The concrete was only prestressed to 10 MPa, leading to it becoming susceptible to cracks and water intrusion, which brought about corrosion on the embedded steel.

This compression is made by the tensioning of high-power tendons located within or adjacent on the concrete and is completed to improve the general performance of your concrete in service.[5] Tendons may perhaps consist of solitary wires, multi-wire strands or threaded bars which are most often made from substantial-tensile steels, carbon fiber or aramid fiber.[one]: 52–59  The essence of prestressed concrete is that when the Preliminary compression has long been used, the ensuing content has the properties of superior-power concrete when subject matter to any subsequent compression forces and of ductile higher-power steel when matter to rigidity forces.

In 1079, Bolesław II the Bold entered a conflict Together with the Catholic Church, culminating within the execution of Bishop Stanislaus, which brought about his downfall and exile.[83] After the Loss of life of Bolesław III Wrymouth in 1138, Poland entered a duration of fragmentation, given that the kingdom was divided among his sons into regional duchies.[84] This weakened central authority and created the country liable to exterior threats, like devastating Mongol invasions within the thirteenth century.
