摘要:
滨海地区排水管道长期服役于高盐、高湿度环境，传统混凝土及钢筋混凝土管材易腐蚀劣化，影响系统运行安全。为提升排水管道耐久性，采用工程水泥基复合材料（ECC）制备管材，并开展海水环境下的抗压、拉伸及外压荷载试验。结果表明，ECC管经270 d海水浸泡后，抗压强度提升至56.1 MPa，极限抗拉强度达4.70 MPa，仍保持0.8%的延性，外压承载力优于现行Ⅲ级钢筋混凝土管标准要求。ECC管无需配置钢筋即可实现良好的抗裂和承载性能，在高腐蚀、高湿度环境下表现出优异的耐久性与工程适配性。
Abstract:
In coastal areas, drainage pipes are exposed to high-salinity and high-humidity environments for extended periods, where traditional concrete and reinforced concrete pipes are prone to corrosion and deterioration, compromising system safety. To enhance the durability of drainage pipes, this study utilized engineered cementitious composites (ECC) to fabricate drainage pipes and conducted compressive, tensile, and external load-bearing tests under simulated seawater conditions. The results show that after 270 days of seawater immersion, ECC pipes achieved a compressive strength of 56.1 MPa, an ultimate tensile strength of 4.70 MPa, and maintained a ductility of 0.8%. The external load-bearing capacity exceeded the standard requirements of class Ⅲ reinforced concrete pipes. Without requiring steel reinforcement, ECC pipes demonstrated excellent cracking resistance and load-bearing performance, along with outstanding durability and engineering adaptability in severely corrosive and high-humidity environments.
