Abstract: The present invention relates to continuous concrete casting by extrusion and, in particular discloses the process, method and apparatus by which substantially continuous lengths of cast reinforced or prestressed concrete products or other composite products from different materials can be extruded. Pressure used in the extrusion process can lead to beneficial effects arising from faster setting and concrete hardening under high pressure, mix dewatering in porous mould surfaces and the introduction of reinforcement. Judicious combinations of surface lubrication with driving pressures can lead to longitudinal prestressing of reinforcement. Multi-layered composite products can also be extruded. Products may be flat or have single or double curvature in axi-symmetric three dimensional shapes, as well as other more complex three dimensional shapes such as the helix. The output from the process may be either continuous or discrete elements.

Abstract: A flexible formwork assembly (11) into which concrete is delivered to form a concrete structure (10). The formwork assembly (11) includes flexible sheets (12, 13) suspended from a support assembly (18). The sheets (12, 13) surround a reinforcing cage (15). Fixed to the exterior of the sheets (12, 13) are stress distribution members (16), which stress distribution members (16) are arranged in pairs with the ties (17) extending therebetween. If so required, the reinforcing cage (15) can be used as the main frame or skeleton to hold and support the sheets (12, 13). Spacers (145) can be used to aid in maintaining the sheets (12, 13) in a desired position prior to pouring of the concrete. The formwork assembly (10) can be supported on the reinforcing cage (15) so that the formwork (10) follows the general configuration defined by the reinforcing cage (15). In situ concreting of walls of most shapes and configurations under water is possible.
