采用正交的试验方法，以混凝土强度3，7，28，90 d龄期的抗压强度和28 d龄期的劈裂抗拉强度作为评价指标。试验结果表明水胶比以0．27为最优，以28 d龄期为准，由试验确定的最佳锂渣和钢渣掺量分别为10％和20％，锂渣、钢渣高性能混凝土28 d劈裂抗拉强度在一定程度上与其抗压强度呈现比例关系。在最优水胶比条件下，锂渣、钢渣高性能混凝土的28 d龄期及28 d龄期以后的抗压强度均高于常规混凝土和单掺锂渣混凝土，同时，7～28 d龄期的锂渣、钢渣混凝土强度增长幅度最大且最优。
採用正交的試驗方法，以混凝土彊度3，7，28，90 d齡期的抗壓彊度和28 d齡期的劈裂抗拉彊度作為評價指標。試驗結果錶明水膠比以0．27為最優，以28 d齡期為準，由試驗確定的最佳鋰渣和鋼渣摻量分彆為10％和20％，鋰渣、鋼渣高性能混凝土28 d劈裂抗拉彊度在一定程度上與其抗壓彊度呈現比例關繫。在最優水膠比條件下，鋰渣、鋼渣高性能混凝土的28 d齡期及28 d齡期以後的抗壓彊度均高于常規混凝土和單摻鋰渣混凝土，同時，7～28 d齡期的鋰渣、鋼渣混凝土彊度增長幅度最大且最優。

The paper used orthogonal test method and took concrete compressive strength of 3 , 7 , 28 , 90 days and splitting tensile strength of 28 days as the evaluation index .The experiment results show that the optimal water cement ratio of concrete is 0.27.Taking the concrete compressive strenght of 28d as the standard , the mixing amount of lithium slag ash and steel slag determined by test are 10% and 20%. The splitting tensile strength of 28 days of HPC added with lithium slag and steel slag presents positive re-lation with compressive strength of that .Under optimal condition of water-cement ratio , the compressive strength of 28 days or after 28 days of HPC added with lithium slag and steel slag are higher than that of ordinary concrete and single doped lithium slag concrete .While the increase of strength of HPC added with lithium slag and steel slag in 7 to 28 days is the biggest and optimum .
