Reports on CO2 Uptake from the Carbonation of Concrete - Introduction

In the project "CO₂  Uptake during the Concrete Life Cycle", running from 2003 to 2005, a total of 5 reports were published by the project participants in 2005.

On the following pages these reports are described and abstracts are given.

Approximately half of the CO₂ emissions from cement production stems from the calcination of limestone. Theoretically, hardened concrete binds approximately the same amount of CO₂ in the carbonation process.

The reports give the background for including CO₂ Uptake during a full life-cycle of concrete. Furthermore, a model for Carbonation. Furthermore, a model for CO₂ Uptake is presented depending on theconcrete quality, application and exposure conditions. This model is validated by means of laboratory experiments.
