Answer 2

(D) 28 mm

Explanation:

• Concrete reinforcement bars ensure that a structure's integrity is consistent.
• Although concrete is robust in compression, it has essentially little tensile strength, which means it will ultimately fracture and bend.
• To ensure safe building methods, it's necessary to choose the proper rebar weight and size.
• 16mm, 20mm and 25mm size bars are denoted as T16, T20 AND T25 respectively.
• The mass Kg per metre of steel bars T16, T20 AND T25 are 1.579, 2.466 and 3.854 respectively.
• Because of their great corrosion resistance, stainless steel rebars are the ideal option when it comes to reinforcing bars. Stainless steel rebar increases the tensile strength of concrete, making it more resistant to cracking and failure.
