Structural Concrete, EarlyView.Abstract Lightweight strain‐hardening ultra‐high‐performance concrete composite (SH‐UHPC) is an outstanding alternative for engineering applications and infrastructure thanks to its outstanding strength, toughness, ductility, and low density. The integration of artificial intelligence (AI)‐based modeling strategies into engineering problems can ...

Structural Concrete, EarlyView.Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

MECHANICAL PROPERTIES OF HYBRID FIBER REINFORCED CONCRETE FOR PAVEMENTS
International Journal of Research in Engineering and Technology, 2013 The effect of addition of mono fibers and hybrid fi bers on the mechanical properties of concrete mixtu re is studied in the present investigation. Steel fibers of 1% and polypropylene fibers 0.036% were added individually to the concr ete mixture as mono fibers and then they were added together to form a hybrid fibe r reinforced concrete.

Rotation capacity of continuous reinforced concrete slab strips revisited
Structural Concrete, EarlyView.Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

The challenges of GFRP RC beam design for limit states
Structural Concrete, EarlyView.Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Determination of mechanical properties of hybrid fiber reinforced concrete
, 2004 Fiber reinforcement is commonly used to provide toughness and ductility to brittle cementitious matrices. Reinforcement of concrete with a single type of fiber may improve the desired properties to a limited level. A composite is termed as hybrid, if two
