The objective of this collaborative US-Turkish pilot research project is to investigate the use of Recycled Concrete Aggregate (RCA) obtained from demolition waste as a substitute for natural aggregate (NA) for the production of new concrete. The topic has been studied for many decades; however, very little progress has been made toward the widespread use of RCA in good-quality concrete for new structures. The research team is uniquely qualified to conduct the bilateral cooperative research and consists of experts in Recycled Concrete Construction Materials at CUNY City College (CCNY) and Structural Engineering at Istanbul Technical University (ITU). 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. This project brings together researchers from the US and Turkey and will include reciprocal visits by the two US and two Turkish PIs to each other's laboratories as well as a three month graduate student exchange during the 12 month project. This 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. CCNY is a Minority Serving Institution (and Hispanic Serving Institution) and the exposure of STEM students at CCNY to researchers from Turkey and vice versa will be immensely valuable to promoting cultural understanding in two of the world's greatest cities. Also both New York City and Istanbul have unique urban infrastructure construction markets. Working with recycled concrete aggregate producers and manufacturers of structural concrete (Ready Mix companies or batching facilities at construction sites) in these two markets will provide a unique opportunity to develop solutions across a wide spectrum of real-life conditions and constraints.

这个合作的美国-土耳其试点研究项目的目的是调查使用的混凝土骨料（RCA）从拆除废物获得的天然骨料（NA）的替代品，用于生产新的混凝土。该主题已经研究了几十年;然而，在新结构的高质量混凝土中广泛使用RCA的进展甚微。该研究小组是唯一有资格进行双边合作研究的，由纽约市立大学（CCNY）的混凝土建筑材料专家和伊斯坦布尔技术大学（ITU）的结构工程专家组成。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。该项目汇集了来自美国和土耳其的研究人员，并将包括两个美国和两个土耳其PI对彼此实验室的互访，以及在12个月的项目期间进行为期三个月的研究生交流。这种紧密的工作环境将使两个团队中的个人接触到非常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。CCNY是一个少数民族服务机构（和西班牙裔服务机构），CCNY的STEM学生接触来自土耳其的研究人员，反之亦然，对于促进世界上两个最大城市的文化理解将具有巨大的价值。此外，纽约市和伊斯坦布尔都有独特的城市基础设施建设市场。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（即拌公司或建筑工地的预拌设施）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条件下开发解决方案。
