What happens if concrete slump is too low?
The higher the slump, the more workable or fluid the concrete. Low concrete slump means it’s less fluid and has less workability. If the slump of concrete is too low, it won’t shape very easily. If it’s too high, you run the risk of having the gravel, sand and cement settle out of the mixture, making it unusable.
