摘　　要：运用正交试验设计的方法配制锂渣复合粉煤灰高性能混凝土,运用极差分析和方差分析的方法分析了水胶比、锂渣掺量和粉煤灰掺量对锂渣复合粉煤灰高性能混凝土的早期抗压强度的影响,得出锂渣较粉煤灰对锂渣复合粉煤灰高性能混凝土早期抗压强度影响显著。在进行极差分析时,引入了极差相对差异度这一概念。Lithium slag compound fly ash high performance concrete was made by the orthogonal experiment design method,the preparation of the use of poor analysis and variance analysis method to analyze the impact that the water-binder ratio,lithium slag mix content and the fly ash for lithium slag compound fly ash of high performance concrete compressive strength of the early.Lithium slag on lithium slag compound fly ash high performance concrete compressive strength has significance effects Dmng early.Dmng analysis of the poor,poor relative difference degree was introduced the concept.

关 键 词：正交设计试验 早期强度 极差相对差异度
