A review of Enhancing Abrasion Resistance of Dry Geopolymer Ramie Fiber Composite Mortar in Hydraulic Structures

Abstract

Abstract Hydraulic structures, such as dams, spillways, and tunnels, suffer from severe abrasion and erosion due to the continuous flow of water and particles carried away. Such damage will result in expensive operating and maintenance of hydraulic structures. The purpose of this review is to discuss various abrasion testing methods as well as various efforts enhancing abrasion resistance, such as adding silica fume, and fibers, improving quality, and using geopolymers. In conclusion, the development of dry geopolymer methods offers great potential for use because they are more practical than wet geopolymer systems, however, the brittle nature of geopolymers is a weak point, which can be addressed by adding composite materials, such as ramie fiber. With the expectation that the matrix of composite geopolymer mortar with ramie fiber will have good abrasion resistance. Further research and development are needed to address existing challenges and establish this innovative construction material as a viable solution for sustainable hydraulic applications.
