混凝土材料在四个结构层次上进行研究,这四个层次为原子-分子、细观、粗观和宏观层次料。对前三个层次上组分、结构、界面和宏观力学行为之间的关系则进行表面化学、细观断裂力学、固体统计力学和材料体系的计算机模拟等多学科的研究。本文概括了基本概念及研究方法,并报导了所得到的具有独特的力学性质的新材料。混凝土材料的力学行为按其使用条件进行综合设计是可行的,前景光明。本文提出了从多层次的组分、结构和界面预报力学行为,从组成材料和工艺过程预报多层次的组分、结构和界面状态,以及预报在特殊条件下的使用寿命是混凝土材料科学和工程的三大任务,其中后两个预报是建筑在第一个预报发展基础上的。
Concrete materials are studied at four levels of structure: atomic-molecular, meso, coarse, and macroscopic levels. The relationship among the components, structures, interfaces, and macromechanical behaviors of the first three levels is the multidisciplinary study of surface chemistry, meso fracture mechanics, solid statistical mechanics, and computer simulation of material systems. This article summarizes the basic concepts and research methods, and reports the new materials with unique mechanical properties. The comprehensive design of the mechanical behavior of concrete materials according to their conditions of use is feasible and promising. This paper proposes the prediction of mechanical behavior from multiple levels of components, structures, and interfaces, the prediction of multi-level composition, structure, and interface states from the constituent materials and processes, and the prediction of service life under special conditions for concrete materials science and engineering. Among the three major tasks, the latter two forecasts are based on the first forecast development.
