Yes, steel rebars can be used in pre-stressed or post-tensioned concrete structures. In pre-stressed concrete, the rebars are tensioned before the concrete is poured, creating compression within the concrete to counteract external loads. In post-tensioned concrete, the rebars are tensioned after the concrete has set, providing additional strength and reducing cracking. Steel rebars are commonly used in both types of structures due to their high tensile strength and ability to withstand the stress induced by the pre-stressing or post-tensioning process.
Yes, steel rebars can be used in both pre-stressed and post-tensioned concrete structures. In pre-stressed concrete, the rebars are tensioned before the concrete is poured, while in post-tensioned concrete, the rebars are tensioned after the concrete has hardened. The tensioned rebars help to improve the strength and durability of the concrete structures.
