Enhancing the longevity of our built infrastructure will undoubtedly reduce the impact of mankind’s activities on the stability of the biosphere. Attempts to justify fundamental and risky research by promising the solutions of the serious environmental problems faced by society today may sound a bit modish. This, however, should not keep us from starting this research. Not starting this research will worsen the situation. Moreover, a direct benefit for many parties involved in the building industry and for society as a whole is conceivable if it were possible to improvethequality and servicelife ofconcretestructures.Historically,the concrete in these structures has been designed to meet predefined specifications at the start of its life. Longevity of the structure is then monitored through maintenance programs. More recently, however, material scientists have begun to adopt a change in philosophy whereby adaptability or ‘‘self-healing’’ of the material over time is explicitly considered. The inspiration for this change has often come from nature through biomimicry. In concrete, early research in this self-healing area has focusedon boththe natural ability ofhydratestoheal cracks overtime,and artificial means of crack repair from adhesive reservoirs embedded within the matrix. |

延長(zhǎng)建筑物的使用壽命無(wú)疑會(huì)減少人類(lèi)對(duì)生態(tài)環(huán)境穩(wěn)定性的影響。 現(xiàn)在有一種行為非常時(shí)髦,就是努力去證明解決現(xiàn)代社會(huì)面臨嚴(yán)重的環(huán)境問(wèn)題,是十分必要和迫切的。然而,這并不能阻止我們開(kāi)始研究工作。如果不馬上開(kāi)展工作,情況將會(huì)變得更糟。而且如果能增加建筑的質(zhì)量并延長(zhǎng)其使用壽命,對(duì)建筑業(yè)和整個(gè)社會(huì)都是直接有益處的。以前,都是這些建筑在設(shè)計(jì)時(shí)就被預(yù)先設(shè)計(jì)為一定的使用年限,并通過(guò)維護(hù)工作延長(zhǎng)其使用壽命。然而,現(xiàn)在材料科學(xué)提出一種想法,就是希望開(kāi)發(fā)出一種可調(diào)整,或者說(shuō)是“自我修復(fù)”的材料。產(chǎn)生這種想法的靈感來(lái)自于仿生學(xué)。關(guān)于自修復(fù)領(lǐng)域的研究,最早集中于(原文復(fù)制過(guò)程中,有錯(cuò)誤) T In concrete, early research in this self-healing area has focusedon both the natural ability of hydratesto heal cracks overtime,該方法來(lái)與于粘合劑在基體的結(jié)合。 最后兩句不太明白,僅供參考啦。 |

延長(zhǎng)我們的基礎(chǔ)設(shè)施的壽命無(wú)疑會(huì)減少人類(lèi)活動(dòng)對(duì)生物圈的影響。通過(guò)承諾解決一些社會(huì)所面對(duì)的嚴(yán)重的環(huán)境問(wèn)題,來(lái)試圖證明一些基礎(chǔ)性的有風(fēng)險(xiǎn)的科研的正確性,可能聽(tīng)起來(lái)有點(diǎn)追時(shí)髦。然而這不應(yīng)該阻礙我們著手這樣的科研。 不這樣做的話會(huì)讓問(wèn)題更嚴(yán)重。 另外,如果能改進(jìn)混凝土結(jié)構(gòu)的質(zhì)量及其使用壽命, 很多與建筑業(yè)有關(guān)的各方和全社會(huì)都可以看到一個(gè)直接的效益。 歷史上,這些結(jié)構(gòu)中的混凝土設(shè)計(jì)滿足其壽命開(kāi)始時(shí)的預(yù)定要求。 然后,結(jié)構(gòu)的壽命是通過(guò)維修計(jì)劃來(lái)監(jiān)控的。近來(lái),材料科學(xué)家已經(jīng)開(kāi)始接受改變這一理念,即明確考慮材料隨時(shí)間的可適應(yīng)性或者自我修復(fù)。這一改變的靈感常常來(lái)自于自然中的仿生。在混凝土中,早期對(duì)這一自我修復(fù)的研究針對(duì)的即有水合物修復(fù)裂縫的自然能力, 也有通過(guò)嵌入基體的粘合劑儲(chǔ)層人工修復(fù)裂縫的手段。 供參考,不妥見(jiàn)諒 |
