Лидирующее место в достижениях в области строительства занимает 3D-печать, которая позволяет создавать прочные и сложные конструкции, минимизируя потери ресурсов. В качестве жизнеспособной замены обычным цементным материалам выделяют экологические преимущества и высокие механические характеристики геополимеров на основе летучей золы. Это исследование изучает, как добавление полиэтиленовых (PE) волокон изменяет эти свойства и как различные концентрации влияют на поведение текучести и способность производства композитного материала. Анализ неньютоновского поведения в этих материалах проводится с использованием модели Гершеля-Балкли. Точно измеряя критические реологические факторы, такие как вязкость и поведение потока, это исследование оценивает, как эти факторы влияют на процессы 3D-печати. Оптимальное сочетание содержания волокон выявляется в контролируемых испытаниях, которые сочетают в себе управляемый поток экструзии и надежностью конструкции. Результаты предлагают практические применение, раскрывают методы производства геополимеров, способных поддерживать прочность, соответствуя строгим требованиям методов 3D-печати.

The leading edge of construction advancements is represented by 3D printing which creates durable and elaborate structures and minimizes resource wastage. As a viable substitute for regular cement materials highlights the ecological benefits and strong mechanical traits of fly ash geopolymers. This study investigates how the addition of polyethylene (PE) fibers alters these properties and how varying concentrations influence the flow behavior and capability of producing the composite material. The analysis of non-Newtonian behavior in these fiber-reinforced geopolymers is conducted using the Herschel-Bulkley model. By precisely measuring critical rheological factors  such as viscosity and flow behavior researchers can evaluate how they influence 3D printing processes. This research reveals that adding PE fibers boosts the material’s strength and improves resistance against cracking while also elevating the viscosity and yield stress that can hinder its passage through the printer’s nozzle. An optimal blend of fiber content emerges from controlled tests that align increased durability with controllable extrusion flow and structure reliability. The results offer deep practical applications that reveal methods for producing geopolymers that can maintain strength while meeting the exacting requirements of 3D printing methods. Research deepens the grasp of how adding fibers alters the properties of geopolymers and enriches the overall dialogue on green building materials. It opens doors for subsequent analysis of complex fiber systems and creative additive practices to boost the effectiveness and resilience of construction materials in practical use.
