The article delves into the enduring challenge of cracking in concrete structures, examining innovative solutions, with particular emphasis on the development and assessment of a novel Tendon (the Side PET Hybrid Tendon (SPHT)). Traditional approaches to crack closure often prove inadequate in terms of both effectiveness and cost efficiency. Through the fusion of Kevlar®, PET, and Kanthal wire, the SPHT exhibits promising abilities in effectively sealing cracks. Laboratory trials showed significant reductions in crack sizes when the tendons were activated, achieving reductions of 60% to 80%. This underscores their potential to greatly enhance the durability of concrete structures. The SPHT presents a feasible remedy for addressing cracking in concrete structures, offering a pathway towards enhanced longevity and diminished maintenance requirements.
