Concrete Coating Developed to Stabilize Structures Against Earthquakes

11 October 2017

Researchers from the University of British Columbia have developed a coating for concrete meant to stabilize and help buildings and structures withstand powerful earthquakes.

The material, called EDCC, is a strong coating applied to walls in a roughly 10-mm layer to reinforce buildings against the force of seismic shocks. According to researchers, structures treated with the material during testing were capable of surviving simulated earthquakes with magnitudes as strong as 9.0-9.1.

With ingredients that include polymer-based fibers, flyash and other industrial additives, EDCC is thought to be as strong as steel and researchers are convinced that the material will save lives.

Likewise, researchers believe the new material will also impact the environment by reducing the amount of cement necessary to create such structures.

According to Civil Engineering Professor Nemy Banthia, who supervised the work, “This is quite an urgent requirement as one tonne of cement production releases almost a tonne of carbon dioxide into the atmosphere, and the cement industry produces close to seven percent of global greenhouse gas emissions.”

Researchers believe that applying EDCC won’t be exclusive to earthquake-proofing structures and will find possible applications in the construction of pipelines, offshore platforms, industrial flooring, pavements and blast resistant structures.
