摘要
随着国家蓝色海洋战略的推进,混凝土在各项海洋工程设施(跨海大桥、海底隧道、海港码头等)中得到了广泛应用。混凝土在服役期间会受到物理、化学以及生物作用的协同破坏,最终导致其劣化,其中物理和化学作用导致混凝土劣化的机理已研究的比较详尽,然而在海洋环境中生物作用所引发的混凝土劣化,尤其是宏观生物(植物型和动物型)对混凝土的劣化作用鲜有研究人员探讨。因此,对海工混凝土宏观生物的腐蚀机理、影响宏观生物附着行为的因素以及防护措施等方面进行综述。以期得到国内外专家学者的关注,寻求一种更加合理、高效、经济且环保的海工混凝土腐蚀治理措施。
With the promotion of the national blue ocean strategy,concrete is widely used in various marine engineering facilities(i.e.,cross-sea bridges,sub-sea tunnels,harbour terminals,etc.).However,concrete suffers from physical,chemical and biological synergistic effects during its service,eventually leading to its deterioration.The mechanism of concrete deterioration caused by physical and chemical effects is well known.In the marine environment,however,the mechanism of concrete deterioration caused by organisms,especially macro organisms(i.e.,plant type and animal type)is still unclear.Therefore,this review represented recent work on the corrosion mechanism of macroscopic organisms in marine concrete,some factors affecting the attachment behavior of macroscopic organisms,and the related protective characterizations as well for more reasonable,efficient,economic and environmentally friendly corrosion management of marine concrete used.
