Study on The Effect of Human Hair Content on The Properties of Cement Concrete

Abstract

In the modern era, waste recycling and environmental pollution reduction are the primary objectives of sustainable development. To achieve this goal, this study utilizes human hair fibers, an abundantly available waste material, to enhance the properties of concrete. The research evaluates the effects of human hair fibers on concrete properties by incorporating different fiber-to-cement weight ratios of 0.25%, 0.50%, and 1.0%. The concrete properties examined in this study include workability (slump), compressive strength, and flexural tensile strength of standard specimens cast from concrete mixtures with varying human hair fiber content after a curing period of 28 days. Experimental results indicate that the workability (slump) of the concrete mixture containing human hair fibers tends to decrease as the fiber content increases. However, human hair fibers function similarly to conventional fiber-reinforced concrete, improving compressive strength and flexural tensile strength by 10.99% and 17,91%, respectively, at fiber-to-cement ratios of 0.25% and 1%.
