Abstract:
This project evaluates the viability of 3D printed cementitious composites with the inclusion of microencapsulated phase change materials (mPCM). An experimental program was carried out to identify the effect of mPCM on the printability, mechanical, and thermal properties of cementitious printing inks. Results demonstrated that at low volume inclusions the addition of mPCM increased both flowability and compressive strength of the material. Higher volume increases demonstrated that the mPCM decreased the printability resulting in lower compressive strengths and thermal conductivities. Finally, a thermal network model was developed for 3D printed building components that are charged with mPCM materials. The study shows that microencapsulated PCM materials have good potential to be used in 3D printable cementitious mixtures for improving the thermal and energy performance of 3D printed buildings.
