Partial replacement of cement by glass powder and fine aggregate by plastic pellets

Abstract

The integration of alternative materials like plastic pellets and glass powder into concrete has gained attention due to environmental concerns and the pursuit of sustainable construction practices. This abstract delves into the potential benefits and challenges associated with incorporating these materials into concrete mixtures. Plastic pellets, derived from recycled plastics, offer a viable solution to reduce plastic waste while enhancing the properties of concrete. Their inclusion can improve the workability, durability, and reduce the density of concrete. Moreover, plastic pellets serve as an alternative to conventional aggregates, thereby conserving natural resources and reducing carbon emissions associated with traditional concrete production. Similarly, glass powder, obtained from waste glass, presents an environmentally friendly option for enhancing concrete properties. Its incorporation can improve the compressive strength, reduce permeability, and enhance the durability of concrete. Additionally, the use of glass powder aids in reducing the consumption of raw materials and energy during concrete manufacturing processes. However, challenges such as proper dosage, compatibility with other concrete constituents, and potential adverse effects on long-term performance need to be addressed when incorporating plastic pellets and glass powder into concrete mixtures. Furthermore, the economic feasibility and scalability of production and implementation must be considered to ensure widespread adoption of these sustainable practices.
