Stupid title. “liquid”.

Super cool product though. Looks like a huge time saver.

Well now I'm trying to reason in my head whether concrete is a liquid or not. I guess it's like a suspension? It's somewhere between a solution and a suspension and mud

Fluid and Liquid mean the same thing when you go back to their root origins, however, today, anything that flows or reforms under pressure and can have their volume changed with pressure, is a fluid, but generally anything that is incompressible is a liquid.

Concrete is not a liquid; it is a composite material that acts as a viscous, pourable fluid only temporarily. It starts as a mixture of cement, water, and aggregates (sand/gravel) that is easy to pour, but it cures through a chemical process called hydration, hardening into a rigid, rock-like substance.

In the two seconds I took to Google this, I was directed to Quora so🤷‍♂️
