  • Abstract:
  • This study delves into the thorough performance assessment of lightweight concrete, enriched with industrial by-product fly ash and recycled aggregates across a spectrum of compositions. The integration of these alternative materials holds substantial promise for sustainable construction, aiming to mitigate environmental impacts and promote resource efficiency. The study begins by outlining the rationale for incorporating fly ash and recycled aggregates into lightweight concrete mixes, particularly for the purposes of enhancing mechanical properties while concurrently addressing environmental concerns. The research entails a systematic variation of fly ash content from 0% to 30%, alongside a constant 20% content of recycled aggregates as coarse aggregate. The concrete specimens formulated with these diverse compositions then undergo a battery of comprehensive tests, focusing on compressive, split tensile, and flexural strengths. These evaluations provide critical insights into load-bearing capacities, resistance to tension, and ability to withstand bending forces. The meticulous analysis of test results offers nuanced understanding regarding the impact of varying fly ash proportions on concrete performance. By specifically concentrating on compressive, split tensile, and flexural strength tests, the study provides valuable insights into how the combined influence of fly ash and recycled aggregates influences the concrete's mechanical behaviour. The outcomes highlight that the incorporation of fly ash within a certain range yields improvements in the lightweight concrete's mechanical properties. However, exceeding the optimal proportion of fly ash might lead to diminishing returns, potentially affecting overall strength. These findings guide the establishment of practical composition ranges, assisting engineers in formulating environmentally responsible concrete mixes that concurrently ensure structural performance. The significance of this research extends widely.
