Abstract
This study explored the use of Carbide Lime Waste (CLW) in mortar production and its exposure to controlled CO2 curing for 24 hours. The results indicate that CLW mortar under CO2 curing has improved compressive strength and early CO2 capturing performance due to the reaction between Ca (OH)2 in CLW and CO2 gas. With a cement replacement rate of 20, a 60% solid carbonates precipitation was recorded after just 7 days of curing. In general, the longer the curing durations, the higher the CO2 capturing capability. Further investigations into the long-term mechanical and durability properties are recommended to assess its feasibility for practical applications. Re-utilization of waste materials like CLW can make significant strides towards more eco-friendly and sustainable practices.
