What Adheres/sticks To Sand?

[bc55]

Hello,

 

Does anyone know what materials or compounds adhere/stick to sand? For example, like when a magnet that sticks to a fridge.

Cement powder does, although I guess the effect is not magnetic.

Water.

 

The angle of contact between water and silica is very close to zero, indicating a high degree of affinity between water and sand. This is due to the polarity of water and  - more specifically - hydrogen bonding between the oxygen atoms in silica with hydrogen atoms in water.

This would be due to water, dried-on salt or sun cream. By the way, what a lot of bangles she is wearing, esp. for the beach.

All the better to attract barracudas.

There are some sports coatings which are sprayed onto and/or mixed with a sand base. These water based coatings adhere to and bind the sand, into a flexible but tough and abrasive resistant matrix, that can cushion the legs from the impact of sports.
