According to an engineer and researcher at the B.C. Institute of Technology (BCIT), global climate change is expected to lead to the increased deterioration of concrete infrastructure in Canada in the future.
Sudip Talukdar, civil engineering program coordinator in BCIT’s School of Construction and the Environment, did computer simulations of the effect of climate change on concrete in Vancouver and Toronto.He found that concrete is more vulnerable to climate change-induced deterioration in one of the cities than the other, because of different geographic location and climate.
Although most scientists believe increasing greenhouse gas emissions are affecting the Earth’s climate, there has been little investigation until recently of the impact of climate change on concrete infrastructure, says Talukdar.
But researchers have been catching up, and more attention is being paid to what happens when an increase in greenhouse gasses and higher heat and humidity work their way into concrete infrastructure.
