by Concrete, as a heterogeneous, multiphase, and multi-level composite system, has an extremely complex micro pore structure with diverse pore shapes and a significantly wider range of pore size distribution compared to other porous materials.
At present, fiber-reinforced concrete, as an important means of concrete modification research, has achieved good substantive results.
Therefore, fiber-reinforced concrete has become a new type of composite material.
Fiber reinforced concrete can leverage the performance advantages of fibers in concrete, reducing inherent defects, optimizing pore structure, and improving corresponding mechanical strength.
On the other hand, it can also increase the internal interface of concrete, and concrete requires more time for mixing, which may introduce more bubbles and have adverse effects on the pore structure.
