Hair fibre reinforced concrete can be an effective method for the hair waste management. Many researchers prove that the addition of small, closely spaced, and uniformly dispersed fibers to concrete plays the role of cracker arrester and substantially enhance its static and dynamic properties. Fiber reinforced concrete has small distinct fibers that are homogeneously dispersed and oriented haphazardly. endstream endobj startxref 0000003679 00000 n He is a High-performance fiber-reinforced cementitious composites (HPFRCCs) are a group of fiber-reinforced cement-based composites which possess the unique ability to flex and self-strengthen before fracturing.

Fibre reinforced concrete (FRC) is a concrete containing fibres other than cement, sand and aggregates which increases the compressive strength, tensile strength and workability of concrete. Steel fibre reinforced concrete (SFRC) has been successfully used in various types of construction due to the fact that adding steel fibers improves the durability and mechanical properties of hardened concrete, notably flexural strength, toughness, impact strength, resistance Technical report (539 pages, ISBN 978-2-88394-142-7, August 2020) Besides the properties of fiber-reinforced concrete, the structural performance of the structures made of fiber-reinforced concrete was investigated and discussed in this special issue.
