Advanced exploration of current state-of-the-art of practices of fiber-reinforced self-compacting geopolymer concrete Untersuchung zum aktuellen Stand der Technik von Praktiken von faserverstärktem, selbstverdichtendem Geopolymerbeton

Abstract

Cement industries, pivotal in concrete production, remain a global environmental concern due to their impact on sustainability. Traditional concrete exhibits robust compressive strength but lacks in tension strength, often resulting in cracks. Addressing this, well-dispersed fibers play a crucial role in mitigating crack formation. Reinforcement strategies, transferring tensile loads to the material, are pivotal for enhancing concrete's overall strength. Geopolymers emerge as a sustainable alternative, potentially reducing greenhouse gas emissions associated with cement production. With the prospect of replacing Portland cement, geopolymers, including fly ash, ground granulated blast furnace slag, and silica fumes, aim to minimize carbon footprints. This research optimizes the workability and mechanical properties of self-compacting geopolymer concrete by adjusting binding materials, molarity, superplasticizer, curing temperature, and fibers. Concrete alternatives like self compacting geopolymer concrete are resource- and waste-efficient since they compress under their own weight. Composite geopolymers with fiber reinforcing are widespread. Microstructural, mechanical, and physical qualities are explored in fiber reinforced geopolymer concrete research publications by fiber type. Self-compacting geopolymer concrete is more environmentally friendly and resource-efficient than ordinary concrete, according to this study. Geopolymer composites are improved by studying fiber reinforced self compacting geopolymer concrete with different fiber reinforcements.
