US-Egypt Cooperative Research: Restoration and Preservation of Ancient Buildings and Monuments

9911964Malek描述：该奖项是为了支持由材料研究实验室RI.Malek博士、宾夕法尼亚州立大学材料科学荣誉退休教授Della Roy博士和埃及亚历山大市亚历山大市大学研究生院材料科学系主任Essam El-Rafey博士共同开展的一个合作项目。这些科学家建议研究古建筑和古迹退化的机理，并为修复寻找科学依据。美国和埃及调查人员计划在适当的监督下，收集埃及受损古迹的样本。他们计划诊断这些样品的变质机制，并在相同条件下将它们与其他未损坏的样品进行比较。诊断方法将包括X射线衍射法、固态魔角旋转核磁共振谱(MAS核磁共振)、拉曼光谱和红外光谱，以及更传统的方法，如颜色、孔隙率、吸水率、体积比重、硬度、抗压强度、弹性模数、热膨胀和导电率。他们将尝试用几种粘结剂来确定这些样品的适当修复机制，包括水泥灌浆、土聚合物、水泥聚合物混合物和磷酸盐粘结剂。将测试这些粘结剂与砖石、寿命、粘结力和颜色的兼容性。范围：该提案涉及一个重要领域，即研究古建筑和纪念碑的退化机理和修复方法。该项目将基本的科学知识带到实践中，并用实际的现场数据进行验证。这两位美国PI是材料研究、表征和材料特性分析方面的专家。他们的研究所拥有一流的研究设施。这位埃及合作科学家在埃及大学中最受尊敬的研究单位之一工作。国际合作构思良好，预期它们将朝着互利共赢的方向发展，并将产生有益的结果。该项目符合支持互惠合作研究项目的INT标准。该项目的资金由国际方案司和土木工程与机械系统司提供。

9911964Malek Description: This award is to support a cooperative project by Dr. R.I. Malek, Materials Research Laboratory and Dr. Della Roy, Professor (Emeritus) of Materials Science at Pennsylvania State University, and Dr. Essam El-Rafey, Head, Materials Science Department, Institute of Graduate Study and Research, Alexandria University, Alexandria, Egypt. These scientists propose to study the mechanisms of deterioration of ancient buildings and monuments, and to find scientific basis for restoration. The US and Egyptian investigators plan to collect, with appropriate supervision, samples of damaged monuments in Egypt. They plan to diagnose the deterioration mechanism of these samples and compare them to other non-damaged samples under the same conditions. The diagnosis methods will include X-ray diffraction, solid state Magic Angle Spinning Nuclear Magnetic Resonance Spectroscopy (MAS NMR), Raman and Infrared Spectroscopy, as well as more conventional methods such as color, porosity, water sorption, bulk specific gravity, hardness, compressive strength, modulus of elasticity, and thermal expansion and conductivity. They will attempt to determine appropriate repair mechanisms for these samples with several binders including cement grout, geopolymers, cementic polymer blends, and phosphate binders. The compatibility of these binders with the masonry, longevity, adhesion, and color will be tested.Scope: The proposal addresses an important area, that of study of the mechanisms of deterioration of ancient buildings and monuments and means of their restoration. The project brings basic scientific knowledge to practice with actual field data for verifications. The two US PIs are experts in materials research, characterization, and analysis of material properties. They have excellent research facilities at their institute. The Egyptian collaborating scientist is at one of that country's most respected research units in Egyptian universities. The international collaboration is well conceived and the expectation is that they will proceed to mutual benefit and will produce useful results. This project meets INT criteria for support of mutually beneficial cooperative research projects. Funding for this project is provided by the Division of International Programs and the Division of Civil and Mechanical Systems.
