Waste-Derived Thermal Insulation Bricks from Kaolin–Sawdust–Periwinkle Shell Ash Composites: Multi-Response Taguchi–Grey Relational Optimization for Sustainable Construction
This study utilizes Taguchi design and Grey Relational Analysis to optimize a sustainable thermal insulation brick formulation composed of kaolin, sawdust, and periwinkle shell ash, achieving a 77.4% reduction in thermal conductivity and a compressive strength of 7.83 MPa that exceeds construction standards.
