CIP 16 - Flexural Strength Concrete
www.crmca.comCIP 16 - Flexural Strength Concrete WHAT is Flexural Strength? Flexural strength is one measure of the tensile strength of concrete. It is a measure of an unreinforced con-crete beam or slab to resist failure in bending. It is measured by loading 6 x 6-inch (150 x 150-mm) con-crete beams with a span length at least three times the depth.
