Center for Science and Technology of Advanced Cement-Based Materials

西北大学先进水泥基材料科学与技术中心是一个跨学科的合作项目，涉及来自西北大学、伊利诺伊大学香槟分校、普渡大学、密歇根大学和国家标准与技术研究院（NIST-前身为NBS）的研究小组。该中心的主任将是西北大学的Surendra P. Shah教授。本中心的研究计划有两个基本的互补目标。首先是对目前可用的胶凝材料提供更全面的了解，从而促进更有效和高效的使用。二是为性能大幅提升的新材料设计提供全面依据。研究计划包括：1)胶凝材料的化学和物理（流变学和凝结过程，硅酸盐和铝酸盐水泥化学，固溶界面化学，新型水泥化学，聚合物-水泥复合材料）；2)加工科学（预硬化加工，流变过程，温度和压力的影响，微观结构和增强几何形状的影响，以及新的加工技术）；3)微观结构分析（反应产物性质、孔隙结构、固-固界面、组分分布）；4)材料性能（断裂过程和机制、扩散和输运现象、长期变形、环境和热稳定性）；5)纤维增强（纤维几何和分布、纤维-基质相互作用和微观力学）。这些领域是相互依存的，每个领域都将通过对反应、过程和性质的数学建模来增强。生成的模型将用于预测性能分析，并作为开发新材料、新工艺和新系统的工具。它们将作为水泥基材料设计、制造和使用方式变化的基础。中心计划的外展活动包括出版物和演讲、会议、工业附属项目、大学-工业研究项目和短期课程。

The Center for Science and Technology of Advanced Cement-Based Materials at Northwestern University is a collaborative interdisciplinary effort involving research groups from Northwestern University, the University of Illinois at Champaign- Urbana, Purdue University, the University of Michigan, and the National Institute of Standards and Technology (NIST--formerly NBS). The director of the Center will be Professor Surendra P. Shah of Northwestern University. There are two basic complementary objectives to the research plan of the Center. The first is to provide a more complete understanding of the cementitious materials that are currently available, thus fostering more effective and efficient use. The second is to provide a comprehensive basis for the design of new materials with greatly improved properties. The plan of research includes: 1) the chemistry and physics of cementitious materials (rheology and setting processes, chemistry of silicate and aluminate cements, solid-solution interface chemistry, new cement chemistries, and polymer-cement composites); 2) processing science (prehardening processing, rheological processes, influence of temperature and pressure, influence of microstructure and reinforcement geometries, and novel processing techniques); 3) microstructural analysis (properties of reaction products, pore structure, solid-solid interfaces, and component distributions); 4) material properties (fracture processes and mechanisms, diffusion and transport phenomena, long-term deformation, environmental and thermal stability); and 5) fiber reinforcement (fiber geometry and distribution, fiber-matrix interactions, and micromechanics). These areas are interdependent and each will be augmented by mathematical modelling of reactions, processes and properties. The models generated will be used for predictive performance analyses and as a tool to develop new materials, processes, and systems. They will serve as a basis for introducing changes in the way cement-based materials are designed, fabricated and used. Outreach activities planned by the Center include publications and presentations, conferences, an industrial affiliates program, university-industry research projects and short courses.
