Résumé

Structural health monitoring will revolutionize infrastructure repair by enabling targeted preventative maintenance. To achieve this goal, new self-sensing materials are needed with high strength, piezoresistivity, scalability, and affordability. These four properties can be achieved with potassium-activated inorganic polymers. In this study, new relationships have been discovered between the composition of these materials and their self-sensing capabilities. Alkali-activated materials form natural composites with high self-sensing capabilities without the need for conductive fiber additives. The intrinsic piezoresistivity of potassium-activated inorganic polymers surpasses the best cement-carbon nanotube composites without the added cost and scalability limitations. This positions the materials as the best candidate for future self-sensing construction materials for structural health monitoring applications.
