迄今为止,在海水中建造防波堤、防水堤、水下桩和其他设施所用的材料,仍然和在陆地上使用的建筑材料相同。这样,由于海水的腐蚀作用,就需要定期对它们进行检修,其费用是很大的。众所周知,海水中含有钙、镁和碳酸盐。海洋生物广泛和有效地利用它们得到了机械性能牢固、保存时间长久的结构,如蚌壳和珊瑚碓。因此,为得到比钢和混凝土更适合在海水中使用的物质,直接利用大自然是十分有意义的。澳大利亚昆士兰州汤斯维尔市的约翰·库克大学,研究出了一种用海水生产直接粘附在
To date, the materials used to construct breakwaters, waterproof embankments, submerged piles and other facilities in seawater are still the same as those used on land. In this way, due to the corrosive effects of seawater, they need to be regularly overhauled, and the cost is very large. As we all know, seawater contains calcium, magnesium and carbonate. Marine organisms use them extensively and effectively to obtain structures with strong mechanical properties and long-term preservation, such as clam shells and coral reefs. Therefore, in order to obtain a material that is more suitable for use in seawater than steel and concrete, direct use of nature is of great significance. John Cook University in Townsville, Queensland, Australia developed a method for direct adhesion to seawater
