Abstract
Magnesium oxide (MgO), which develops physical strength through carbonation, is a potential alternative to carbon intensive Portland cement. In this paper, we examined whether 3D printing could improve carbonation and compressive strength. The rheology of MgO paste was modified using mixtures of nanoclays and methylcellulose to produce cylinders with exposed open-to-air and closed (solid) infills. The results showed significant increases in strength at 3 and 28 days compared to conventionally cast specimens. This was attributed to higher exposed surface area and increase in porosity caused by high early water evaporation, both of which led to higher CO2 intake.
