Sand is one of the primary materials used for construction to provide strength and durability to the building. Rigidity and strength are the two things that a structure needs and gravels and sands provide that. Sands can be easily compressed which is why they can be used in all types of flooring, grounding, and wall reinforcements.
Sand needs to be mixed with other materials to get its full strength and if its right amount is exceeded, it may become heavy. This will make the structure less resistant and stable. Let’s take a look at a few different types of sand used in construction:
- Concrete sand
- Pit sand
- Natural sand or river sand
- M-sand
- Utility sand
- Fill sand
Here are The Details of Different Types of Sand!
1. Concrete Sand

Concrete sand is made of crushed concrete and is used in asphalt and cement mixtures. While manufacturing concrete sand, concrete is crushed in the quarry before filtering to remove large fragments and huge rocks. Concrete sand is mixed with water and cement to form a solid mass that is used as a levelling base for walking paths, patios, and layers. This solid mass is also used to fill the voids in coarse aggregates.
It has comparatively smaller grains making it suitable for creating pavements. Its grains are, however, larger than the white sand so it can be used as filling material too. The texture and size of concrete sand are ideal for several applications that provide fundamental stability to a structure.
2. Pit Sand

The type of sand found 2 to 3 meters below the surface level in deep pits is called pit sand. Their superior binding property makes it an ideal component for construction. It consists of coarse, angular, sharp, and rough grains which provide the amazing binding feature of the sand.
They are orangish-red in colour because of iron oxides. The sand is free from salts so they do not absorb atmospheric moisture easily. Since there is no moisture in the sand, they provide compelling rigidity and strength to the building.
3. Natural or River Sand

River sand is gathered from the banks of streams and rivers. They are fine in quality and greyish white coloured. One of the finest sands, river sands are mainly used in masonry and concrete construction but also find their application in building blocks, bricks, plastering, and RCC.
The sand has a smooth texture and requires less water because of the more refined grains. River sands have moisture trapped in between their grains. Typically, a medium-quality type of river sand consists of 5% to 20% silt.
Since river sand can be obtained naturally, it is way cheaper than other types of sand. The presence of silica (below 5%) in them makes them ideal for construction work.
4. M-sand or Artificial Sand

This type of sand is manufactured in factories and is used as a substitute for river sand in the construction of concrete. Ever since the demand for quality grade sand has increased, manufactured sand has been used in construction.
M-sand is manufactured by crushing hard granite rocks which saves the transportation cost involved in bringing river sand from the river banks to the construction site. It contains grains with an angular shape that strengthens the concrete. Angular grains demand water content which is compensated by adding cement to the sand.
Since M-sand is artificially manufactured, it contains no silt or oversized materials typically found in construction materials. It is also free from several impurities and can be control-produced, i.e. The size of the grains can be predetermined to suit individual purposes. The quality can be controlled to provide durability and strength to the concrete. It is quite economical and there will be no defects in construction when M-sand is used.
5. Utility Sand

The type of sand produced from industrial quartz is called utility sand. Utility sand comes with excellent mechanical properties and compaction because of the uniform shape of its grains. It finds its purpose in corrosive environments due to its non-reactive nature. With 100% natural minerals in them, utility sand provides high stability and durability to the structure.
6. Fill Sand

Fill sand, as the name suggests, is used for filling. It is a combination of aggregates (very fine eroded rock particles) and sand grains. Fill sand is primarily used as a base for filling large holes, paving, and laying concrete. It provides excellent compaction and is at an advantage in wet areas (It serves as a backfill around septic tanks).
The Bottom Line: What are Some Other Types of Sand?
Sands are classified based on where they are available, their applications, their properties, and their colour. Apart from the 6 different types of sand mentioned in the article above, there are some other types of sand too. They are
- Gravelly sand
- Coarse sand
- Fine sand
- Plaster sand
- Brick sand
- Sea sand
- Heavy mineral sand
- Volcanic sand, etc.
There are a few deciding factors when choosing the type of sand for construction. The sand should:
- Not contain impurities
- Be free from organic materials
- Contain less than 3% silt
