1智能混凝土的定义和发展历史
智能材料,指的是“能感知环境条件,做出相应行动”的材料。它能模仿生命系统,同时具有感知和激励双重功能,能对外界环境变化因素产生感知,自动作出适时。灵敏和恰当的响应,并具有自我诊断、自我调节、自我修复和预报寿命等功能。智能混凝土是在混凝土原有组分基础上复合智能型组分,使混凝土具有自感知和记忆,自适应,自修复特性的多功能材料。根据这些特性可以有效地预报混凝土材料内部的损伤,满足结构自我安全检测需要,防止混凝土结构潜在脆性破坏,并能根据检测结果自动进行修复,显著提高混凝土结构的安全性和耐久性。正如上面所述,智能混凝士是自感知和记忆、自适应。自修复等多种功能的综合,缺一不可,以目前的科技水平制备完善的智能混凝土材料还相当困难。但近年来损伤自诊断混凝土、温度自调节混凝土。仿生自愈合混凝土等一系列智能混凝土的相继出现;为智能混凝土的研究打下了坚实的基础。
1.1损伤自诊断混凝土
自诊断混凝土具有压敏性和温敏性等自感应功能。普通的混凝土材料本身不具有自感应功能,但在混凝土基材中复合部分其它材料组分使混凝土本身具备本征自感应功能。目前常用的材料组分有:聚合类、碳类、金属类和光纤。其中最常用的是碳类、金属类和光纤。下面主要介绍2种当前研究比较热门的损伤自诊断混凝土。

1. Intelligent concrete definition and the history of the development

Smart materials, means "to perceive environmental conditions, make the appropriate action" Materials. It can imitate life-support systems, but also has the double function of perception and motivation, can change the external environment factors perceived to automatically make a timely manner. Sensitive and appropriate response and self-diagnosis, self-regulating, self-repair and life prediction functions. Intelligent Concrete components are in the concrete foundation on the original composite intelligent components, the concrete self-perception and memory, adaptive, self-healing properties of multifunctional materials. Based on these characteristics can effectively forecast the internal damage of concrete materials to meet the structure of self-safety testing required to prevent potential brittle failure of concrete structures and test results in accordance with automatic repair, significan
