Effective Concrete Crack Closure Through Innovative Hybrid PET Tendons

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.
