Strengthening of Reinforced Concrete Beams with Ultra-high Performance Fiber-Reinforced Concrete in Shear

Ultra-high performance fiber-reinforced concrete (UHPFRC) exhibits high compressive and tensile strength together with outstanding durability. Due to these superior properties, UHPFRC is promising for retrofitting existing reinforced concrete (RC) bridges. While research and on-site applications show the significant improvement of RC structures...

Effect of freeze-thaw cycles on shear resistance of reinforced concrete beams strengthened with UHPFRC

Ultra-high performance fiber-reinforced concrete (UHPFRC) has emerged as one of the promising materials for strengthening of concrete structures. For the strengthening application of UHPFRC, one of the primary concerns is to evaluate the degradation of bond behavior and structural re-sponse of strengthened elements under harsh environmental...

Strain hardening cementitious composite (SHCC) layer for the crack width control in reinforced concrete beam

Strain Hardening Cementitious Composite (SHCC) is an innovative material which, due to the special material composition and the addition of fibres, exhibits a controlled microcracking behaviour under tensile stresses. As such it might be a promising material for improvement of durability of concrete structures.<br/>An experimental study was...
