Development of GGBS-Based Geopolymer Concrete Incorporated with Polypropylene Fibers as Sustainable Materials

Geopolymer concrete, because of its less embodied energy as compared to conventional cement has paved the way for achieving sustainable development goals. In this study, an effort was made optimize quality characteristics or responses, namely, workability, and compressive flexural strengths Ground Granulated Blast-furnace Slag (GGBS)-based geopolymer concrete incorporated with polypropylene (PP) fibers by Taguchi’s method. A three-factor three-level design experiments adopted three factors their corresponding levels alkali ratio (NaOH:Na2SiO3) (1:1.5 (8 M NaOH); 1:2 (10 1:2.5 (12 NaOH)), percentage GGBS (80%, 90%, 100%) PP (1.5%, 2%, 2.5%). M25 taken control mix gauging comparing results. Nine mixes were obtained using L9 orthogonal array, analysis performed. The revealed optimum molar) ratio, 80% GGBS, 2% workability; 2.5% strength; 1.5% strength. found be most effective parameter all responses. also ranks in terms significance determining ANOVA conducted on results validated reliability optimized further verified confirmation tests. tests quite close mix. Thus, comparable successfully achieved replacing thereby providing a better path development.
