Sustainable Construction Revolution: Fly Ash as Artificial Fine Aggregate and Fiber Glass as Innovative Additive in Lightweight Concrete

Abstract

The paradigm of sustainable construction is undergoing a revolutionary transformation with the integration of novel materials. This study explores the use of fly ash as an artificial fine aggregate and fiber glass as an innovative additive in the formulation of lightweight concrete. The research aims to enhance the sustainability of construction practices by reducing the environmental impact associated with traditional concrete production. The final compressive strength and absorption tests were conducted, and the results were compared with those of conventional lightweight concrete. The collected data will undergo analysis to ascertain the strength of lightweight concrete across various content ratios while maintaining consistent size. As a result of various compositions, the concrete revealed different properties. The density ranged from 1804 to 2070 kg/m3, and the corresponding strength ranged from 13.5 to 29.6 MPa. The durability research results of tested lightweight concretes showed that, despite considerably higher water absorption, a comparable water permeability and comparable or better freeze-thaw resistance in relation to normal-weight concrete may be present. Through a series of experiments and analyses, the study investigates the mechanical properties, durability, and environmental benefits of the developed lightweight concrete. The findings reveal a synergistic effect between fly ash and fiber glass, resulting in a lightweight concrete that not only exhibits improved performance but also contributes to the overall sustainability goals of the construction industry. This abstract provides a glimpse into the transformative potential of adopting fly ash and fiber glass in lightweight concrete, paving the way for a more eco-friendly and resilient future in construction.
