Cast building product production from sprayed sand and clay mixture includes subjecting it to high pressure, then accelerating it through nozzle and flight path onto target

摘要

A homogenous mixture is prepared from sand and clay concentrate, the sand being saturated with water or a dry concentrate. The mixture is fed continuously or in batches to a unit for high pressure acceleration through a nozzle. A target is positioned at the end of a free flight path. This is an impact plate, grid, surface or mold of adequate strength. Acceleration and impact promote high pressures against the target area. Intimate internal bonding and dimensional stability result from step-by-step formation.
