With the increase of PVA fiber content, the bending strength of magnesite plate increases obviously, which indicates that the bridge effect between PVA fibers is more and more obvious. However, when the content of PVA fiber continues to increase, the increase of bending strength of the sample slows down. It is considered that more PVA fibers are not easy to disperse in the slurry, which makes the structure of the sample uneven, so the increase of strength slows down. It is considered that th
