Experimental Study of the Performance of Two-way RC Slabs Retrofitted with High Performance Fibre Reinforced Cement Composite (HPFRCC) prefabricated laminates

Reinforced concrete structures need to be strengthened and retrofitted for various reasons, including errors during design and/or construction, and in most cases reinforcement of structural elements is much more economical than rebuilding the structure. Using HPFRCC with tensile stiffening behaviour...
