In more practical terms, creep is the increased strain or deformation of a structural element under a constant load. Depending on the construction material, structural design, and service conditions
Batching of lightweight concretes is normally done from ready-mixed concrete producers. At low workabilities, the concrete can easily be placed by skip or chute. Pumping lightweight concrete can be achieved, but care needs to be taken so that the concrete mix doesn't separate.
1/4/2001 · In the United States, most ready-mixed concrete is mixed in trucks  and not pre-mixed in a plant. In a tilting drum mixer ( Fig. 3 ), the inclination can be varied. When the drum is almost horizontal (inclination ≈ 0°), more energy is provided to the concrete because more concrete is lifted to the full diameter of the drum before dropping.
