This paper investigates increasing polymer addition into ordinary cement mortar (OCM) composites. The main areas of study include material fabrication, workability, mechanical properties, durability, microstructure, and application of OCM composite materials. This paper introduces the application of PMCM and discusses the prospects and challenges of PMCM composite materials. In this work, we examine the impact of waste Ethylene Vinyl Acetate (EVA) and Polyethylene Terephthalate (PET) on cement-based mortar's mechanical characteristics and workability. Variations of 0.2%, 0.5%, 0.8%, 1.1%, and 1.4% of the PET polymer are employed in place of sand. In the meanwhile, variants of 2%, 4%, 6%, 8%, and 10% of the EVA polymer are used as Portland cement substitutes. Immersion techniques were used to create the polymer mortar for 7, 14, 21, and 28 days. The study's findings show that when the amount of polymer in a mortar increases, its compressive strength falls. The polymer mortar's compressive strength value, however, revealed the best outcomes after 28 days of immersion. The results of XRF characterization data, SiO2 and CaO are the most common components in polymer mortar. Calcite, quartz, corundum, and hematite are the most prevalent phases. Results of SEM-EDS analysis display the polymer mortar's shape as well as the elements that were found, which include O, C, Ca, Si, Al, Fe, S, and Mg. Results from the FTIR characterization show wavelengths in the polymer mortar that correspond to the presence of functional groups such C-O, Si-O-Si, Si-O, and O-H. © 2025, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.
