This article intends to study the influence of metal fibers on the behavior of concrete exposed to aggressive media. The main contribution of the experimental work proposed here lies in the detailed monitoring of the concrete degradation process as a function of fiber deterioration. To do this, fiber-reinforced and non-fiber-reinforced concretes we...

Recently, the technique of placing concrete by pumping has become very popular because it offers users many advantages. However, it must be recognized that during the pumping operation, the concrete can become blocked inside the pipes if it does not meet certain workability and uniformity criteria. For this, the characteristics of the concrete to b...

A large number of recent studies have shown that the tribological parameters of concrete, such as the interface yield stress and viscous constant, which both essentially depend on formulation, are sufficient for the characterization of its pumpability and the prediction of problems associated with concrete pumping. The current environmental conside...

Mortar is the mixture of paste or mud, binder and aggregates with water. It is used in masonry as a bonding element, sealing element or as a coating. Technically speaking, it's a glue. The shift in mentality and technology is to integrate natural products into the manufacture of cementitious materials to promote sustainable development. It is in th...

Concrete is the most widely used material in all areas of construction and building, despite its complexity. It usually contains a mixture of cement, water and aggregates, but it is considered homogeneous. Not only can it be molded into the most diverse shapes (dome, vault and elements with complicated shapes), but also excellent compressive streng...

La durabilité des structures en béton est l’un des facteurs importants qui intéresse une large communauté de scientifiques dans le domaine du génie civil. Cette dernière est influencée par l’environnement extérieur (gel, dégel, pluie….). Ces influences deviennent plus importantes quand nous devons garantir la durée de service de la structure sur un...

Concrete leaching is a phenomenon that can cause significant damage to structures and significantly affect their durability. Some experimental and numerical research carried out these last year’s made it possible to understand the mechanism at the origin of this degradation. However, with the use of new ecological materials in the concrete formulat...
