This study investigates the use of recyclable waste materials such as glass powder (GP), glass fiber (GF), and human hair (HH) to enhance the mechanical performance and sustainability of M-30 grade concrete. Concrete mixes were prepared by partially replacing of fine aggregate with glass powder and incorporating glass fibers and human hair at prearranged dosages. Workability and compressive strength were tested at 7, 14 and 28 days. Results indicate that all mixes achieved more than 60% of their 28-day strength at 7 days, with the experimental mixes demonstrating modest improvements in early and ultimate compressive strength. The optimal mix achieved a 28-day compressive strength of 32.21 N/mm². The findings suggest that these recyclable materials can be employed to improve performance while promoting environmental sustainability.
