Fine Aggregate Fine aggregate was obtained from the local source and falls under zone III. Fine aggregate is confirming to IS 383: 1970. It passes through 4.75 mm size of IS sieve having a specific gravity of 2.67. 2.3 Coarse Aggregate Coarse aggregate was obtained from local sources graded from 20 mm to 10 mm. It is confirming IS 383: 1970.
Aggregates for Concrete
More performance tests are also used to test aggregates in concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special
3 Aggregate Properties - IN.gov
The best aggregates to use for strength are crushed stone or crushed gravel. Crushed aggregate have irregular, angular particles that tend to interlock when compacted or consolidated. The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place. To improve the workability, many mixes
Different Types & Sizes of Aggregate for Concrete ...
Aug 11, 2018 · It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. SIZES OF AGGREGATE
Fine Aggregate: Definition, Size, Density and Properties ...
Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle shape and surface texture, abrasion ...

TEST SAMPLE 7.1 Reduce field sample by use of a sample splitter or by quartering according to ITP 248, to obtain approximately 2500g of fine aggregate. Place sample in a suitable pan or
ALTERNATIVE SOURCES OF AGGREGATES
Nevertheless, in many parts of the world such material is a major source of fine aggregate. In Jamaica, ‘stone dust’ is produced as a by-product of limestone quarrying and is used, principally, in concrete block making and in asphalt products. The quality of the ‘stone dust’ is, however, variable and may perform poorly as fine aggregate.
