River Sand as An Important Material for Sustainable Building

River sand is an essential part of construction projects because of the texture, hardness, and size of the material. River sand provides strength to a constructed structure because of its hardness and its composition of exceptionally fine particles.


River sand is gathered from the banks of rivers. However, it can also be produced by a wash plant at a quarry. The material is normally light in colour and consists of particles that are mostly round. It is often used in applications such as plastering. It is, however, essential that the sand be clean and free from clay, debris, organic materials, and stones. The sand can be categorised based on particle size. Exceptionally fine sand consists of particles ranging from 1/16 to 1/8 mm in size, with fine sand ranging in size from 1/8 to 1/4 mm, and medium sand from 1/4 to 1/2 mm. Coarse sand has a diameter range of 1/2 to 2 mm, with very coarse sand being 1 to 2 mm in grain size.

Very fine river sand is best in terms of the sustainability of construction, but the sand grade that you are going to use depends on the particular building application. River sand is widely used in the construction industry for the making of concrete. Sand is also popular for the surface of horse arenas. What makes it well suited for construction projects is the fact that it has been exposed to flowing water and washing for several years. This means it has a low level of silt and clay content. As such, it makes concrete very workable.

It also reduces the water that is required in the concrete mix. The quality of the concrete mix is thus improved, because it does not contain too much clay that can compromise the strength of the concrete structure. When it comes to top-quality river sand, a silt content of less than 3% is required, ensuring the strength and integrity of the concrete mixes. River sand is also an environmentally friendly construction material in the sense that it replenishes itself in nature and it is therefore a sustainable resource.

It can be used with water, gravel, cement, and even steel to create reinforced and thus extremely strong concrete. When used with only water and cement, it is an excellent plastering material. River sand has all the properties needed to make it versatile enough for construction projects ranging from plastering to brick projects, and reinforced concrete.
