Development of CO2-Infused Concrete for the Construction Industry
摘要
The worldwide construction is the biggest contribution to carbon dioxide (CO2). To handle this problem related to the environment, this study flashlights a new approach of inculcating CO2 in the form of dry ice in concrete mix. Incorporating dry ice in the range of 10–30%, the result investigates the effect of CO2 on compressive strength of concrete. In focus on mixture, the one compliant 20% dry ice demonstrated the higher compressive strength. Prepared specimen with dry ice is checked for durability with compression strength test after immersion in acidic and alkaline condition. The main ingredient of concrete is cement having significant capacity to absorb CO2. When CO2 is added to concrete, acid–base neutralization reaction occurs with calcium hydroxide, a by-product of cement hydration, causing a chemical change to form calcium carbonate. These findings open the door to widespread adoption of CO2 reduction as the industry moves toward sustainable development with eco-friendly infrastructure.
