Web21 Jul 2024 · The steel reinforcement or tendons (for post-tensioned construction) is an additional important component. The slab is reinforced with steel to prevent flexural failure, and the voids are held in place in the middle of the slab by a cage of thin steel. The concrete that encloses the voids is the third element. WebThe PSC T-Girders steel tub void formers are to be used, producing an open void which facilitates ease of inspection.
