<p>At least one strand of fibre is threaded through a flexible hose, the hose is filled with a synthetic resin in fluid form to which an accelerator for the hardening process is added the hose is closed at both ends, and is laid into a mixt. of concrete in a mould, for the prodn. of an armoured casting. Arrangement provides a means of reinforcement using glass fibres which can be applied in a simple and economically profitable manner, for the prodn. of small quantities of castings. The hose is inserted into the wet mixt. in the mould and protects the glass fibres against the alkaline components. The hose and the fibre strand can be prestressed if desired.</p> |
