A dramatic increase in the manufacturing and usage of single-use, disposable face masks has been seen during the COVID-19 epidemic. By failing to properly dispose of worn face masks, a new type of nonbiodegradable plastic trash that will take hundreds of years to decompose endangers the environment. Therefore, there is a pressing need to recycle such garbage in a way that is ecologically benign. This study offers an effective method for producing cost-effective, green concrete that is ecologically beneficial by using waste masks that have been crushed or fibered. This study evaluated the mechanical and robustness characteristics of waste masks made using concrete. For standardized testing to assess compressive strength quick chloride penetration test, a total of six mixtures were created (RCPT),. While crushed masks were only utilized at 0.5%, the percentages of mask fibres used were 0.5, 1, 1.5, and 2% of concrete by volume. Both kinds of the mask waste were determined to be appropriate for use in concrete. It was discovered that 1% of waste mask fibres was the ideal amount to improve compressive strength and decrease chloride permeability. In addition, 0.5% crushed mask fibre also worked well, particularly when creating concrete that is more resistant and less permeable. Thus, it is confirmed that waste masks that worsen global pollution may be used responsibly to support the construction of green buildings. Circular economy, sustainability, and effective waste management are achieved by recycling discarded masks to create new concrete with greater strengths and durability.
