The bond between the concrete and the prestressed tendons is crucial in the process. Due to the high forces involved, prestressing is a potentially dangerous operation, requiring strict health and safety procedures. It also requires specialist hydraulic equipment, either for single strand or multi-stressing. Hollowcore Machinery.
