摘要:
混凝土作为应用最广泛的建筑材料，其耐久性越来越成为工程关注的重点，而基体裂纹损伤和内部钢筋锈蚀是影响混凝土耐久性的最主要原因。从引入外场的角度，为提高水泥基复合材料的耐久性和自修复效率提出了新的思路。为了解决传统微胶囊修复混凝土不可控、完全依赖外界环境变化的技术问题，提供了一种光磁耦合式自愈合混凝土的制备方法及其响应装置，这种混凝土在制备时加入了磁性微胶囊和导光装置，在光热场和磁场的协同作用下，使得微胶囊能够及时有效地破裂，达到最佳的修复效果。
Abstract:
As the most widely used building material, the durability of concrete is increasingly becoming the focus of engineering attention, while matrix crack damage and internal reinforcement corrosion are the most important causes of concrete durability. In this paper, new ideas are proposed to improve the durability and self-healing efficiency of cementitious composites from the perspective of introducing external fields. In order to solve the technical problem that traditional microcapsules repair concrete are uncontrollable and totally dependent on external environmental changes, a preparation method of optomagnetically coupled self-healing concrete and its response device are provided. The self-healing concrete is prepared with magnetic microcapsules and light-guiding device, which enables the microcapsules to rupture in a timely and effective manner under the synergy effect of light-heat field and magnetic field to achieve the best repair effect.
