Researchers from the University of Tokyo and Nagoya University have found that concrete structures in Japan capture and store approximately 14% of the carbon dioxide emissions released during cement production. The research, which the team believes offers insights into mitigating the environmental impact of one of the world's most carbon-intensive industries, was recently published in the Journal of Cleaner Production.With cement production responsible for about 8% of global carbon dioxide emissions, the team was prompted to explore ways to reduce the materials carbon footprint. As the primary product of cement, concrete naturally absorbs carbon dioxide throughout its lifecycle through a process known as carbonation; a reaction that can contribute to the deterioration of reinforcing steel in buildings but also enables concrete structures to act as carbon sinks.Related on Archinect: Princeton researchers develop concrete 3D printing method inspired by ancient fish scales.Image cr...
