This research uses Escherichia coli bacteria as the model bacteria to assess the efficacy of adding CuO nanoparticles as an antibacterial agent to Portland cement. The disc diffusion technique is used to assess antibacterial characteristics. Where in humid environmental conditions can trigger health problems in the community in the neighborhood where they live. CuO was added to Portland Cement at different rates of 0%, 1%, 3%, and 5% (%w/w) to conduct the assessment. To achieve a perfect dispersion, the nanoparticles were then combined with water using an ultrasonic mixer before being added to the cement. Additionally, characterisation was performed using XRD in order to establish the size of the CuO nanoparticles and the type of crystal that was generated. SEM was used for morphological investigation and characterisation oof Cement-CuO. The ensuing clear zone, which shows the region where bacterial growth was inhibited, serves as a visual indicator of antibacterial efficacy. The results showed that to produce the best antibacterial effectiveness is with a variation in the addition of CuO as much as 3% which results in a size of 7 mm in the diameter of the inhibitory zone. The presence of resistance power indicates that the resulting antibacterial cement shows an effect on the growth of Escherichia coli bacteria. © 2024 American Institute of Physics Inc..
