2021-6-4 · Coarse aggregate of 20mm maximum size is used in Reinforced cement concrete work of all types of structures. This is obtained by crushing the stone boulders of size 100 to 150mm in the stone crushers. Then it is sieved and the particles passing through 20 mm and retained on 10mm sieve known as course aggregate.
2021-12-13 · With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.
2020-7-31 · 7.2 Fine aggregate Fine aggregates are materials having a nominal size of 5 mm or less and consisting of one or a combination of the following: a) source rock aggregate, including crusher dust generated from tertiary crushers (such crusher dusts may be washed and/or classified prior to use), resulting from the manufacture of the coarse aggregate.
2016-10-15 · The Glass Powder is used as 20% replacement of the cement and Stone Dust as the partial replacement of Fine Aggregate from 0%, 10%, 20%, 30% and 40%.

2021-8-9 · amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by absolute volume (45% to 60% by mass). Rounded aggre-gate, such as gravel, requires slightly lower values, while crushed aggregate requires slightly higher values. Fine aggregate content is usually 35% to 45% by mass or
2014-10-11 · The replacement level of the fine aggregate (30, 40, 50, 60 and 70%) by stone dust was investigated. It is observed that the compressive strength is not affected much by replacement up to 40%; however, the flexural strength at all ages improved significantly at all the replacement levels. Keywords: Natural sand, fine aggregate, concrete, stone ...

Concrete composite material whose basic properties are related to the characteristic of constituent element, especially the aggregate. This research aimed to investigate the effect of replacing sharp sand with stone dust as an alternative to only river sand.
2015-4-30 · The replacement of fine aggregate with stone dust does not give any harm on strength, it gives beneficial results. But it badly affects the workability on increment level of stone dust. So for maintain workability the dose of concrete was increased which affect the setting time and nearly doubled with ...
Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and coarse fractions. Qualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc.
