Carbon Storage through Concrete Block Carbonation

Hilal El-Hassan and Yixin Shao
Abstract—The effect of initial curing on carbonation curing of lightweight concrete masonry units (CMU) was examined. Initial curing was performed from 4 to 18 hours at a relative humidity of 50% and temperature of 25°C. Based on cement content, four-hour carbonation curing allowed concretes to uptake 22% to 24% CO2 with initial curing and 8.5% without initial curing, while prolonged 4-day carbonation recorded an uptake of 35%. Carbonation curing can replace steam curing in CMU production to accelerate hydration and recycle cement kiln CO2 in a beneficial manner.

Index Terms—Concrete masonry unit, curing, carbonation, carbon uptake.
