Hi Samson. Thank you for your question.

River sand particles are round and smooth, which is one of the most popular aggregates in infrastructure projects. Since sea sand contains a large amount of chloride ions, it easily corrodes the steel bars in reinforced concrete, so its use is restricted. The following mainly tells you some simple methods to distinguish between sea sand and river sand.

First of all, from the appearance, the sea sand particles are large, containing many shell fragments, so it feels rough in the hand. The real river sand is uniform and delicate, which contains pebbles of different sizes, and the density between the gravels is high; In addition, you can pay attention to the sticky feel, grasp some sand in your hand, and then take it off. It is found that the sticky hand is sea sand, and the non-stick hand is basically river sand;

Secondly, From the color point of view, the sea sand is slightly black and dark brown, and the river sand is relatively yellow and bright;

Finally, under of the sun, white sand precipitated is the sea sand.

It is worth noting that the use of sea sand is explicitly prohibited in some areas, but as river sand becomes a scarce resource, how to use sea sand needs to be discussed again. I believe that after the technology is mature, sea sand can also be used reasonably.
