3. Concrete Beam Flexural Test

Flexural test is used to evaluate the tensile strength of the concrete in an indirect way. It tests the capacity of the slab or unreinforced concrete beam to endure bending failure. The outcome of the flexural test on the concrete are demonstrated as a modulus rupture which is signified as (MR) in N/mm2. The flexural test on concrete can be conducted using either three point load test or center point load test. We can determined the flexural strength of specimen of size 150 X 150 X 700 mm, also the specimen of size 100 X 100 X 500 mm can be used if the maximum aggregate size used is not greater than 20mm.
