With the development of the technology and the production,more and more high performance concrete(HPC)and high performance mortar(HPM)are needed.In order to get all kinds of high performance concrete and high performance mortar,a lot of researches have been done.For example,many researchers used the methods of magnetized water and electricalwater to improve the mechanical performance of the mortar. With these methods,the strengthening effect is not so good,and the value is fluctuated.They are not accepted extensively because of that.However,a method called electro_hydraulic impulse method is described in this paper.With this method,the mechanical performance of the mortar is increased by 20%.It must be pinted out that different results are gotten when different parameters are chosen.Because of the limited experimental conditions,the most optimized parameters haven't been found.So it can be sure that some better results can be gotten with the most optimized parameters.Comparing with other methods,the method of electro hydraulic impulse is more simple,more useful.
