University of Tokyo Researchers Develop Method to Quantify CO2 Absorption in Concrete

Researchers at the University of Tokyo have developed a new method to measure the amount of carbon dioxide (CO2) absorbed by concrete from both atmospheric and industrial sources. This technique allows for the precise quantification of carbon uptake, providing a standardized approach for tracking carbon levels within concrete materials.

The research team designed this method to distinguish between different sources of carbon, which helps clarify how much CO2 concrete sequesters over its lifespan. By identifying the specific ratios of carbon absorbed, the scientists provide a framework that could assist in the development of carbon accounting and trading systems. This process relies on analyzing the chemical interactions between concrete and its surrounding environment to determine the total volume of CO2 captured. These findings offer a technical baseline for industries looking to monitor the environmental impact of concrete infrastructure more accurately.
