Silica Sand (balangankab.go.id)

YOGYAKARTA - What is silica sand can be understood as one of the materials that have many uses in industry. This mineral has several mentions, namely quartz sand or silica sand. The importance of the function of silica sand makes Indonesia quite attractive as one of the countries with the largest amount of reserves. Even Indonesia is one of the countries that export quartz sand. In this article, the meaning of silica sand will be discussed until its benefits.

What is Silica Sand

Simply put, silica sand is one of the natural minerals consisting of small particles containing silicon dioxide (SiO2). In Indonesia, this material is actually found a lot on the beach or in the river.

In a scientific article entitled Identification and Characterization of Silica Sand Minerals as Potential Material for Majudi Padang Garugur River, North Sumatra, Emi Rahwani Siregar, et al. (Hadron Journal of Physics and Applied: 2025) explained that silica sand has a variety of colors, such as clear white, gray, yellow, red, or brown.

Silica sand does not appear out of thin air. The mineral is formed from the weathering of rocks that are then carried away by water or wind and then settle in the open air. Silica sand deposits can be found in rivers, lakes, or seas.

Function of Silica Sand

Silica sand minerals have been used in the industrial world to become useful products. The following are some functions of silica sand in the industrial world.

Glass raw materials

Did you know, silica sand is the basic material for making glass ranging from furniture glass, bottles, optics, fiberglass, even glass on optical fibers. This sand is able to produce transparent glass as well as heat resistant.

Used in the construction industry

In the construction world, silica sand is used as a mixture in concrete, mortar, special cement, plaster, asphalt, and aerated lightweight bricks. The mixing is done to add structural strength, stability, corrosion resistance, and much more.

To clarify the water

Silica sand is also often used to help clear water. This mineral is able to be a filter medium to filter out dirt, suspended particles (TSS), mud, and other contaminants in water. By using silica as a filter, the filtered water can be much clearer.

As a sports ground

In the world of sports, silica sand is often used as infill in golf courses, bunkers, synthetic grass, futsal courts, or other sports arenas. This sand is also used as stability of the ground surface of sports fields.

Sand blasting

Silica sand can also be used as an abrasive to clean the metal surface from rust, old paint, or corrosion before being coated again. For this function, the sand used is a mesh size of 14-30. This use is carried out by silica sand having a high hardness level with a sharp angle so that it is effective for cutting the surface without damaging the substrate.
