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

描述：该奖项是为了支持材料研究实验室的R.I. Malek博士和宾夕法尼亚州立大学材料科学荣誉教授Della Roy博士以及埃及亚历山大大学研究生学习与研究所材料科学系系主任Essam El-Rafey博士的合作项目。这些科学家建议研究古建筑和古迹退化的机制，并为修复找到科学依据。美国和埃及的调查人员计划在适当的监督下收集埃及受损纪念碑的样本。他们计划诊断这些样品的劣化机制，并在相同条件下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、固态魔角旋转核磁共振光谱（MAS NMR）、拉曼和红外光谱，以及更常规的方法，如颜色、孔隙率、吸水率、体积比重、硬度、抗压强度、弹性模量、热膨胀和电导率。他们将尝试用几种粘合剂（包括水泥浆液、地聚合物、胶凝聚合物共混物和磷酸盐粘合剂）确定这些样品的适当修复机制。将测试这些粘合剂与砌体的相容性、寿命、附着力和颜色。范围：该提案涉及一个重要领域，即研究古代建筑和纪念碑退化的机制及其修复方法。本项目将基础科学知识运用到实践中，并结合现场实际数据进行验证。这两位美国pi是材料研究、表征和材料性能分析方面的专家。他们的研究所有一流的研究设施。这位埃及合作科学家就职于埃及大学中最受尊敬的研究单位之一。国际合作是经过深思熟虑的，人们期望它们将朝着互利的方向发展，并产生有益的结果。该项目符合国际情报机构支持互利合作研究项目的标准。该项目的资金由国际项目部和土木与机械系统部提供。

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.
