ABSTRACT:
The invention provides a process for producing fabric-reinforced, thin concrete panels suitable as a backer board for construction materials such as ceramic tile, slate or thin brick. A process is described whereby the components of the panel are deposited on a web of release-agent-treated, water-absorbent paper while moving on a conveyor belt to form a continuous strip, the strip is cut into panels and the wet, uncured panels are stacked by means of an air-float stacking unit, then subsequently cured with the paper web between adjacent panels.
