EAGER: Influence of source location and type of demolition waste in New York City and Istanbul on the properties and sustainability of concrete with recycled concrete aggregate

这个更新的合作研究项目支持正在进行的美国-土耳其试点计划。 来自美国纽约城市学院（CCNY）和土耳其伊斯坦布尔技术大学（ITU）的调查人员将调查和比较两国在混凝土中使用RCA的潜力和影响。该项目计划包括美国和土耳其的PI相互访问对方的实验室，以及在项目期间进行为期六个月的研究生交流。近距离的工作环境将使两个团队中的个人接触到截然不同的文化和科学环境，并促进美国和土耳其研究人员之间更密切的关系。该研究项目的一个主要目标是根据科学发现开发一种生产可靠的结构RCA混凝土的系统程序，该程序将与传统NA混凝土具有成本竞争力，并将减少混凝土生产对环境的影响。在微观尺度上研究材料所需的实验设施在纽约中央研究中心，而全面的宏观尺度结构测试设施在国际电联。与这两个市场的再生混凝土骨料生产商和结构混凝土制造商合作，将提供一个独特的机会，在广泛的现实生活条件和限制下开发解决方案。

This renewal collaborative research project supports an ongoing US-Turkey pilot program. Investigators from the City College of New York (CCNY) in the U.S. and Istanbul Technical University (ITU) in Turkey will investigate and compare the potential for, and impacts of, using RCA in concrete in both countries. The project plan includes reciprocal visits by the U.S. and Turkish PIs to each other's laboratories as well as a six month graduate student exchange during the life of the project. The close working environment will expose individuals in both teams to very different cultural and scientific environments and foster closer relations between US and Turkish researchers. A main goal of the research project is to develop, based on scientific findings, a systematic procedure for producing reliable structural RCA concrete that will be cost-competitive with conventional NA concrete and will reduce the environmental impact of concrete production. Experimental facilities needed to study materials at the micro-scale are at CCNY while facilities for full-scale macro-scale structural testing are at ITU. Working with recycled concrete aggregate producers and manufacturers of structural concrete in these two markets will provide a unique opportunity to develop solutions across a wide spectrum of real-life conditions and constraints.
