Low-carbon, low-cost, and durable water pipelines are urgently needed for sustainable cities. In this study, low carbon, cost-effective, leakproof Engineered Cementitious Composites (ECC) pipes were developed benefiting from the proposed ECC pipe design model and material innovation. The proposed model has been experimentally validated on ECC beam and ECC pipe. The developed desert sand Engineered Cementitious Composites attained the highest tensile strength (12.6 MPa) and ductility (12.1 %) among the published desert sand ECCs, enabling a sustainable ECC pipe with thinner wall thickness while attaining higher performance. Under the three-edge loading test, the deformation capacity of ECC pipe was 4–6 times that of steel reinforced concrete (RC) pipes. Even with two-thirds the wall thickness of an RC pipe, ECC pipes reached 2.6 times in load capacity of the highest Class V pipes (ASTM C76). The developed ECC pipes hold promise for the next generation of sustainable pipelines.

自下而上的创新,实现可持续防漏工程水泥基复合材料 (ECC) 管道:设计方法、ECC 材料和管道结构
可持续发展的城市迫切需要低碳、低成本和耐用的输水管道。在这项研究中,受益于拟议的 ECC 管道设计模型和材料创新,开发了低碳、经济高效、防漏的工程水泥基复合材料 (ECC) 管道。所提出的模型已在 ECC 梁和 ECC 管上进行了实验验证。在已发布的沙漠砂 ECC 中,开发的沙漠砂工程水泥基复合材料获得了最高的抗拉强度 (12.6 MPa) 和延展性 (12.1 %),使可持续的 ECC 管具有更薄的壁厚,同时获得了更高的性能。在三边加载试验下,ECC 管的变形能力是钢筋混凝土 (RC) 管的 4–6 倍。即使壁厚只有 RC 管的三分之二,ECC 管的负载能力也达到了最高 V 类管 (ASTM C76) 的 2.6 倍。开发的 ECC 管道有望为下一代可持续管道带来希望。
