The invention relates to a composite ceramic fiber used in building concrete and a preparation method thereof. In the invention, the SiO2 sol, the Al2O3 sol and the SiC sol are uniformly mixed to obtain a mixed sol, then the mixed sol is spun to obtain a gel fiber, and the gel fiber is calcined at a high temperature to obtain a composite ceramic fiber. The invention compares the compressive strength of the finished cement mortar mixed with composite ceramic fibers and PP fibers at 3 days, 7 days and 28 days. At 28 days, the compressive strength of the finished cement mortar mixed with composite ceramic fibers is significantly higher than The finished PP fiber cement mortar mixed with it. |
