*3.1.3 Flexural strength*

The flexural strength of brick is its ability to resist bending through internal stresses generated within the brick or flexible pavement. Elastic stresses are developed within the brick and pavement material to resist the external load. Resistant tensile stress that develop, keep the bricks in shape until the failure of the structure. Whenever the material is overloaded the structure will rupture, and flexural cracks are developed at the point of highest tensile stress on the brick or flexible pavement [5]. It's an integral test in determining properties of the brick.
