La misión principal del pretensado circunferencial de la pared de un depósito cilíndrico de hormigón es la de compensar las atracciones anulares originadas por la carga de agua y, en menor medida, contrarrestar las debidas ...

Los Hormigones Reforzados con Fibras (HRF) constituyen una de las innovaciones más relevantes en el campo de los hormigones especiales. La presencia del refuerzo provoca una sustancial modificación de la respuesta mecánica ...

From immemorial time, dams have contributed significantly for the progress of civilizations. For this reason, nowadays, there is a vast engineering heritage. Over the years, these infrastructures can present some ordinary ...

There are many advantages when using FRC in the manufacturing of segmental linings of tunnels built by means of a Tunnel Boring Machine (TBM). The use of steel fibre reinforced concrete (SFRC) improves, on the one hand, ...

This paper presents an experimental campaign in which concrete pipes were manufactured using plastic fibres as the sole reinforcement material. In this regard, it has been demonstrated that the use of plastic fibres is ...

The high-performance demands on industrial floors, both in terms of larger slab dimensions and increased durability under harsh operating conditions, have led to the growing use of expansive admixtures. These generate a ...

La determininación del módulo de elasticidad del hormigón de presas es difiícil tanto en medidas directas en la presa como mediante probetas, ya que se requieren ensayos con probetas de gran dimensión y, consecuentemente, ...

Biodeterioration of concrete by microorganism colonisation may be a problem in several structures, especially in irrigation and hydroelectric canals. The main problem in such structures is the proliferation of algae and ...

Conductive cementitious materials have gained immense attention in recent years owing to the possibility of achieving multifunctional materials. The usual approach has been to incorporate carbonaceous nanomaterials and/or ...

The objective of this paper is to propose a novel numerical approach to evaluate the fresh state behavior of pervious concrete (PC). A new constitutive law applied to Discrete Element Method was developed for the simulation ...
