Due to high tensile strength and high friction coefficient, human hair has been used for reinforcing clay-based constructions. In rural areas in Uttar Pradesh and Madhya Pradesh, India (author’s field discussions, [30]), Bangladesh [31], Syria [32], and in European countries [33], human hair/clay mixture (along with other binders) is used in plastering house walls, lining ovens, making wheels, and so forth. The addition of hair significantly reduces cracking and prolongs the life of these structures. Research shows that human hair reinforcement enhances the structural strength as well as the thermal insulation capacity of the clay structures [34, 35]. Although such clay-based constructions are now decreasing in rural areas, they are gaining importance in sustainable architecture.
Human hair reinforcement also reduces cracks in cement mortar caused by plastic shrinkage by as much as 92% [36] and increases the compressive strength of fly ash/cement concrete by over three times [37]. This improved fracture-resilience and strength of hair-reinforced cement and fly ash concrete is highly useful in high-pressure-bearing structures such as petroleum wells and bridges. Any kind of hair can be used in these applications.
