| Abstract | This research uses the Responses Surface Method (RSM) approach to make and optimize environmentally friendly bricks using a PET and epoxy resin mixture. The main input factors for the mixture are PET particles and epoxy resin as adhesive materials, while compressive strength is the primary response of the sustainable brick produced. RSM-based Central Composite Design (CCD) was used to assess the influence of PET particle variables (1-5mm) and epoxy resin ratio (30-50%) on the compressive strength response. The accuracy of the mathematical model created by CCD was tested using ANOVA. The RSM evaluation results show that the empirical findings suit linear and quadratic models for cost response and compressive strength. A coefficient of determination greater than 0.85 for all reactions indicates that the model can explain response variability. The optimization results show that the input variables PET particle and epoxy resin ratio have an average optimum value of 40% epoxy resin, each with a PET size of 3 mm. This optimal combination produces a maximum compressive strength of 13.37 MPa. The study and application of a mixture of PET particles and epoxy resin in making sustainable bricks has shown that these materials have great potential to increase the compressive strength of sustainable bricks. |
