Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4â) slump is very common with normal weight concrete and is a good average slump for pumping. Above average slump - due to the addition of water â considerably reduces the strength, durability, and permeability of concrete and can cause segregation.
