Types of Construction Sand

River Sand

River sand, also known as natural sand, is one of the most frequently used sand in construction. Due to its fineness, the texture of the sand has made it temporarily unavailable. River sand is a kind of natural sand because it is typically found near river banks and streams.

Another thing to consider when using River Sand is that the sand has a high Silica content, which should be checked before utilizing it in construction. The amount of silica in the sand must not exceed 5%. Using river sand has the advantage of requiring less water because it contains greater moisture content.

Pit Sand

Pit sand is a type of sand that occurs naturally in the earth’s crust and lies between 1 and 2 m below the surface. It’s composed of tiny, sharp-edged grains. One of its main characteristics is that it allows materials used in construction to adhere to each other.

While the River sand is often tainted with salts and silica, there are no such issues with Pit Sand since it is unadulterated salt that happens to be naturally present within the soil. If you want high-quality sand for your landscaping, pit sand may be a good option; however, only if the sand coarseness is by the rules.

Manufactured Sand

If you can’t locate River sand, manufactured sand is the finest option and is also known as eco-friendly sand. Manufactured sand is made by grinding the granites into a fine texture.

Manufactured Sand may be found in two forms. Granite can be crushed or blasted to produce this material and is good for plastering walls. To obtain the texture of natural River sand, these particles go through several stages of processing, including crushing, sieving, and washing.

Due to the scarcity of River sand, people have begun using higher quality Manufactured Sand more recently. It is also more ecologically responsible and sustainable than River sand.

Concrete Sand

Because it is a combination of several materials, concrete sand has a textured surface that is generally larger than other sands. Concrete sand has the greatest binding power and is one of the most commonly utilized sands in construction.

Masonry Sand

Mason sand (also known as masonry sand or mortar sand) is a kind of fine sand frequently utilized in building projects. This sand features uniform-sized grains, giving it an elegant appearance and feel. Mason sand is a type of construction aggregate that is used in masonry work. The finishing works around the outside are particularly important.

Fill Sand

This type of sand is primarily used to fill. It’s a mix of sand grains and aggregates, and it’s a major base material for concrete casting, large hole filling, paving, and other similar projects. Its capacity to empathize makes it an unbeatable foundation material for construction. Fills sand is also much more advantageous when constructing in wet regions since it acts as a backstop to help with drainage issues around septic tanks.

Sand Density

• The density of loose sand is 1442 kg per m3. The average density of dry sand is 1602 kg / m3.
• The density of packed sand is calculated to be 1682 kg per m3.

Bulking of Sand

The term “sand bulking” refers to an enlargement in sand volume as a result of an increase in moisture level. A layer of water is formed around the sand particles, pushing them apart and causing the volume to rise.

If the sand is dry, it’s known as bulking. The quantity of water in the sand grains affects the growth of dry sand. The increase in moistness in sand causes it to bulk up. The quantity of water present within the sand determines its swelling capacity. Sand that has been dried may expand by 5% or more with just 5% to 8%. For coarse sand, this increase is approximately 20 to 40 percent; for fine gravel, however, it can be as much as 50%.

The moisture in the sand determines how much sand is bulked. However, as the film around the sand particles thickens and breaks as more water is added to wet sand, the sand particles get closer together. The volume of dry sand exactly equals that of fully full water.
