Other sand is used as an abrasive in sandblasting and to make sandpaper. Sand is a significantly important material for the construction but this important material must be purchased with all care and vigilance. Pit Sand (Coarse sand) Pit sand is classified under coarse sand which is also called Badarpur in common language.

For construction, sand is commonly used as an ingredient for concrete, with numerous options available depending on what a project needs. Knowing which type is appropriate for your project is crucial, as each type of sand varies in strength, looks, bulk, and price. Concrete Sand This type of sand is usually coarse and made of your usual aggregates.

The uses of fine aggregate is; it is a small size of filler materials that is used in construction. By fine aggregate The voids between the coarse aggregate are filled up. This is an another uses fine aggregate. The uses of fine aggregate are, in concrete, plastering, as mortar, filling of road pavement layers, etc. it can be easily used.

Based on the grain size of the particle, sand is classified as Fine Sand (0.075 to 0.425mm), Medium Sand (0.425 to 2mm), and Coarse Sand (2.0 mm to 4.75mm) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand. Fig. Grain size distribution of sand used in building construction.

Coarse-grained soils have 50% or less material passing the No. 200 sieve. Fine-grained soils have 50% or more material passing the No. 200 sieve. Engineering properties such as strength and compressibility of coarse-grained soil are governed by the grain-size of the particles and their structural arrangement.

Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and coarse fractions. Qualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc.

In the construction industry, aggregates are used in concrete considering its economic factor and its strength which it is provided to concrete. Coarse aggregates are used in different ways in the construction industry.The aggregates are also used as ballast in road and railway works to resist the overall load, to distribute the load properly to the soil base, and drain off the rainwater

Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as

Sources of Sand Used in Construction. There are three main sources of sand used in construction, river sand, crushed sand, and pit sand. River sand is usually obtained from river banks, while pit sand is obtained by digging deep pits. On the other hand, crushed sand is obtained by the strategic crushing of rocks (to fine particles) in quarries.

The sand which is passing through the 3.175 mm sieve is called coarse sand. This size of sand is mostly used for masonry works. Pit sand is mostly coarse in nature. Fine Sand:-Sand passing through the 1.5875 mm sieve is called fine sand. Fine sand is mostly used in plastering works for better finish. Classification based on grain size:-

With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.

Fine Aggregates: They are the aggregate particles that pass sieve #4 but retain on sieve #200. Fine aggregates include a wide range of particle sizes. Specifically talking about sands, the grain-size distribution further classifies sand into coarse sand, medium sand, and fine sand.

Types of Fine Aggregate. Usually, sand, crushed stone, and crushed bricks are used as fine aggregate in concrete or pavement construction. Sand. Sand is an important engineering material. In concrete works, sand is used as a fine aggregate. Sand is a form of silica (quartz) and may be of argillaceous, siliceous or calcareous according to its ...
