Abstract The objective of this study is to comprehensively investigate the influence incorporating high-density polyethylene (HDPE) waste plastic on thermophysical properties ordinary concrete, by partially replacing sand with HDPE powder. samples (cement, sand, HDPE, and concrete) were characterized using advanced analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence (XRF). These analyses confirmed that incorporation powder does not induce significant alterations in internal microstructure composite material. Thermophysical measured a CT-Meter for various substitution rates (5–30% weight) at different temperatures (25°C, 30°C, 40°C, 50°C) thermoregulated box. results demonstrated progressive decrease thermal conductivity diffusivity increasing content. Furthermore, volumetric heat capacity increased as 5% was added, then decreased. This phenomenon observed all analysed, except 25°C. Moreover, into concrete significantly altered its properties, leading reduction performance.
