Background

Since the flexural strength of ordinary concrete is much lower than the compressive strength, the compressive strength is generally the main factor in the mix proportion design. However, in the case of high-performance concrete, since the flexural strength is greatly improved as compared with that of ordinary concrete, the flexural strength is also an important index reflecting the high-performance concrete.

The flexural strength refers to the ultimate breaking stress when the material bears bending moment per unit area, and is also called bending strength and breaking modulus. At present, when a concrete bending test is carried out, two equal loads of an upper pressure head need to be controlled by marking a test piece to simultaneously act on 3 points of the span of the test piece, and the size of a concrete test block is generally as follows: 550 × 150 × 150 or 600 × 150 × 150. In the actual operation process, the scribing needs to spend much time, and meanwhile, because the periphery of the test block is not bound, the test block is easy to shift towards all directions around, so that the whole centering process efficiency of the test is low, and the labor cost is invisibly improved.
