Literature Review on Overcoming Graphene Dispersion Challenges in Ultra High Performance Concrete: A Review of Self-Dispersion and Bio-Polymer Encapsulation Strategies
Abstract: Abstract—Ultra-High-Performance Concrete (UHPC) is a new generation of cement-based material because of its higher compressive and tensile strength, increased durability, and higher resistance to environmental degradation. However, UHPC undergoes microcracking when subjected to mechanical and thermal loading, which can jeopardize the long-term performance of the structure, decrease service life, and cause expensive maintenance. Traditional solutions to enhance UHPC durability are centered on material densification and fiber strengthening, while these treatments …
