【 摘 要 】

Magnesium phosphate cement prepared by lithium magnesium slag (MKPC) is a re-use of lithium extraction waste, and it is non-toxic. It is a new type of inorganic cementing material with high bonding strength with old concrete, with early strength and fast hard characteristics, which can meet the requirements of rapid repair. In this research, the effect of using magnesium phosphate cement on the strengthening of concrete bonded with different fiber cloths was studied. The experimental results showed that the effect of using magnesium phosphate cement on the strengthening of concrete bonded with carbon fiber cloth was obvious. But, the effect of reinforcing the glass fiber cloth on the plain concrete is not obvious.
