How do concrete pumps work?
I really wonder how concrete pumps work, liquid (fluid) concrete has a big viscosity, how the pump overcome this big viscosity. I witnessed many times every couple seconds maybe 4-5 seconds the machine emits a loud thump. I think that sound come from pnomatic part of the machine. If anyone know how is it working, I will be glad to hear it, I wish Merry Christmas to all.
In addition to water and cement, concrete usually has a mixture of other substances added for strength. The most basic concrete has aggregates made up of a mix of sizes of gravel and sand. Other additives are sometimes used to change characteristics of the concrete including: the speed at which the concrete sets, how well the mixture flows, the strength of the set concrete and its colour.
Concrete is formed by a chemical reaction called hydration between water and cement. The cement is usually a compound called Portland cement.
Concrete is very strong under compression, and often incorporates steel or other materials, as either a grid cast within it or as fibres added to the mixture, that give the final concrete more strength under tension. A concrete is a mixture of cement, fine aggregate, coarse aggregate, et de l'eau. In some cases concrete admixtures are added to improve the properties of the concrete.
