Fitting the fracture curve of concrete as a density function pertaining to the generalized extreme value family
(Elsevier, 2017-09)
The load-displacement (P-δ) curve, recorded during the fracture process of concrete in three-point bending tests, is supposed to depict a fracture phenomenon of statistical character that can be suitably described by a ...

Multiscale Analysis of the Influence of Steel Fiber Reinforcement on the Shear Strength of Post-Tensioned Dry Joints
(MDPI, 2020-08)
In this work we follow a multiscale methodology to characterize the structural performance of post-tensioned steel fiber-reinforced concrete dry joints. At the material level, we use an experimentally validated ...

Probabilistic Flexural Fatigue in Plain and Fiber-Reinforced Concrete
(MDPI AG, 2017-07)
The objective of this work is two-fold. First, we attempt to fit the experimental data on the flexural fatigue of plain and fiber-reinforced concrete with a probabilistic model (Saucedo, Yu, Medeiros, Zhang and Ruiz, Int. ...

Determinación de la relación momento-curvatura en vigas de hormigón armado reforzados con fibra de carbono
(Asociación española de ingeniería mecánica, 2004)
En los últimos años, el aumento de los refuerzos de elementos estructurales de hormigón armado con fibra de carbono ha sido considerable. La fisuración en este tipo de elementos reforzados, se observa que es diferente a ...

Analysis of the Utilization of Air-Cooled Blast Furnace Slag as Industrial Waste Aggregates in Self-Compacting Concrete
(MDPI, 2019-03)
In this work, the effects of replacing the aggregates of self-compacting concrete by air-cooled blast furnace slag have been analysed. Different mixes have been manufactured by substituting the fine and coarse natural ...

Experimental study of a noise reducing barrier made of fly ash
(CSIC Consejo Superior de Investigaciones Científicas, 2021)
Although fly ash is commonly used as an additive to cement, large amounts of this material are disposed in landfills. To mitigate, it would be interesting to develop new products in which fly ash can be easily used and ...

Effect of mix design on the size-independent fracture energy of normal- and high-strength self-compacting concrete
(Consejo Superior de Investigaciones Científicas (CSIC), 2018-02)
Self-compacting concrete has a characteristic microstructure inherent to its specific composition. The higher content of fine particles in self-compacting concrete relative to the equivalent vibrated concrete produces a ...

Comparison of fracture toughness values of normal and high strength concrete determined by three point bend and modified disk-shaped compact tension specimens
(Gruppo Italiano Frattura, 2017)
The modified disk shaped compact tension test is a configuration derived from standard compact tension test that is used for measuring fracture mechanical properties of primarily metallic materials. The compact ...
