We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

You need to know the tensile strength because a bending test creates tensile stress on one side of the joint and compressive stress on the opposite side of the joint.  This is important because the tensile strength is much lower than the compressive strength for concrete.

Do you have a different strength for the joint material and the concrete block material, or are they the same?

If the strengths and properties of the two materials are the same, the adhesion is perfect and the joint covers the entire area of the ends of the blocks, that seems equivalent to having no joint. Instead of analyzing two 50 cm long blocks that are joined, you can just analyze one 100 cm long block of concrete.
