Did you know?
WebThe tensile strength of concrete, one of the basic and important properties is which greatly affect the extent and size of cracking in structures. The concrete is very weak due to its brittle nature in tension. Hence the direct tension is not expected to resist. When tensile forces exceed their tensile strength the concrete develops cracks. WebStudies indicate that traditional concrete’s tensile strength varies between 300 and 700 psi, i.e., around 2 to 5 MPa. This means, on average, the tension averages about 10% of …
