Aggregates SlideShare

Jan 14, 2015Aggregates. Classification of aggregates Based on size  classified into 2 categories fine aggregates those aggregates which pass through 4.75 mm sieve or aggregates with size less than 5 mm. Coarse aggregates those aggregates Passing through 75 mm sieve and entirely retained on 4.75 mm sieve OR those aggregates with size greater than 5 mm.

Classification of Aggregates Civil Snapshot

Aggregates whose particles do not pass through 4.75mm IS are termed as coarse aggregates. Most commonly used coarse aggregates are crushed stone, gravel; broken pieces of burnt bricks, etc. a. Crushed stone It is an excellent coarse aggregate and is obtained by crushing granite, sand stone or grained lime stone and all types of stones.

Aggregate in Concrete The Concrete Network

The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired. The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate.

What are the Different Types of Gravel? (with pictures)

Sep 05, 2019Gravel is often used in roadwork and landscaping projects. Most is naturally formed, usually by moving bodies of water, but some, like crushed stone, is man made. Other types include bank, bench, river run, fine, and pay gravels. Bank gravel, or bank-run gravel as it is sometimes called, is often mixed with sand or some type of clay.

Grading of Aggregates Aggregate Grading The

In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.
