CRACKING-RESISTANT CONCRETE FOR DURABLE COASTAL STRUCTURES

Concrete in coastal environments is prone to cracking caused by shrinkage, which can compromise structural integrity and shorten the service life of bridges, pavements, and other infrastructure. This project investigates combining internal curing materials with recycled steel fibers salvaged from scrap tires as a way to reduce shrinkage, resist crack formation, and improve the overall durability of coastal concrete structures. The research aims to produce practical material selection guidelines and mix design recommendations, while also exploring how recycled steel fibers could partially or fully replace conventional steel reinforcement in pavement applications, offering a more sustainable and cost-effective solution.
