Abstract

The main goal of this research is to develop a carbonated cementitious material (CCMs) mix design and demonstrate its rapid stiffening for manufacturing 3D printed or precast elements for building construction (i.e., concrete with enhanced durability and CO2 capture efficiency). The material development employs hydrated Ca(OH)2, and its distinct reaction with CO2 to form CaCO3. Different formulations and additives including polymer materials enable the thermomechanical properties that give these CCMs 3D printability comparable with cement materials used for similar applications. Printable and castable CCM formulations were successfully developed and demonstrated to mineralize CO2 to form up to 57% CaCO3.
