MICROWAVE HEATING OF THE GEOPOLYMERS IN A CONSTRUCTION 3D PRINTER

Abstract

This MSc research thesis delves into the mechanical behavior of copolymer-based structures fabricated through 3D printing, specifically focusing on the transformative influence of microwave heating. Centered on geopolymers, recognized for their eco-friendly and sustainable attributes, the study aims to elucidate the nuances in stress and deformation dynamics introduced by microwave heating in the 3D printing process. A comprehensive literature review outlines the various applications of microwave heating within geopolymer chemistry, advancements in 3D printing technology, and materials science. This review synthesizes the concepts to establish a theoretical framework, enabling a deep understanding of the intricate interactions between the application of microwave energy and geopolymerization processes. Empirical data were collected through stress-strain experiments conducted on geopolymer samples subjected to microwave heating and conventional 3D printing techniques. This investigative approach required meticulous experimentation and systematic modification of parameters such as treatment duration, microwave energy exposure period, and the resultant voltage-strain profiles. These parameters were scrutinized to ascertain the impact of microwave heating on the mechanical performance of geopolymer structures. Findings from stress and strain tests provide reliable insights. It was observed that microwave heating alters the polymerization process, thereby influencing the material's response to external forces. A comparative analysis of stress-strain curves between specimens exposed to microwave radiation and those treated conventionally reveals differences in structural integrity and load-bearing capacities. Discussions elucidate these findings, pondering the implications for construction methodologies. Microwave heating emerges as a promising catalyst for enhancing the mechanical performance of geopolymer-based constructions. This revelation holds the potential to refine procedures for 3D printing recyclable building materials, optimizing them for better performance and sustainability.
