In this research, the things shown below can be done by coating the surface of concrete with metallic layr or ceramic layr.1) To improve the durability2) To prevent from adhesion of aquatic organism3) To be applied as landscape material4) To be used as the material of electromagnetic shielding in refiningThe results corresponding to every heading shown above are summarized as follows.1.The improvement of the durabilityThe exposing test of 8-years in actural environment (the roof of inland areas, the splash zone of share, the tank of excrements disposal), the accelerated exposing test of 2400-hours with weather meter and the freeze & fusion test of 300 cycles were done. According to these results that the filling hollow treatment were done for these sprayd coatings, it has become clear that the durability can be remarkably improved.2.The prevention of adhesion of waterlivesIn the light of the observing result of 10-years in the SAROMA Lake (salt : 3.1-3.3%), it can be said that copper s … More prayd coating and zinc group sprayd coating have bright future in place of antifouling paint of organo tin group in aspect of preventing from adhesion of aquatic organism just as algae, shellfish and ascidium. Because the adherent shellfish was found in the parts of the body of the steel ship in which there were copper sprayd coating and 13% Al-Zn sprayd coating, to counter this, the new experiment has begun on June 1995.3.The application to landscape materialOn the basis of the result observed continuously for 8-years to the accural construction of 30 places, the utility value of the sprayd coating has been affirmed. At the same time, the weather resistance has been confirmed too in accordance with the result of the accelerated exposing test of 300 cycles for 6 kinds of color ceramic sprayd coating.4.The application to electromagnetic shieldingThe electromognetic shielding effectiveness of copper sprayd coating, zinc sprayd coating, carbon steel sprayd coating, felite sprayd coating and metallic foil were measured. According to these results, it has been evendiated that by this method, electromagnetic shielding function can be easily provided to the different kinds of the existing building materials. Less

在本研究中，在混凝土表面涂上金属层或陶瓷层，可以达到以下效果：1）提高耐久性2）防止水生生物附着3）用作景观材料4）在精炼过程中作为电磁屏蔽材料的应用针对以上各方面的研究结果，总结如下：1.耐久性的提高在实际环境中（内陆地区屋顶、犁铧飞溅区、粪便处理池）进行了8年的试验，用气候计进行了2400小时的加速暴露试验，并进行了300次循环的冻融试验。根据这些结果，对这些喷涂涂层进行填充中空处理，可以明显地提高耐久性。2.防止水生物粘附根据在SAROMA湖（盐：3.1-3.3%）中10年的观察结果，可以说铜是一种有效的防腐剂。 ...更多信息 涂料和锌基喷涂涂料在防止藻类、贝类、海鞘等水生生物附着方面具有取代有机锡基防锈漆的良好前景。由于在钢船体上有铜喷涂层和13%铝锌喷涂层的部位发现附着贝类，针对这一情况，于1995年6月开始了新的试验。3.在景观材料上的应用根据对30处建筑物连续8年的观测结果，肯定了喷涂涂料的实用价值。同时，对6种彩色陶瓷喷涂层进行了300次加速暴露试验，验证了其耐候性。4.在电磁屏蔽方面的应用测试了铜喷涂层、锌喷涂层、碳钢喷涂层、金属箔喷涂层的电磁屏蔽效能。根据这些结果，它已被证明，通过这种方法，可以很容易地提供电磁屏蔽功能的不同种类的现有建筑材料。少
