Here is the question of the month:<\/p>\n

Fibreglass reinforcement has many advantages: low weight, ease of installation, cost of transport and storage, corrosion resistance and many others. Is this the future of the industry? Is it already in use at AGF? <\/strong><\/p>\n

Fibreglass reinforcement does indeed have definite advantages such as those listed above.<\/p>\n

To this, we could also add its very high mechanical resistance! But its main advantage is resistance to corrosion, which alone is reason enough to encourage studies into its use in concrete structures. In fact, corrosion of rebar has been identified as the main cause of structural deterioration in North America! This is no exaggeration.<\/p>\n

However, there are currently a few reasons that stand in the way of its more widespread use. One of them is the lack of data on its durability, especially in alkaline environments. Some full-scale tests are underway, notably on the Jacques Cartier Bridge where AGF has installed a small section of fibreglass-reinforced slab. But to date, project engineers are still reluctant to use this product.<\/p>\n

There is also a more logistical reason, which has to do with its production and manufacturing.<\/p>\n

Fibreglass bars cannot be cold bent. Even hot bending is a challenge because it can only be done under certain conditions. In fact, most bends must be “molded” beforehand. This process does not allow the lengths to be adjusted to the part and therefore requires precise fabrication several weeks in advance. This is a major hurdle in the construction world, where speed and flexibility of execution are two essential qualities.<\/p>\n

But since the future is all about change and evolution, it will undoubtedly lead us to new operational solutions and new materials. And AGF will be at the forefront of these changes! In fact, we are participating in a study by the University of Moncton in New Brunswick on the development of fibreglass rods.<\/p>\n

Encontre aquí la pregunta del mes.<\/p>\n

La armadura de fibra de vidrio presenta muchas ventajas: peso ligero, facilidad de instalación, costo de transporte y almacenamiento, resistencia a la corrosión y muchas más. ¿Piensa que es el futuro del sector? ¿Ya la utilizó AGF?<\/strong><\/p>\n

La armadura de fibra de vidrio tiene, en efecto, beneficios claros como los enumerados en la pregunta. A esto podemos añadir que ¡su resistencia mecánica es muy elevada! Sin embargo, el beneficio principal es su resistencia a la corrosión, lo que representa en sí una razón suficiente para impulsar los estudios que requieran su utilización en estructuras de hormigón. De hecho, ¡la corrosión de las barras de acero de refuerzo fue identificada como la causa principal del deterioro de estructuras en Norteamérica! Lo cual significa mucho.<\/p>\n

Sin embargo, actualmente algunas razones frenan su uso más general. Una de ellas es la falta de datos sobre su durabilidad, en particular en medios alcalinos. Algunas pruebas a escala natural están en curso, específicamente el puente Jacques Cartier, en el que AGF instaló un pequeño tramo de losa con armadura de fibra de vidrio. No obstante, hasta el momento los ingenieros de los proyectos aún se muestran reticentes a utilizar este producto.<\/p>\n

También hay una razón más logística que se sitúa en su producción y su fabricación. En efecto, las barras de fibra de vidrio no pueden plegarse en frío. Incluso en caliente esto representa un desafío ya que esto puede realizarse solamente en determinadas condiciones. De hecho, la mayoría de los pliegues deben ser moldeados previamente. Este proceso no permite ajustar las longitudes a la pieza y por lo tanto implica una fabricación precisa con varias semanas de anticipación. Esto representa un obstáculo importante en el mundo de la construcción, en el que la rapidez y la flexibilidad de ejecución son dos atributos esenciales.<\/p>\n

No obstante, el futuro siempre cambiante y en evolución nos llevará seguramente hacia soluciones operativas y nuevos materiales. Y AGF ¡se encontrará a la vanguardia de estos cambios! De hecho, participamos en un estudio de la Universidad de Moncton en Nuevo Brunswick que se centra en el desarrollo de varillas de fibra de vidrio.<\/p>\n
