Abstract
From the beginning of its construction to the present, concrete has played a huge role in architecture. The mechanical properties of concrete, such as compressive strength, elastic modulus, and different tensile strength (flexural strength, inherent tensile strength, and tensile strength per unit), are important aspects when calculating and determining the size of concrete structures. Compressive strength and tensile strength are important parameters to measure the quality of concrete structures. The design criteria of concrete structures depend on the compressive strength of concrete in most cases. It is not designed for direct loading. Tensile strength should be considered because it has a significant effect on stress cracking. In addition, the tensile strength of concrete needs to be determined.
