ABSTRACT:
A thin-walled ferrocement product is formed from mortar supplied in a liquid or semi-liquid state, and a thin foraminous layer of reinforcement positioned centrally between the opposite wall surfaces of the product. The liquid or semi-liquid mortar is deposited in a uniform layer on a conveyor and the reinforcing material is positioned parallel to the lower surface of the conveyor. In a preferred embodiment, the material is maintained under tension at the desired position above the conveyor surface as the mortar is deposited onto the conveyor and flows through the foraminous reinforcing layer. The mortar is developed to a coherent plastic state before removal from the conveyor, preferably with the application of heat. The developed plastic material may be formed into various configurations, or may be maintained flat, while subjected to curing to a solid state. The developed plastic ferrocement material may be separated into convenient lengths for handling. The conveyor may be operated continuously or semi-continuously to achieve the desired developing of the mortar. In one preferred embodiment, the conveyor is advanced continuously with the mortar being deposited on the conveyor at one end and being discharged in its developed plastic state at the other end.
