Concrete aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural state or crushed, according to its use and application.

wide variety of product from mining and crushing of rocks form primary raw materials in many industrial applications (Ellen, 2010). Aggregates have an amazing variety of uses. Imagine our lives without roads, bridges, streets, bricks, concrete, wallboard and roofing tiles or without paint, glass, plastics and medicine.

Using natural sand as fine aggregates in concrete production has been the conventional element used in the industry for several decades. However, this excessive use can result in the depletion of locally available sand [1,2].Current practices that consider sustainability as a priority are agreed on finding ways to reuse the waste in order to …

Coarse aggregate is a term used in construction to describe a type of material that is commonly used in the production of concrete. It is typically made up of various materials such as gravel, crushed stone, and recycled concrete. ... Fine Aggregates. The size of the fine aggregates is lesser than 4.75 mm. That is …

The cost of production of concrete has observed a sustained rise over a period of time and there has been an increasing shortage of fine aggregates, thus aggravating the situation further. Some serious concerns have been raised repeatedly over the detrimental effects of reckless extraction of fine aggregate from river beds.

Incorporation of fine recycled aggregates to replace materials in cement raw meal. • Production of 7000 tons of clinker with fine recycled aggregates at industrial scale. • Mechanical and durability investigation of C30 and C60 concretes with recycled cement. • Ranking of investigated concretes using a performance approach.

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."

Aggregate is an important raw material in the infrastructure construction industry. Aggregate is divided into fine aggregate (commonly known as sand, with a particle size between 0.15-4.75mm) and coarse aggregate (commonly known as stone, with a particle size between 4.75-9.0mm).. The aggregate material is loose and granular in shape and …
