Low rates of air entrainment promote column collapse by inhibiting jet buoyancy. The seed entrainers receive seed from the one or more hoppers. Air entrainment occurs as a result of a tape floating force, which increases with tape travel speed, suggesting a mechanism similar to an active pressure air bearing. It is achieved by adding a surface active agent in very small dosages to the concrete mixture.
