Yes, river sand can be used to build.
River Sand in Construction
Based on the reference provided, river sand is widely used in construction activities. Its suitability stems from its inherent properties shaped by natural processes.
Properties and Uses
Due to its natural weathering, river sand possesses rounder grains compared to other types of sand. This characteristic makes it suitable for specific applications in building. According to the reference, it is primarily used as a fine aggregate in the production of:
- Concrete: A fundamental building material used for foundations, slabs, walls, and structural elements. Sand provides volume, stability, and workability to the mix.
- Mortar: Used to bind bricks, blocks, or stones together in masonry construction. Sand provides body to the mortar, prevents excessive shrinkage, and helps achieve the desired consistency.
These applications demonstrate that river sand is indeed a valuable component in various construction processes.
Why River Sand is Chosen
The roundness of river sand grains, as mentioned in the reference, contributes to better workability and flow in concrete and mortar mixes. This makes the mixing process easier and helps achieve a denser, more uniform final product when properly mixed with other aggregates and binders.
While river sand is widely used, its suitability can depend on factors like cleanliness (absence of silt and organic impurities) and gradation (particle size distribution). However, when sourced and processed correctly, it is a standard and effective material for building projects.
