Overview of Performance of Polysand Bricks in Construction Industry

The rising threat of plastic pollution and the urgent demand for sustainable construction materials have prompted researchers and industries alike to seek innovative solutions. One such approach is the transformation of waste plastics into construction bricks, known as plastic sand bricks or eco-bricks. This paper presents a comprehensive review of the existing literature and experimental studies that explore the feasibility, process, benefits, and challenges of using plastic waste in brick production. Drawing on multiple peer-reviewed articles and case studies, the review synthesizes findings on the mechanical performance, environmental implications, and economic viability of plastic bricks. The reviewed studies reveal that plastic bricks exhibit competitive compressive strength, reduced water absorption, improved durability, and cost-effectiveness compared to conventional clay bricks. They also highlight the environmental advantages of diverting plastic waste from landfills and incineration. However, limitations such as low fire resistance and structural constraints are also noted. This review affirms that plastic bricks hold substantial promise in sustainable construction, especially for non-load-bearing structures, and encourages further innovation and policy support to integrate them into mainstream building practices
