Enhancing carbonation and strength of MgO cement through 3D printing

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 nanoclays methylcellulose produce cylinders with exposed open-to-air closed (solid) infills. results showed significant increases in at 3 28 days compared conventionally cast specimens. This attributed higher surface area increase porosity caused by high early water evaporation, both led CO2 intake.
