Early CO2 capturing mortar by incorporating a new potential carbide lime waste under controlled CO2 curing

Early-age cement paste or mortar can be enhanced by curing it in a CO2 chamber. The study was initiated with investigation on the optimum compressive strength by replacing cement to carbide lime with 0, 5, 10, 15 and 20% of Carbide Lime Waste (CLW) content. The desired CLW mortar at 28 normal curing...
