Concrete Aggregates

Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm. Fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain particles up to 150 mm.

The Beginners Guide to Coarse Aggregate

Basically, aggregates are used as an economical option to lower down the cost of concrete usage. In simpler words, we can say that these are the fillers used in concrete mix. The majority of construction applications use different coarse aggregate size, but it is essential to keep the characteristics in mind to get uniform and strong output.

Coarse Aggregate

 · To achieve certain workability and maximum size of aggregate the factor of maximum aggregate size controls water demand and reduces the surface area of coarse aggregate increases. If the surface area is higher than water demand to coat the particles and generate workability is greater and for a given weight, higher the maximum size of aggregate and lower is the surface area of coarse aggregates.

Bulk Specific Gravity

Coarse aggregate angularity is determined by computing the percentage of coarse aggregate particles with fractured faces. A sample of coarse aggregate is divided into three groups. One group contains all the particles with no fractured face, the second group contains all particles with one fractured face, and the third group contains all particles with two or more fractured faces.
