Residual strength and microstructure of fiber reinforced self-compacting concrete exposed to high temperatures

Application of Ultrasonic Measurements for the Evaluation of Steel Fiber Reinforced Concrete

“…It is important to recognize that, in general, fiber reinforcement is not a substitute for conventional reinforcement [24]. The addition of steel fibers in concrete can improve its toughness [14,[25][26][27][28][29][30][31][32][33][34][35][36][37][38], ductility, and post-crack resistance [29].…”

“…Self-Compacted Concrete (SCC) [30] is the concrete which is allowed to compact with its own weight without applying any vibrational effort. The reason for selecting SCC is to avoid steel fiber and aggregate segregation and bleeding.…”

Comportamiento Térmico y Estructural del Concreto Expuesto a Altas Temperaturas: Una Revisión de la Literatura

“…La pérdida de resistencia a la compresión de muestras de concreto hasta 200°C es casi insignificante, pero será del 40% y 64% cuando la temperatura aumenta en 400°C y 600° C, respectivamente (Sadrmomtazi et al, 2020 Los hormigones con f'c de 25, 35 y 40MPa mostraron pérdida de resistencia tras el enfriamiento brusco. El hormigón con f'c 25 MPa tuvo una reducción de la resistencia proporcional al aumento de temperatura, mientras que los otros hormigones mostraron una reducción de la resistencia más gradual y logarítmica (Coelho et al, 2020).…”

Crack Detection and Localisation in Steel-Fibre-Reinforced Self-Compacting Concrete Using Triaxial Accelerometers

“…Over the past decade, extensive research has been conducted on SFRSCC in terms of its workability, mechanical properties, and structural performance with increasing usage in the construction industry [ 14 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Its usage expands to both non-structural and structural applications, such as industrial floors, roads and pavements, sprayed concrete, overlays, composite slabs on steel decking, tunnel lining segments, and precast elements [ 28 ].…”
