Experimental Study on Bending Performance of High-Performance Fiber-Reinforced Cement Composite Prefabricated Monolithic Composite Beams

To enhance the mechanical properties and damage resistance of prefabricated monolithic composite beams, this study introduces HPFRCC precast mold shells as a replacement for ordinary concrete in construction beams. These shell beam members are then subjected to experimental investigations analyze their flexural properties. The results indicate that U–shaped exhibits excellent bonding with post-cast concrete, no significant peeling observed. Moreover, compared cast-in-place RC HPFRCC/RC beams demonstrate 17.2% increase peak load 24.55% yield load. Similarly, show an 8.1% 5.59% In comparison both cracks observed denser finer, smaller crack development rate width. findings suggest incorporation materials improves members.
