Types of Sand in Bangladesh

Sand Types: Classification, Properties, Grain Size, and Applications.

Types of Sand in Bangladesh: Sand is a naturally occurring inorganic substance composed of granulated pebbles. It is of paramount importance in our daily routines and is regarded as one of the prerequisites for the development of infrastructures. 

Demands for high-quality sand provided by Mayfield Bangladesh:

Sand should be free of any particulates that could potentially disrupt its neutrality.
The sand utilized should be a well-graded mixture of coarser and finer granules, in accordance with the specifications of the most recent edition of IS 383 or an equivalent standard.
The fine sand used for plastering must have a modulus of at least 1.5, and white openings are preferred at a minimum of 4 percent.
The slit generally preferred is 4 percent, and the fine sand used in brickwork must not have a modulus less than 1.2 to 1.5.
The slit content must not be less than 4 percent, and coarse sand with a modulus of 2.5 to 3.5 is necessary for concrete works.
The organic matter should not be incorporated in this location.
The trace of earth units must not be present.

Sand Types and Classification

The classification of sand is as follows:  

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 the fiber size of the particle.
Sand is classified as Pit sand, River sand, Sea sand, and manufactured sand as a result of its origin.

The sand varieties that are most frequently employed are as follows:

Pit Sand:

This coarse sand is frequently encountered in a red-orange hue. It is protected by deep trenches that are excavated 1 to 2 meters beneath the surface of the soil.

The granules of pit sand are rough, angular, sharp, and harsh. It is a conventional choice for concreting due to its lack of ions and other impurities.

Sylhet Selection Sand:

Sylhet Selection sand is a fine sand that is caused by the corrosion of water currents.

derived from the banks and tributaries of rivers. In general, it is a shade of white-grey. The granules of river sand are smooth, rounded, and of a high quality, in contrast to pit sand.

Consequently, it is employed worldwide for a wide variety of construction applications, including plastering.

Sea sand:

Sea Sand, which is also referred to as offshore sand, is the sediment that has been eroded by seawater. It is protected from the littoral and is characterized by a distinctive brown hue.

The sea sand granules are of exceptional quality and possess a circular shape. Sea sand is composed of salt and other marine impurities that have the ability to absorb atmospheric moisture and produce humidity.

Consequently, it is disregarded in the context of concrete structure and engineering techniques.

Manufactured Sand:

Manufactured sand is a synthetic form of sand that is produced as an alternative to river sand in the construction industry. It is produced by compressing hard granite stones.

It is prepared with the necessary gradation of fineness, shape, surface smoothness, texture, and consistency, rendering it the most suitable sand for construction. This sand also enhances the strength of the concrete by minimizing segregation during placement, bleeding, honeycombing, voids, and capillary.

Moreover, its utilization also prevents the dredging of river beds to obtain river sand, thereby preventing disasters such as groundwater depletion, water scarcity, and a threat to bridge safety. Consequently, it is a more environmentally favorable alternative to other sands.

Sand sieve analysis:

A sieve analysis (gradation test) is a procedure or method that is employed to ascertain the compliance of particulate material with design, production control, and verification specifications by examining the particle size distribution.

The size distribution is frequently a significant concern when attempting to understand the material’s behavior during use.

Analysis of the sieve Procedure: Obtain a 500g sample of grit that has been oven-dried.
Determine the precise mass of the sample.
Prepare a stack of sieves and arrange the sieves with larger opening sizes (e.g., 600u, 300u, 150u, and 75u) above the sieves with smaller opening sizes (e.g., 4.75mm, 2.36mm, 1.18mm). A pan is positioned at the base of the container to capture the sand that has passed through all of the sieves.
Place the cover on the stack of sieves and pour the sand in from the top. Then, secure the stack in the sieve shaker and agitate it for 10 to 15 minutes.
The mass of the retained sand in each sieve should be measured after the sieve agitator is stopped.
