Concrete and plastic are a major source of environmental contamination and unsustainability. This study has been employed to come up with the eco-friendly concrete by using the plastic waste to promote the sustainability. Gamma radiations were used to enhance the micro-structure of plastic waste to increase the mechanical properties of resulting concrete. The crystallinity and chemical properties of regular and irradiated plastic were studied using x-ray diffraction (Xrd) and x-ray fluorescence (Xrf), respectively. Enhancement in the crystallinity and chemical properties were observed in the irradiated plastic. Different compositions by weight were opted for replacement of cement and fine aggregate for both regular and irradiated plastic waste with silica fume and superplasticizers. A set of experiments were performed on concrete and the effect of plastic waste on the compressive strength and split tensile strength of concrete was examined. Untreated replacement of plastic waste has shown to decrease the compressive strength and anomalous behavior was observed in case of split tensile strength. Both the mechanical properties were enhanced by replacing the cement and fine aggregates with irradiated plastic waste including silica fume and superplasticizers. This study contributes towards sustainable development of green concrete by lowering the carbon emissions and overcoming the fine aggregate scarcity problem. Moreover, as plastic is ductile and inclusion of plastic in concrete lowers the overall weight of the structure; impact of an earthquake is reduced.

混凝土和塑料是环境污染和不可持续性的主要来源。这项研究已被用来通过使用塑料废物来提高可持续性来开发环保混凝土。伽马辐射用于增强塑料废物的微观结构，以提高所得混凝土的机械性能。分别使用 X 射线衍射 (Xrd) 和 X 射线荧光 (Xrf) 研究了常规塑料和辐照塑料的结晶度和化学性质。在辐照塑料中观察到结晶度和化学性质的增强。选择不同重量的组合物来用硅粉和超增塑剂代替普通和辐照塑料废物的水泥和细骨料。对混凝土进行了一组实验，并检验了塑料废料对混凝土抗压强度和劈裂抗拉强度的影响。未经处理的塑料废料替代品已表明会降低抗压强度，并且在分裂抗拉强度的情况下观察到异常行为。通过用包括硅粉和超塑化剂在内的辐照塑料废物代替水泥和细骨料，这两种机械性能都得到了提高。本研究通过降低碳排放和克服细骨料稀缺问题，为绿色混凝土的可持续发展做出贡献。此外，由于塑料具有延展性，在混凝土中加入塑料可降低结构的整体重量；减少地震的影响。
