Concrete continuously undergoes a process known as carbonation, where it naturally absorbs carbon dioxide without altering its structural integrity. This process is perpetual in concrete structures and is not a recent discovery.The phenomenon of carbonation has been recognized by the UN in an IPCC climate report, acknowledging concrete’s ability to sequester carbon. There exist established procedures and benchmarks for quantifying the carbon uptake of concrete.Over the course of its existence, a concrete structure can reabsorb approximately 20% of the carbon emissions it originally produced. Notably, around half of this absorption occurs within the first 25 years, assuming the structure has a 100-year lifespan.
