NANOPARTICLE REINFORCEMENT OF FERROUS ALLOYS: WETTABILITY AND MECHANICAL PROPERTIES

El refuerzo de matrices férricascon una fina dispersión de partículas nanométricas permite mejorar la dureza, resistencia mecánica e incluso permitiría mejorar la tenacidad del material al afinar el tamaño de grano.

Optimization study of the structural HACFRA composition (Self Compacting Concrete Steel Fiber Reinforced)

The interest of HACFRA (self compacting concrete reinforced with steel fibers), is the combination of the residual strength increase and cracking decrease compared to plain concrete by the introduction of steel fibers in the mass with the advantages of the self-compacting. The paper presents an analysis of the influence of different components of the HACRFA and provides their selection, refered to the granular skeleton and to different steel fiber types and amount, in order to obtain an optimization of its features and structural behavior.
