How Many Types of Construction Sand Are There, and How Are They Used in Construction?

**Construction sand** is one of the key raw materials used in structural and finishing work—concrete mixing, masonry, plastering, and site preparation.

**Types of Construction Sand**

1. **Fine Sand** – small grain size

   – Wall plastering, finishing, masonry

   – Helps construction surfaces be smooth

2. **Coarse Sand** – larger grain size

   – Concrete mixing, floor pouring, structural work

   – Increases concrete strength

3. **River Sand** – from natural sources

   – Round grains, highly clean

   – Used in various types of construction

4. **Upland Sand** – from land sources

   – Coarser grains, may have more contaminants

   – Usually requires sorting before use

**Choosing Sand for Construction**

– Plastering: Fine sand

– Masonry: Fine or medium sand

– Concrete: Coarse sand

**Standards**

– FM (Fineness Modulus) value

– Sand cleanliness

– Contamination level
