Flow State, is a mental state where a person is fully immersed in an activity, characterized by intense and energized focus. Often described as effortless effort, when time seems to pass quickly and one is completely absorbed in the present moment. Flow State is associated with peak performance and heightened creativity.

Concrete flow refers to how easily fresh concrete spreads and fills a formwork. It is a measure of concrete’s workability, influenced by factors like water content, aggregate size, and admixtures. Flow tests, like the slump-flow test, help assess this flow and ensure the concrete is suitable for the intended application.
