混凝土是一种不断发展的材料,甚至高性能混凝土的定义也正随着时间的推移而发生变化。本文所说的混凝土材料的高性能特性是指那些直接影响我们生活质量的民用基础设施的理想耐久性、回弹性和可持续性的特性。这些特性包括拉伸延展性、自体裂缝宽度控制和材料的“绿色”环保性。此外,智能功能应旨在通过响应结构周围环境的变化来提高基础设施的耐久性、回弹性和可持续性以实现其理想功能,从而使材料的行为方式更类似于某些生物材料。本文基于工程水泥基复合材料(ECC)的最新研究进展,提出可以设计出具有高性能兼智能多功能性的混凝土材料,并且其具有满足 21 世纪民用基础设施预期需求的潜力。本文重点介绍了 ECC 的相关特性以及未来研究的方向。

The energy consumption of crushing is directly affected by the mechanical properties of cement materials. This research provides a theoretical proof for the mechanism of the stress relaxation of cement clinkers under high temperature. Compression stress relaxation under various high temperatures is discussed using a specially developed load cell, which can measure stress and displacement under high temperatures inside an autoclave. The cell shows that stress relaxation dramatically increases and that the remaining stress rapidly decreases with an increase in temperature. Mechanical experiments are conducted under various temperatures during the cooling process to study the changes in the grinding resistance of the cement clinker with temperature. The effects of high temperature on the load-displacement curve, compressive strength, and elastic modulus of cement clinkers are systematically studied. Results show that the hardening phenomenon of the clinker becomes apparent with a decrease in temperature and that post-peak behaviors manifest characteristics of the transformation from plasticity to brittleness. The elastic modulus and compressive strength of cement clinkers increase with a decrease in temperature. The elastic modulus increases greatly when the temperature is lower than 1000 °C. The compressive strength of clinkers increases by 73.4% when the temperature drops from 1100 to 800 °C.
