Anti-crack and anti-impact hybrid fiber concrete and preparation method thereof

The invention discloses anti-crack and anti-impact hybrid fiber concrete. The concrete contains hybrid steel fibers formed by steel fibers with different sizes and different shapes; the performance of the concrete is optimized by mixing and doping the steel fibers with different sizes and shapes, and the fibers with different sizes and shapes are mixed and doped into the concrete according to a certain proportion to give full play to the effects of various fibers in different stress periods, so that the expansion of cracks in different stages and different levels is more effectively controlled, and the crack expansion rate is improved. The multi-aspect performance is improved. The typical brittleness characteristic of a concrete material is improved under the condition that the strength of the concrete is slightly influenced, and the toughness, the deformation resistance and the impact resistance of the concrete are greatly improved; the serious safety problem of a concrete structure exposed under the action
