Workability And Proportion Design Of Pumping Concrete

Workability and proportion design of pumping concrete

Jul 01, 2013 Compared to the traditional way for concrete construction, the concrete is pumped through a pipe by concrete pumping truck the properties and proportions of pumping concrete are quite different from that of traditional concrete. The feasibility that concrete could can be pumped is defined as workability, also called pumpability or flowability.

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 4 slump is very common with normal weight concrete and is a good average slump for pumping.
