John C. Matthews

John C. Matthews is a Senior Professor at Louisiana Tech University, where he works across civil, environmental, materials, and systems engineering. His research centers on advanced geopolymer materials, including ternary blended geopolymer concrete for military airbase pavements, fly ash-based 3D printing, and refractory formulations. He also investigates radiation-shielding composites using bismuth trioxide and mill scale, fiber-reinforced high-strength geopolymer concrete, and robotic systems for structural integrity assessment. His recent work integrates environmental life cycle assessment and construction traction prediction for pipeline repair.
