Description
3D printing of cementitious materials, as an emerging construction technology, faces challenges in both mechanical performance and sustainability. Conventional mixture designs rely on high cement contents, leading to increased CO2 emissions, while printed elements often exhibit brittle behavior with limited crack resistance and reduced post-cracking performance. This study investigates the development of low-carbon 3D printed cementitious composites using environmentally friendly supplementary cementitious materials (SCMs) and fillers, combined with fiber reinforcement to enhance mechanical performance. Locally available SCMs and fillers were incorporated to significantly reduce cement content (>40%) and improve sustainability. Fiber reinforcement was introduced to mitigate brittleness and enhance ductility and crack resistance. The results demonstrate that integrating low-carbon material design with fiber reinforcement can enable sustainable and resilient 3D printed cementitious systems.
Biography
Nima Mahmoudzadeh Vaziri is a Ph.D. candidate in Civil Engineering at Missouri University of Science and Technology and a certified civil and concrete materials engineer with four years of combined academic and professional experience. His research centers on the development of low-carbon, fiber-reinforced, 3D-printable cementitious composites with enhanced rheological behavior, mechanical performance, and structural efficiency.
As a research assistant collaborating with the U.S. Army Engineer Research and Development Center (ERDC), he has developed sustainable, field-deployable mortar systems utilizing locally available materials for construction-scale additive manufacturing. His work involves comprehensive experimental evaluation of fresh, rheological, and hardened properties, along with mixture optimization to improve buildability and minimize defects.
He has co-authored several peer-reviewed publications in journals such as the Journal of Building Engineering and ACI Materials Journal. Additionally, he has experience in bridge rehabilitation, construction inspection, and teaching materials laboratory instruments.
