Abstract

A structured approach to optimising the constituents of engineered cementitious composites (ECC) is crucial for reducing resource intensity and improving design efficiency. This study presents the design of a novel sustainable ECC that simultaneously achieves high strength and ductility, incorporating hybrid fibres, nanocellulose (NC), and high volumes of fly ash and silica fume. A novel approach utilising the hybrid application of Taguchi- Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods is adopted for the design, enabling systematic and precise adjustment of mix constituents and leading to optimized performance. The standard Taguchi orthogonal array, consisting of four factors, i.e. fly ash to silica fume ratio, water-to-binder ratio, fibre proportions, and nanocellulose dosage, was used to design the mix. The optimum combination of these constituents was determined to maximize five key response parameters: compressive strength, elastic modulus, flexural strength, tensile strength, and ultimate tensile strain. Results indicated that fly ash to silica fume ratio of 1:0.2, a water to binder ratio of 0.22, 1.5 % polyethylene +0.75 % steel fibre by volume, and 0.25 % NC by weight represent the optimal mix design. This mix achieved a compressive strength of 71 MPa, an elastic modulus of 30 GPa, a flexural strength of 17 MPa, an ultimate tensile strength of 4 MPa, and an ultimate tensile strain of 3 %. The optimal design was further validated by experimental results, which showed that the optimized mix outperformed all other mixes in all indices. This further demonstrates the effectiveness of the design method and the potential for successfully incorporating nanocellulose in ECC designs.
使用田口topsis分析优化混杂纤维和纳米纤维素增强工程胶凝复合材料
优化工程胶凝复合材料(ECC)成分的结构化方法对于降低资源强度和提高设计效率至关重要。本研究提出了一种新型可持续ECC的设计,同时实现了高强度和延展性,结合了混合纤维,纳米纤维素(NC),以及大量的粉煤灰和硅灰。设计采用了一种新的方法,利用田口技术的混合应用,通过与理想溶液相似的偏好顺序(TOPSIS)方法,实现了混合成分的系统和精确调整,从而优化了性能。采用标准田口正交法,由粉煤灰硅灰比、水胶比、纤维比和纳米纤维素投加量4个因素组成。确定了这些成分的最佳组合以最大化五个关键响应参数:抗压强度,弹性模量,弯曲强度,拉伸强度和极限拉伸应变。结果表明,粉煤灰与硅灰比为1:0.2,水胶比为0.22,聚乙烯体积比为1.5% +钢纤维体积比为0.75%,NC重量比为0.25%为最佳配合比。该混合物的抗压强度为71 MPa,弹性模量为30 GPa,弯曲强度为17 MPa,极限拉伸强度为4 MPa,极限拉伸应变为3%。实验结果进一步验证了优化设计,优化后的混合料在各项指标上均优于其他混合料。这进一步证明了设计方法的有效性,以及在ECC设计中成功结合纳米纤维素的潜力。
