This study investigated the properties of cement mortar with lime reinforced with plantain pseudostem fibres. Experimental specimens with 0, 0.25, 0.5, 0.75, and 1% fibre contents by weight of sand and 10% lime content by weight of cement were prepared and tested on 7, 14, 21, and 28 days of curing for density, tensile strength, compressive strength, SEM, and EDS. The 0.25% plantain pseudostem fibre reinforced mortar achieved 23.4% compressive strength improvement over unreinforced mortar specimens. There was between 6.89 and 13.80% increase in tensile strength of the plantain pseudostem fibre reinforced mortar over the unreinforced mortar specimens. A positive linear correlation was found between the compressive strength and tensile strength of cement mortar reinforced with plantain pseudostem fibres and lime with coefficient of determinant (R²) values between 0.909 and 0.869. It was also observed that the plantain pseudostem fibre reinforced mortar specimen had some microcracks and voids from the SEM analysis. Furthermore, EDS analysis showed the presence of calcium silicate hydrate with a Ca/Si ratio of between 1.02 and 2.49, and Al/Si ratio of between 0.76 and 0.81 as the main oxide. It therefore concluded that the incorporation of plantain pseudostem fibre and lime positively influenced the properties of the cement mortar with the 0.25% fibre content being recommended for construction application.

车前草假茎纤维和石灰对水泥砂浆性能的影响

本研究研究了用车前草假纤维增强的石灰对水泥砂浆的性能。制备具有0、0.25、0.5、0.75和1％的纤维（以重量计的沙子）和10％的石灰（以水泥的重量计）含量的实验样品，并在7、14、21和28天固化后测试其密度，拉伸强度，抗压强度，SEM和EDS。与未增强的砂浆样品相比，0.25％车前草假茎纤维增强砂浆的抗压强度提高了23.4％。与未增强的砂浆试样相比，车前草假茎纤维增强的砂浆的抗张强度提高了6.89％至13.80％。发现车前草假干纤维增强水泥砂浆的抗压强度与抗拉强度呈正线性关系，决定系数为（R ²）值介于0.909和0.869之间。从SEM分析还可以看出，车前草假茎纤维增强砂浆样品具有一些微裂纹和空隙。此外，EDS分析表明存在作为主要氧化物的水合硅酸钙，Ca / Si比在1.02至2.49之间，而Al / Si比在0.76至0.81之间。因此得出结论，车前草假茎纤维和石灰的掺入对水泥砂浆的性能有积极影响，建议将0.25％的纤维含量用于建筑应用。
