Fine aggregate; Coarse aggregate; Fine Aggregate When the aggregate is sieved through a 4.75mm sieve, the aggregate passed through it called fine aggregate. Natural sand is generally used as fine aggregate, silt and clay also come under this category. The soft deposit consisting of sand, silt, and clay is termed as loam.

Natural aggregate consists of manufactured crushed stone and sand created by crushing bedrock, or naturally occurring unconsolidated sand and gravel. It is a major component of asphalt and concrete and is required in streets, highways, railroads, bridges, buildings, sidewalks, sewers, power plants, and dams—just about every part of the built environment.

Gravel rubble is a nonmetallic, granular material, which is obtained by crushing or sieving of quarry (rock) rocks. It is frost-resistant, however, its strength is somewhat lower than that of crushed granite, but this does not prevent it from being used in many types of construction work. The gravel gravel is divided into two types: sea and river.

1.1 Definition. Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone. Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations. 1.2 History. 1.2.1 Origin.

RSFM = Rock (select) fines, manufactured. Selectively quarried rock crushed into sand sized particles. G = Gravel. Any natural deposit of unconsolidated gravel. L = Lightweight aggregate. Typically a thermally expanded shale that is vitrified and has high porosity and low specific gravity. R = Rock (also known as bedrock, stone, or ledgerock).

Aug 11, 2018· When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category. The purpose of the fine aggregate is to fill the voids in the coarse aggregate and to act as a workability agent.

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
