Answer to Question #309389 in Civil and Environmental Engineering for Oxian

Question

What is the purpose of performing the flexure test on concrete? How are the

results of this test related to the compressive strength test results?

Answer 1

 A flexure test produces tensile stress in the convex side of the specimen and compression stress in the concave side. This creates an area of shear stress along the midline. To ensure the primary failure comes from tensile or compression stress the shear stress must be minimized.
