Recycled Concrete Aggregate

Recycled Concrete Aggregate

Fine recycled concrete aggregates (RFAs) contain not only the parent river sand but also a large amount of old cement matrix which exists independently as fine particles (these aggregates having a very highabsorption capacity) or as adhered mortar on the surface of the old river sand particles. The existence of the old adhering cement matrix has resulted in the RFA having smaller density ...

Fineness Modulus of Sand (Fine Aggregates) – Calculations, Values .

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus. Fine aggregate means the aggregate which passes through sieve. To find the fineness ...

Crushed stone dust or natural sand is the fine aggregate chiefly utilised in the concrete mix. Sand may be collected from the river, sea, lake or pit. Still, when used in the concrete mix, it should be adequately cleaned and tested to determine that the total percentage of silt, salts, clay and other such organic stuff does not pass the defined limit.

Aggregates

Aggregates

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. 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.
