River sand is a loose, fragmented natural material that is made up of tiny particles of decomposed shells, corals, or rocks. It is an essential raw material in the construction industry, adding strength and sustainability to buildings. River sand is commonly used in the concrete mix. With a lower clay and silt content in river sand, there is more control over the workability and quality of the concrete and mortar produced. However, the excessive mining of river sand led to environmental degradation.
Read the complete article to learn about river sand and its best alternative.
What is River Sand?
River sand is a natural sand. Unlike other types of sand that are produced by crushing rock, river sand is a naturally occurring sand that is created by weathering or erosion processes. Although the gradation of river sand might vary, it is normally coarse sand. It can be utilized in various landscaping and building tasks, including adding dirt to drainage basins, arena footing, and concrete sand. Since it is formed of the same material as the local rock that it was eroded from, silica sand from quartz is typically the predominant component. Other sources of sand may have rounder shapes, unlike our river sand.
What Are The Properties of River Sand?
1. Workability:
River sand's rounded and smooth granules help to make it workable. Construction materials can be mixed, placed, and finished more easily when they are utilized in mortar and concrete mixtures.
2. Gradation:
The distribution of particle sizes is referred to as river sand's gradation. Better packing and a lower likelihood of segregation in concrete mixes can be achieved using well-graded sand with a balanced particle size distribution.
3. Angular:
River sand has a more rounded shape than crushed or produced sand. The strength of the concrete and its capacity to withstand particular pressures may be affected by its spherical shape.
4. Cohesive and Load-Bearing Capacity:
River sand often has strong cohesiveness and bearing capacity, making it suitable for use in a variety of building applications, such as foundation layers and road construction.
5. Low Permeability:
River sand has low permeability because of its low porosity. This quality can be useful in certain construction and landscaping projects where drainage is crucial.
Advantages of Using River Sand:
1. Widespread Accessibility:
River sand is easily accessible for construction purposes because it is widely available in many areas of the world.
2. Cost-Effectiveness:
Generally speaking, river sand is less expensive than manufactured or sea sand.
3. River Sand Features:
River sand features rounded grains, which improve workability and lower the chance of segregation in concrete mixtures, making it suitable for concrete construction.
4. Natural Composition:
River sand is a naturally occurring product with a combination of different minerals in its composition. These minerals can give construction materials certain advantageous qualities.
Due to its capacity to hold contaminants, river sand is frequently utilized as a filter medium in water treatment procedures and drainage systems.
Disadvantages of Using River Sand:
1. Environmental Impact:
Excessive riverbed sand mining can result in environmental deterioration, which can have an influence on aquatic life, riverbed stability, and the ecosystem as a whole.
2. Non-Renewable Resource:
River sand cannot be replenished, and its overuse could result in its depletion and long-term environmental problems.
3. Impurities:
Salts, silt, clay, organic matter, and other impurities like those found in river sand may alter the qualities of building materials.
4. Inconsistent Quality:
The quality of river sand can differ greatly between locations and even within the same river, which can produce uneven construction outcomes.
5. Environmental Regulations:
Due to environmental concerns, river sand mining is becoming more and more controlled in many locations, making it more challenging to get it legally.
Increased riverbank erosion and sedimentation brought on by excessive sand mining might affect the river's natural flow and result in flooding problems.
6. Alternative Choices are Possible:
Alternative sand sources, including synthetic sand and recycled aggregates, are gaining popularity thanks to technological improvements, which reduce reliance on river sand and address some environmental issues.

Frequently Asked Questions:
Q1. What are some typical applications for river sand?
River sand is frequently used in the construction industry to make plaster, cement, and concrete. Additionally, it is utilized in landscaping initiatives, as paver bedding material, and for various leisure pursuits like beach volleyball courts.
Q2. What is the price of river sand?
Depending on the availability of the river sand, prices for it can range from 1000 ₹ per ton to 3000 ₹ per ton or more.
Q3. Can river sand be used recreationally in place of beach sand?
Even though beach sand and river sand are both naturally occurring sands, their geological origins may cause them to differ in other ways. The texture and color of river sand could be smoother. It is crucial to consider the particular needs of your leisure activity and inquire with local authorities if there are any limitations on utilizing river sand in beach areas.
