The effects of these additives on compressive and flexural strengths were evaluated using an L-16 orthogonal array, and optimal mixes were determined. The hybrid model attained a compressive strength of 32.23 MPa and a flexural strength of 1.41 MPa, demonstrating remarkable prediction accuracy (R-2 > 0.95). The integrated approach also allows cost-effective creation of multifunctional gypsum composites with improved mechanical and electromagnetic properties, in line with advanced construction material development.eninfo:eu-repo/semantics/closedAccessGypsumGlass FiberCarbon BlackMagnetiteTaguchiCuckoo Search AlgorithmArticle10.1016/j.jobe.2025.1129622-s2.0-105005808184
