Enhancing Sustainability in Construction: An Evaluation of Lightweight Concrete with Sintered Fly Ash and Waste Marble Sand
Marble waste and fly ash are industrial waste, and disposal of these wastes is a big challenge for environmental sustainability. In this study, we explore an innovative approach to sustainable construction by utilizing industrial by-products: sintered fly ash aggregate (SFA) and waste marble sand in lightweight aggregate concrete (LWAC). This study used SFA as a coarse aggregate, whereas river sand was partially replaced by waste marble sand (10–50 %). The waste marble sand modified LWAC has been investigated for mechanical and durability properties. The test related to permeability like water absorption, sorptivity, permeability, and drying shrinkage has been performed. Mercury intrusion porosimetry test was performed to validate durability results. The results indicate that 30 % of river sand can be replaced with waste marble sand as it improves the overall performance of LWAC. Our research contributes to global sustainability efforts by providing a method to reduce industrial waste through its incorporation in building materials. This study not only addresses the urgent need for environmental preservation but also offers potential enhancements in the mechanical properties of LWAC, making it a viable and eco-friendly option in the construction industry worldwide.
期刊介绍：
The journal is published continuously in one annual issue online. Papers are published online as they are approved and edited. Special Issues may also be published on specific topics of interest to our readers. Advances in Civil Engineering Materials provides high-quality, papers on a broad range of topics relating to the properties and performance of civil engineering materials. Materials Covered: (but not limited to) Concrete, Asphalt, Steel, Polymers and polymeric composites, Wood, Other materials used in civil engineering applications (for example, pavements, bridges, and buildings, including nonstructural building elements such as insulation and roofing), and environmental systems (including water treatment). Core Topics Covered: Characterization, such as chemical composition, nanostructure, and microstructure, Physical properties, such as strength, stiffness, and fracture behavior, Constructability, such as construction methods, quality control/assurance, life cycle analysis, and sustainability, Durability. Papers may present experimental or modeling studies based on laboratory or field observations. Papers relating to sustainability of engineering materials or to the impact of materials on sustainability of engineering structures are especially encouraged.
