The purpose of mixing the parging concrete is to cover the surface of the aggregates with the cement paste, producing a homogeneous mass. Machine mixing, in the so-called mixers , ensures uniform concretes economically. The mixers are constituted, fundamentally, by a metallic container called drum or vat, provided with pallets in its interior.
Parging concrete mixing is carried out when each part of the concrete is raised, turn by turn, by the paddles during the rotation of the drum, so that at a certain point, in each revolution, they are poured towards the bottom to mix with the other portions, until forming a homogenous mass.
