How fine aggregate affects the mix design of concrete

Oct 08, 2019· Fine aggregate requires more water in a concrete mix than coarse aggregate as it has a larger surface area. Moisture content of fine aggregate. The moisture content of sand is a crucial factor in determining the water to cement ratio. All aggregates contain some moisture, but sand is able to retain more moisture than crushed stone, for example.

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

Aggregates Portland Cement Association

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. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design. Fine aggregate moisture []

What is Fine Aggregate? FA Types used in Construction

The aggregates passing 4.75 mm tyler sieve and retained on .075 mm sieve are classified as Fine Aggregate. Types of Fine Aggregate. Usually, sand, crushed stone, and crushed bricks are used as fine aggregate in concrete or pavement construction. Sand. Sand is an important engineering material. In concrete works, sand is used as a fine aggregate.

This gives a stronger and denser concrete. Rounded aggregates give a more workable mix. Angular aggregates make concrete harder to place, work and compact, but can make concrete stronger. STORAGE Aggregates should be stored where they will stay clean, separated from other materials and dry. If the aggregates are very wet use less water in the mix.

Suitability of Quarry Dust as a Partial Replacement of

To overcome this problem, present study is focused on the suitability to utilize the quarry dust in Self Compacting Concrete (SCC) partially as fine aggregate with the natural fine aggregates. In this work, quarry dust is used as replacement of sand in a different level (0%, 15%, 30%, 45% and 60%) for producing the SCC.

Difference Between Fine and Coarse Aggregate Civil

Dolomite aggregates, crushed gravel or stone, natural disintegration of rock are the major sources of coarse aggregate. 5: Surface Area: The surface area of fine aggregates is higher. The surface area of coarse aggregate is less than fine aggregates. 6: Function in Concrete: The voids between the coarse aggregate are filled up by fine aggregate.
