项目摘要
* **Smart cities are cities that integrate infrastructure*and services to produce an efficient urban eco-system that integrates institutional,*physical, social and economic infrastructure through smart sensors and advanced*data-science. Concrete infrastructure in a Smart City must not only be safe and*sustainable, but must also integrate Internet of Things (IoT) and Information*and Communication Technology (ICT) to achieve operational efficiency,*cost-effective maintenance and end-of-life deconstructability. The primary*objective of this proposal is to contribute towards development of safe, sustainable,*and digitally-monitored concrete structures for Smart Cities. These objectives apply not only to new*construction, but also to deteriorated structure that need to regain their lost*capacity, as well as structures that are not deteriorated but still requires*strengthening against calamities such as earthquakes and fires. *** ***This proposal focuses on development of highly*damage-tolerant materials that utilize principles of nanotechnology to depict self-healing,*smartness and low-carbon behavior and can be placed in structures using digitally*empowered processes such as 3-D printing. In doing so, the program strives to integrate cutting edge*discoveries in materials sciences, sensors and structural engineering. *** ***The proposal focuses on two broad areas: FIRST:*It purports to develop a novel class of fiber reinforced concretes called Eco-Friendly*Ductile Cementitious Composites (EDCC) that are self-healing, durable, low-carbon,*and damage tolerant up to 6% strain. It is further proposed to modify matrices*in EDCC with nano-particles and reinforce them with co-extruded recycled fibers*from waste streams (such as tires) modified with hydrophilic and pozzolanic nano-coatings.* In one application, hollow fibers are*proposed as reinforcement in EDCC; fibers that can carry controlled release biocides*capable of fighting biogenic corrosion of concrete in sewer pipes. Both*quasi-static and impact and blast loading tests are proposed. Finally, it is proposed*to develop 3-D printing protocols to place EDCC. SECOND: It is proposed to*develop sensors based on smart EDCC carrying conductive carbon fibers and*carbon nano-tubes. These piezo-resistive sensors will be further developed for chemical,*biological, scour and blast monitoring. Finally*FOUR technology demonstration projects are proposed including rehabilitation of a sewer pipe with controlled biocide*release EDCC, seismic strengthening of a school using sprayed EDCC, 3-D*printing of a low cost house with EDCC and a defense shelter built using highly*impact/blast resistant EDCC. These will be monitored using novel sensors described above. *** ***Over*the next five years, the proposed program of research is expected to provide a*total HQP training of 25 graduate student-years.**
智慧城市是将基础设施和服务整合在一起的城市,通过智能传感器和先进的数据科学,形成一个高效的城市生态系统,将制度、物理、社会和经济基础设施整合在一起。智慧城市中的混凝土基础设施不仅必须安全、可持续,还必须集成物联网(IoT)和信息通信技术(ICT),以实现运营效率、成本效益维护和寿命终结的可拆解性。该提案的主要目标是为智能城市的安全、可持续、数字化监控的混凝土结构的发展做出贡献。这些目标不仅适用于新建筑,也适用于需要恢复其失去的能力的老化结构,以及尚未老化但仍需要加强以抵御地震和火灾等灾害的结构。*** ***该方案侧重于开发高度耐损伤材料,这种材料利用纳米技术原理来描述自我修复、智能和低碳行为,并且可以使用3d打印等数字授权工艺放置在结构中。在此过程中,该项目努力整合材料科学、传感器和结构工程方面的前沿发现。*** ***该提案侧重于两大领域:第一:*它旨在开发一种新型纤维增强混凝土,称为环保*韧性胶凝复合材料(EDCC),具有自愈、耐用、低碳、*和高达6%应变的损伤容忍度。进一步提出用纳米颗粒修饰EDCC中的基体*,并用亲水性和火山灰纳米涂层改性的来自废物流(如轮胎)的共挤出再生纤维*来增强它们。在一个应用中,中空纤维被建议作为EDCC的增强材料;纤维可以携带可控释放的杀菌剂*,能够抵抗污水管道中混凝土的生物腐蚀。提出了准静态、冲击和爆炸载荷试验。最后,提出了开发3d打印协议来放置EDCC的建议。第二:提出了基于导电碳纤维和碳纳米管的智能EDCC传感器的开发。这些压阻传感器将进一步开发用于化学,生物,冲刷和爆炸监测。最后,提出了四个技术示范项目,包括使用可控的杀菌剂释放EDCC修复下水道管道,使用喷射EDCC对学校进行地震加固,使用EDCC 3d打印低成本房屋以及使用高度抗冲击/防爆EDCC建造防御避难所。这些将使用上述新型传感器进行监测。*** ***在未来五年内,拟议的研究计划预计将提供25个研究生年的HQP培训**
