【導(dǎo)讀】為了拓寬視野,本文對土木工程中的納米技術(shù)的實踐意義和創(chuàng)新作了闡述。納米技術(shù)在構(gòu)建創(chuàng)新基礎(chǔ)設(shè)施系統(tǒng)中。的作用對土木工程的實踐和拓寬領(lǐng)域帶來了革命性的改變。本文首先介紹了納米技。此外,闡述了無論在市場上還是準(zhǔn)備用于建筑行業(yè)的功能導(dǎo)向的納米技術(shù)材料。和產(chǎn)品的細節(jié)以及一定時間內(nèi)可能導(dǎo)致的后果。列舉了一些目前納米技術(shù)在世界各。地不同部分的土木工程領(lǐng)域的應(yīng)用實例。對在最具挑戰(zhàn)性的經(jīng)濟因素下它的實用性。進行了簡要的討論。最后是未來的發(fā)展趨勢,納米技術(shù)的發(fā)展對土木工程向著更經(jīng)。濟的基礎(chǔ)設(shè)施,具有較長使用壽命和低成本的潛在影響的探討。項目業(yè)主的濫用它的功能在慢慢衰退。史上已經(jīng)發(fā)生了很大的變化。粒子的大小是關(guān)鍵因素,在納米技術(shù)中(任何事物,由此納米技術(shù)的研究吸引了大型工業(yè)企業(yè)和風(fēng)險投資家的濃厚興趣和投資。的問題,并可能改變建設(shè)過程中的要求和組織形式。MMFX2鋼的耐腐蝕性與不銹鋼相近,但成本要低得多。

  

【正文】 l production volumes and high cost remain the main barriers to the use of nanotechnology (The Royal Society 2021) 5) The time for mercializing a product is long. . the concrete, which can eliminate the need for reinforcing bars, is projected to be mercialized by approximately 2020. IV. Sustainable Construction At an annual production rate of billion tons, the cement industry contributes about 5% to global anthropogenic CO2emissions. Additives such as belite, calcium 16 sulfoaluminate and calcium aluminoferrite (BASF 2021) have been found to reduce the CO2 emissions by nearly 25% in the production phase A wall made of nanomodified concrete during a cold weather season could potentially be used as a thermal insulator when the outside temperature falls or used as a conductor when the ambient temperature inside the building is low, thereby reducing the energy load required for conditioning the building interior. With further development of LED amp。 OLED technology and progress in the insulating materials and smart glazing, the vision for buildings to meet their own energy requirement will bee a reality. V. Future Projection of Nanotechnology in Construction There is substantial money flowing into nanorelated research from multinational corporations and venture capital investments [3, 5]. Many of the world‘s largest panies such as IBM, Intel, Motorola, Lucent, Boeing, Hitachi, etc. have all had significant Nanorelated research projects going on, or launched their own nanotech initiatives. By 2021, the National Science Foundation estimates that nanotechnology will have a $1 trillion effect on the global economy. To achieve this marketsized prediction, industries will employ nearly two million workers towards advancements in many Nano materials, Nano structures, and Nano systems. The time needed for mercializing a product is long because industries may prefer monitoring development in research agencies and laboratories before making substantial investments. Furthermore, nanotechnology development, particularly in conjunction with biomimetic research will lead to truly revolutionary approaches to design and production of materials and structures with much improved efficiency, sustainability and adaptability to changing environment. VI. Conclusion 17 Research in nanotechnology that is related to construction is still in its infancy。 however, this paper has demonstrated the main benefits and barriers that allow the effect of nanotechnology on construction to be defined. Recent years of Ramp。D have shown massive investments Nanoconstruction. The activities in Nano related products for the construction industry are not well marketed and are difficult for industry experts to identify. A largescale and visible initiative from nanoscience and nanotechnology in the construction area could help seed construction related nanotechnological development. Focused research into the timeous and directed research into nanotechnology for construction infrastructure should be pursued to ensure that the potential benefits of this technology can be harnessed to provide longer life and more economical infrastructure. This paper concludes with a roadmap and strategic action plan on how nanotechnology can have its biggest impact on the field of civil engineering. 18 References [1] Mann, S.
