Abstract

Geopolymers, recognized as an ecological alternative to cement concrete, are gaining more and more interest from researchers and the construction industry. Due to the registrable electrical conductivity, this material also attracts the interest of other fields of science and industry as a potential functional material. The article discusses the used geopolymer material, created on the basis of metakaolin and waste Cathode Ray Tubes (CRT) glass, reinforced with ultra-long in-house carbon nanotubes (CNT), in the context of its use as a smart material for Structural Health Monitoring. Long in-house made carbon nanotubes were added to enhance the electrical conductivity of the geopolymer. The impedance spectroscopy method was applied to investigate the conductive properties of this material. The paper shows the microscopic and mechanical characteristics of the materials and presents the results of promising impedance spectroscopy tests.

摘要

地质聚合物作为水泥混凝土的一种生态替代品，正越来越受到研究人员和建筑行业的关注。由于其具有可测量的导电性，这种材料作为一种潜在的功能材料，也吸引了其他科学和工业领域的兴趣。本文讨论了一种基于偏高岭土和废弃阴极射线管（CRT）玻璃制成的地质聚合物材料，该材料用超长的自制碳纳米管（CNT）增强，用于结构健康监测的智能材料。添加了自制的长碳纳米管以提高地质聚合物的导电性。采用阻抗谱方法研究了该材料的导电性能。本文展示了材料的微观和力学特性，并给出了有前景的阻抗谱测试结果。
