In order to improve the sustainability of cementitious composites used for repair and construction applications, environmentally friendly materials can be incorporated as components in the composites. As materials with a higher ductility are preferred for the repair of structures such as pavement, short fibres can be incorporated into cementitious composites to improve the flexural and tensile strength. In order to develop an eco-friendly composite, this study utilized fly ash to replace a high proportion of Portland cement alongside basalt fibre which is an eco-friendly binder to reinforce to developed composites. Taguchi method was used to design the mixtures in order to investigate the effect of various parameters on the performance of the developed composites. A total of nine mixtures was developed according to the L9 array. Analysis of variance of the experimental results was carried out to evaluate the effect of each of the investigated parameters, and the sum of squares method used to calculate the percentage contribution of each parameter. Results obtained from this study showed that the use of fly ash to Portland cement ratio of 2 to 4 alongside a basalt fibre dosage of 2% resulted in acceptable mechanical properties for repair applications.

为了改善用于维修和建筑应用的水泥复合材料的可持续性，可以将环保材料作为复合材料的成分。由于具有较高延展性的材料是修复诸如路面等结构的首选材料，因此可以将短纤维掺入水泥复合材料中以改善抗弯强度和拉伸强度。为了开发一种环保的复合材料，本研究利用粉煤灰代替玄武岩纤维代替了高比例的波特兰水泥，玄武岩纤维是一种可增强已开发复合材料的环保粘合剂。为了研究各种参数对开发的复合材料性能的影响，使用了Taguchi方法设计混合物。根据L9阵列，总共开发了9种混合物。进行了实验结果的方差分析，以评估每个研究参数的效果，并使用平方和法来计算每个参数的百分比贡献。从这项研究中获得的结果表明，粉煤灰与硅酸盐水泥的比例为2：4，而玄武岩纤维的用量为2％，则可以为维修应用提供可接受的机械性能。
