Using small charges, they were able to create a cement-like bond between grains of sand.
Rotta Loria decided to a different energy source, in the form of electric shocks.
The latter is the primary material found in mollusk shells, while the former is common in many stones.

After being treated, the sand looks like a rock, Rotta Loria said.
It is still and solid, instead of granular and incohesive.
The applications of this approach are countless, he said.
We could also use it to strengthen protection structures, marine foundations and so many other things.
There are many ways to apply this to protect coastal areas.
