Experimental Study on Concrete Reinforced with Human and Horse Hair Fibers

In 2020, a study was conducted by Zakaria Hameed Awadallah Ibrahim to investigate the mechanical properties of concrete reinforced with human and horse hair fibers. The research aimed to improve the tensile properties of concrete, a material known for its brittleness, by using hair fibers, a cheap and abundant non-degradable material. The experiments involved concrete cylinders, cubes, and prisms with varying percentages of human and horse hair fibers (0%, 1%, 1.5%, and 2.5% by weight of cement) and two grades of reference plain concrete (20 and 40 MPa). The results indicated an increase in various mechanical properties and strength of concrete with the addition of human and horse hairs.
