项目摘要
The purpose of this study was to develop the rational prediction method of the durability of the structures made of High Performance Concrete. Following results were obtained through this research.Micromechanical model for both water transport in concrete and associated volumetric change of concrete was made and improved. Simple constitutive law and cracking criteria of concrete under restrained shrinkage was obtained from experiment. Coupling these material models, FEM computer program was developed which can predict drying shrinkage cracking in concrete structures.Heat generation model of cement based on the mineral component was developed. Strength development model was also formulated on the basis of the unified concept. These were improved so that it can be applied to cement, blast furnace slag and fly-ash concrete. Design method for thermal crack resistance of High Performance Concrete was proposed.
这项研究的目的是开发高性能混凝土结构的耐用性的合理预测方法。通过这项研究获得了以下结果。对混凝土中水转运的微力学模型以及相关的混凝土变化和改进。从实验中获得了简单的本构定律和混凝土的破裂标准。耦合这些材料模型,开发了FEM计算机程序,可以预测混凝土结构中的干燥收缩裂纹。基于矿物质成分的水泥生成模型。还基于统一概念制定了力量发展模型。这些得到了改进,以便可以将其应用于水泥,爆炸炉炉渣和飞灰混凝土。提出了高性能混凝土热裂纹电阻的设计方法。
