The result shows that replacing a part of cement lithium residue in with concrete can improve the strength of concrete and can make high-perform- ance concrete whose28-day pressive strength is more than80 Mpe and9O-day pressive s trength is more thanl(0Mpa.The capacity of eruck resistanee is obviously enhanced.It is By the study which cant be destroied even through at 300 times freeze-thaw reeyeling.The value of lithium residue is increased providing helpful to the preparation of high-strength and high performance conerete...
