Monitoring the reduction in shrinkage cracking of mortars containing superabsorbent polymers [PDF]
Ultra-high performance concrete (UHPC) is characterized by a low water-to-cement ratio, leading to improved durability and mechanical properties. However, the risk for autogenous shrinkage and cracking due to restrained shrinkage increases, which may ...

Tensile Performance of Prefabricated Tank Walls Connected Using Ultrahigh‐Performance Concrete
Prefabricated tank structures are a widely used form of industrialized construction, yet the behavior of connections between precast segments remains insufficiently explored. Since the mechanical properties of these connections govern the structural performance of prefabricated tanks, this study introduces a novel joint detail employing cast‐in‐place ...

Experimental Study of a Novel Type Joint Used in Precast Reinforced Concrete Frame Under Reversals
Prefabricated components are an integral part of the prefabricated construction. One of the main challenges in seismic regions is developing constructible connections between prefabricated components that can withstand inelastic cyclic deformations. This study introduces a novel type of joint designed to connect prefabricated concrete columns and beams
