A concrete beam can carry a substantial load before its first major crack, then lose capacity quickly. For a floor, overlay, precast unit, or repair layer, the load after cracking can matter as much as the first peak. Flexural toughness describes how the material continues to resist bending and absorb energy as it deforms.
