Introduction

Rebars, or reinforcement bars, are the backbone of concrete structures, providing the tensile strength that concrete lacks. Choosing the right rebars ensures durability, safety, and cost-efficiency in construction. This quiz will test your knowledge of rebars, let’s get started!

 

 

01 /

What is the primary role of rebars in concrete structures?

  • a) To provide compressive strength

  • b) To handle tensile pressure and prevent cracking

  • c) To reduce construction costs

  • d) To replace the need for concrete

02 /

Which type of rebar is highly ductile and commonly used in small-scale residential projects?

  • a) TMT Bars

  • b) Mild Steel Bars (MS Bars)

  • c) Stainless Steel Rebars

  • d) Epoxy-Coated Rebars
