Strengthening of the concrete face slabs of dams using sprayable strain-hardening fiber-reinforced cementitious

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 2,   Pages 145-160 doi: 10.1007/s11709-022-0806-4

Abstract: strain-hardening fiber-reinforced cementitious composites (FRCC) were applied to strengthen the concrete slabsanalytical investigations were carried out to understand the flexural properties of FRCC-layered concrete slabsIt was found that the FRCC layer improved the flexural performance of concrete slabs significantly.a simplified analytical method were developed for the design and analysis of FRCC-layered concrete slabs
