Crack Blunting Damaged and Deteriorated Concrete with Colloidal Silica

Repair Cracks and Crack Blunting in Concrete with Hydrogels

Join Jon as we explore a remarkable innovation in the field of concrete repair that leverages the unique properties of hydrogels to create a phenomenon known as crack blunting in cracked and deteriorated concrete structures.

By blunting cracks in cracked and deteriorated concrete, the resiliency to crack propagation or the continuation of cracking in concrete is reduced.

This presentation aims to provide a comprehensive understanding for civil engineers, material scientists, and asset managers on how hydrogels can be used to extend the life and enhance the durability of concrete infrastructures.

The purpose of employing colloidal nano silica hydrogels within concrete structures is to mitigate the effects of crack propagation, a common yet significant issue that compromises the structural integrity and longevity of concrete.

The Objectives Include: - Defining a concrete crack and Introducing the mechanics behind crack propagation in concrete structures. Understanding the concept and benefits of crack blunting. - Examining the role of hydrogels in achieving crack blunting and, consequently, in concrete repair. - Now we are going to get deep into the mechanics of materials here as well as the material science. And while I will be giving basic information, my expectation is that my audience has done a little bit of homework on this subject. To some I might sound like, “a Physics Professor that starts the first day of class on Chapter 9.”
