Advancements in Fiber-Reinforced Geopolymer Along with 3D Printed and Nano Concrete in Sustainable Construction (2025-08)¶

The mechanical and durability performance of innovative sustainable concrete technologies more especially, fiber-reinforced concrete (FRC), geopolymer reinforced concrete (GRC), 3D printed reinforced concrete (3DRC), and nano-based concrete (NBC) is investigated here. The intention is to assess and contrast these materials in relation to contemporary building requirements and environmental sustainability. Examining more than 100 peer-reviewed papers from Scopus and Web of Science databases using a combined qualitative and quantitative approach, Using kernel density plots, Q-Q graphs, and Weibull analysis, key mechanical parameters including compressive strength, elastic modulus, Poisson’s ratio, and fracture toughness were statistically tested. Achieving compressive strengths of 60–95 MPa, elastic moduli between 30 and 42 GPa, and exceptional crack resistance, the results show that nano-based geopolymer concrete routinely beats others. Between 3 % and 5 % was found to be the ideal fiber content; 25–40 mm fiber lengths enhanced mechanical integrity. Particularly Goal 9 (Industry, Innovation, and Infrastructure) and Goal 13 (Climate Action), these results fit the United Nations Sustainable Development Goals. The work emphasizes the pragmatic benefits of using geopolymers and nano-enhanced materials in the building of sustainable infrastructure.
