Thermal distribution of paver block with machine learning optimized design with alternative eco-friendly materials
摘要
The integration of fly ash and addition of coconut fibre into paver blocks offers a unique and recyclable approach to enhancing thermal insulation in urban infrastructure. Fly ash, a byproduct of coal combustion, lower the density of the paver block, leading to enhanced thermal conductivity and cooler surface temperatures. The natural fibrous structure of coconut fibre generates air spaces within the material, serving as heat barriers and enhancing thermal resistance. This combination minimises heat transfer and contributes to improving the urban heat island effect, thereby reducing the reliance on energy-demanding cooling systems in nearby structures. The application of these renewable resources improves the thermal efficiency of paver blocks while promoting sustainability using waste products and the reduction of carbon emissions. Response Surface Methodology (RSM) results indicated that the R2 value for the compressive strength was 0.9655. The results of this investigation indicate a compressive strength of 39 N/mm2 achieved with the M1 mix ratio. This study investigates the thermal characteristics and energy-saving capabilities of these improved paver blocks, showcasing their efficiency in lowering surface temperatures and enhancing energy conservation in warm climates. The results demonstrate that the incorporation of fly ash and coconut fibre into paver blocks presents a promising approach for eco-friendly building practices and energy savings.
