Fiber matrix bond strength
WebIn steel fiber reinforced concrete, the interface is a very complex and weak structure. It is because of the weak interface layer between the steel fiber and the matrix that the reinforcing and toughening properties of the steel fiber cannot be fully exerted. The interface bond performance is the core of the meso-mechanical properties of steel fiber … WebNov 30, 2024 · The increased calcium silicate hydrate and contact area strengthened the bonding established between fiber and matrix, and the denser microstructure and …
