Concrete for pumping

Concrete for pumping. The concrete mix design must be correctly proportioned so that the concrete will flow easily and uniformly through the pipe-line. The pipe diameter should be 3.5 to 4 times greater than the maximum aggregate size in the concrete. This helps ensure that the pipeline will not become blocked.

Best Mix for Pumped Concrete | JLC Online

1/3/2010 · The ideal concrete mix for pumping typically contains air-entraining agents, a little extra sand (compared with a standard concrete mix), often some fly ash, and a well-graded aggregate blend. To make the concrete easier to pump and place as it comes out of the hose, many batch plants also add water-reducing admixtures — known as superplasticizers — to their concrete.

1/1/1976 · The Mix Design 283 Thus a high consistency (high slump) concrete has a low plastic viscosity whereas a low consistency (low slump) concrete has a higher viscosity. The viscosity, however, gives no information about the ability of the concrete to withstand pressure gradients and, at this point in time, a laboratory type test which measures this property under variable pressures would be valuable.
