摘　　要：通过理论分析和实验,研究了锂渣掺量对混凝土性能的影响。结果表明,锂渣能提高混凝土的强度,运用锂渣等量代替一部分水泥(42.5R普通硅酸盐水泥)配制出28d抗压强度为80MPa以上,90d抗压达100MPa以上的高性能混凝土,抗裂能力明显增强,锂渣单掺配制的混凝土能经受300次冻融循环而不破坏。研究的结论提升了锂渣的价值,为锂渣的应用提供有效途径,有助于制备高性能混凝土。The paper studies the influence of lithium slag alone on the concrete performance of by theorial analysis and experimental method. The result shows that replacing a part of cement lithium residue in with concrete can improve the strength of concrete, and can make high-performance concrete whose 28-day compressive strength is more than 80Mpa and 90-day compressive strength is more thanl00Mpa. The capacity of crack resistance is obviously enhanced. It is By the study, which cant be destreied even through at 300 times freeze-thaw recycling. The value of lithium residue, is increased providing helpful to the preparation of high-strength and high performance concrete.
