Using Concrete with Fabrics

We used concrete and I tried to replicate the 'fabric' shape and movement, but the concrete squished the fabric too much, even if I put a material underneath it,

Here are my results with the crystallization of different liquids:

A) B) C) D) E) F) G) H) I) J) K)

Looking at applications with crystallization, I thought of using it in the salt-making industry, to try to extract salt by growing it on the textile.

Another applications is the salt addition to roads with salts, in order to make the ice melt.
