They are fundamental pieces for the behavior of the reinforcement since they are in charge of transmitting the loads of the beams to the walls or resistant element. They are normally made up of threaded rods and resins, or of mechanical fasteners.
It is the filling element that is responsible for transmitting the loads from the floor slab to the reinforcing beams. The space between the new beam and the damaged beam is filled with mortar with hydraulic binders that do not shrink. Special mortar compatible with aluminous cement is used in the finishing of beams with aluminosis.
