Answer / v.somesh

Concrete's best strength rating is in compression, as in equal force from either side. Its weakest rating is in its shear strength, as in force in different areas like snapping a pencil in your hands. To increase concretes shear strength, re-inforcing steel bar is used because of its high shear strength characteristics.
