The grains size and shape (morphology) of sand is a very important physical property in evaluating sand for different uses. So, what are the sand applications based on the two preceding properties?
The size and shape (morphology) of sand grains play a crucial role in determining the suitability of sand for different applications. Here are some examples of sand applications based on these physical properties:
Construction: Sand with a consistent grain size and rounded shape is ideal for construction applications such as concrete production and masonry. The rounded shape of the grains improves the flowability and workability of the concrete, and the uniform grain size ensures a consistent strength and finish.
Filtering: Sand with a consistent grain size and angular shape is ideal for filtering applications such as water treatment and oil and gas production. The angular shape of the grains provides a larger surface area for the fluid to filter through, and the uniform grain size ensures efficient filtration.
Beach nourishment: Sand with a consistent grain size and rounded shape is ideal for beach nourishment. The rounded shape of the grains makes it less likely to be transported by wave action, and the uniform grain size ensures a consistent beach profile.
Fracking: Sand with a consistent grain size and angular shape is ideal for hydraulic fracturing (fracking) in the oil and gas industry. The angular shape of the grains provides a better proppant to hold open the fractures created in rock formations.
Sand blasting: Sand with a consistent grain size and angular shape is ideal for sand blasting applications. The angular shape of the grains provides a better abrasive effect than rounded grains.
Sand filling: Sand with consistent grain size and angular shape is ideal for filling applications such as landfills, trenches and foundations. The angular shape of the grains provides a better stability and support.
In summary, the applications of sand depend on the size and shape of the grains. Sand with consistent grain size and rounded shape is ideal for construction, beach nourishment, and others. Sand with consistent grain size and angular shape is ideal for filtering, fracking, sand blasting, and sand filling.
