摘 要：聚合物改性水泥砂漿綜合力學性能指標相比傳統(tǒng)壓折比可更加全面地反映復合材料改性后強度和韌性的改善。通過正交試驗研究聚合物改性水泥砂漿的綜合力學性能指標。考察水膠比 、聚膠比 、砂膠比及水泥礦硅比四個因素，采用 L16 (45 ) 正交進行試驗。結(jié)果顯示：極差分析和方差分析結(jié)果表明各因素對聚合物改 性水泥砂漿綜合力學性能指標的影響顯著程度次序不盡相同，且無重復試驗方差分析所對應因素顯著程度低于重復試驗；重復試驗的方差分析表明，砂膠比和聚膠比是綜合力學性能指標的顯著影響因素。

關鍵詞： 聚合物改性水泥砂漿；綜合力學性能指標；壓折比；正交試驗；因素水平；影響顯著程度

Abstract : Compared with the traditional index (compressive to flexural ratio) , comprehensive mechanical performance index (CMPI) is more comprehensive response the strength and toughness improvements of modified composite material. CMPI of polymer modified cement mortar ware studied based on the orthogonal experiment. Four factors as water - binder ratio , polymer - binder ratio , sand - binder ratio , cement - slag and silica afume ratio , and each factor had four level values. The experimental results ware conducted and studied according to the orthogonal table L16 (45 ) . The results of variance analysis and range analysis show that the significant effect degree of the four factors on the CMPI was not the same , and the significant effect degree concluded from the variance analysis of repeated test data was larger , compared with the separate tests. The variance analysis of repeated test shows that sand - binder ratio and polymer - binder ratio had a significant effect on the CMPI of polymer modified cement mortar.

Keywords : polymer modified cement mortar; comprehensive mechanical performance index (CMPI) ; compressive to flexuralratio; orthogonal experiment; factor level; the degree of influence
