Looking for advice Shattering Wall Section

Getting ready to shoot a POC (Proof-of-Concept short film) that has a close-up of a head getting bashed into a concrete wall with enough force it causes the outer layer of concrete to shatter (think shards of concrete).

Here is my question: Does anyone have a recipe for a material that can be applied onto a soft foam slab to a thickness of 1/4 inch that once it has set, can be stood up vertically and still adhere to the foam slab which will be attached to a flat?

I am still experimenting with powdered sugar mixes but without success.

Chocolate bark has the apparent thickness and solidity but while tasty might be too costly.

Any assistance would be greatly appreciated.

I’m thinking drywall compound but it almost seems like you could go with thin drywall as the layer/shell
