2. Introduction Why we use rebars in concrete structures?
Low tensile strength of unreinforced concrete (results in limited structural
applications)
Bebar’s high strength, ductility, and stiffness impact strength and toughness
to concrete.
3. Objective of the experiment To determine the material properties of reinforcing steel bars
e.g. Elastic Modulus, Yield Strength and Ultimate Strengths
4. Experimental program Specimens
- Three No.5 bars and two No. 2.9 Spirals
Testing Method
- A uniaxial tension test
- using an Universal Testing Machine.
- EA-06-250BG-120 Strain gauges
