Long-Term Properties of Different Fiber Reinforcement Effect on Fly Ash-Based Geopolymer Composite

Geopolymer composites have been around only for 40 years. Nowadays, they are used in buildings and infrastructures of various kinds. A geopolymer’s main benefit is that it a green material partially made by utilizing waste products. The carbon footprint from geopolymer matrix manufacturing at least two times less than Portland cement manufacturing. Due to the nature process, there high risk shrinkage could develop unwanted micro-cracks reduce strength create higher creep strains. Because this concern, common strategy long-term strains material, such as creep, add fiber reinforcement would constrain crack development material. This article aims determine how kinds amounts different affect fly ash-based composites’ compression. Specimen mixes were produced with 1% steel fibers, polypropylene 5% without fibers (plain geopolymer). For testing, cylindrical specimens Ø46 × 190 mm used. highest resistance was observed specimens, followed fiber, plain, specimens. compressive plain fiber-reinforced mix improved properties inclusion, whereas other fiber-introduced showed significant decreases properties. composite reduction 31% compared composite.
