In this episode of the Concrete Logic Podcast, Seth and Dan McCoy discuss aging concrete and how to responsibly treat and maintain it. They talk about the importance of maintaining existing infrastructure and extending the life of aging concrete structures. Dan shares his experience working on IDIQ contracts in Indiana, where they focus on addressing specific issues in aging concrete. They also discuss the use of nanosilica as a solution for healing and strengthening aging concrete. Nanosilica works by purging harmful chemicals and promoting the growth of calcium silicate hydroxide, which improves the strength and durability of the concrete. In this conversation, Dan McCoy discusses a unique project involving a tunnel that was repurposed as a walking trail. He explains the challenges of maintaining aging infrastructure and the importance of eliminating cold joints in concrete structures. Dan also shares his experience using hydrogels to repair cracks in concrete and highlights the potential of nanotechnology in the field. He emphasizes the need for sustainable and long-lasting infrastructure solutions.TakeawaysMaintaining existing infrastructure is crucial to extend the life of aging concrete structures.Nanosilica is a solution for healing and strengthening aging concrete by purging harmful chemicals and promoting the growth of calcium silicate hydroxide.Using nano-silica in structural patching can improve the bond strength and longevity of the repaired concrete.
