Methodology for Assessing Long-Term Deformation Influence on Geopolymer Composite Microstructure
Summary of Doctoral Thesis
Rihards Gailītis, Riga Technical University, Latvia
The Thesis is focused on methodology development for microstructure assessment of plain and fiber-reinforced geopolymer composites after long-term property determination in compression, tension and three-point bending. Plain and reinforced with steel, polyvinyl alcohol, polypropylene and carbon fibers geopolymer composites have been tested for long-term properties in compression, tension and three-point bending. Creep properties have been determined in a linear state. Shrinkage properties have been determined simultaneously with the creep strains. For microstructure assessment, polished section specimens have been used and assessed in a scanning electron microscope. As a result, one national patent and one patent application have been developed that show microstructure assessment and long-term determination.
