Abstract
Reinforced concrete is a composite material where tensile reinforcement is added to increase its tensile
strength since plain concrete is weak in tension. Reinforced concrete has far more complicated behavior
than plain concrete. This is due to the microstructural changes in concrete as well as the interaction
and link between concrete and steel. Micro-cracking of concrete and steel yielding are the two most
common failure mechanisms in reinforced concrete. Reinforced cement concrete is a durable
construction material, so it is used for decades. Concrete is a composite material; each of these material
has different properties from each other. So knowledge of the properties of concrete, mainly at the
loading stage, is necessary. To remain concrete in good condition, concrete should satisfy the limited
state of serviceability and collapse. Assessing existing structures using non-destructive techniques is a
significant research area in modern engineering due to its ability to estimate structural health without
causing unwanted damage. Among the various established methods, acoustic emission (AE) analysis is
gaining increasing interest in the scientific community. AE can detect the initiation of cracking
processes, identify the types of cracks, and extract additional information from the specimens.
