Concrete Construction Industry in the face of durability challenges

The rapid change in social and economic contexts, accompanied by an equally rapid evolution of climatic and environmental conditions, makes the problems of durability of the existing and newly built infrastructural heritage central .

In this context, concrete plays a fundamental role not only with reference to its dominant presence in the built environment but also due to the new potential, in terms of materials, products, constructive concepts, that the technology of concrete and cement materials is capable of. to offer thanks to its latest developments.

ReSHEALience Workshop Endurcrete at Made Expo
The event scheduled for Thursday 14 March at 10.00 am in Hall 10 B [UILD] SMART! of MADE EXPO , is intended for all operators in the construction sector, with particular reference to concrete, from the producers of materials and components to construction companies, to the managers of the building and infrastructure assets, to technical and administrative decision makers.

The proposal is advanced, with the sponsorship of ACI Italy chapter , by the consortium of two important European industrial research projects, admitted to the Horizon 2020 funding program (four-year period 2018-2021), which involve research institutions and important industrial subjects to cover the entire value chain of the concrete construction industry. Both projects aim to develop and implement advanced cement-based materials and new solutions and design approaches that have as their main objective the improvement of durability and functionality throughout the life cycle of reinforced concrete structures, even in extreme conditions.

The speakers, chosen from among the participants in the research groups involved, will provide an updated overview of the most current issues concerning the durability of reinforced concrete structures and infrastructures and the most up-to-date solutions and methodologies to address them at the various technical-operational-decision levels.

Reinforced concrete and Corrosion

The structural assessment of existing buildings and infrastructures is becoming a crucial issue in many industrialized countries. Since most of the existing structures have already reached the end of their nominal life, it becomes of fundamental importance to evaluate the actual conditions of the structural elements in order to estimate whether it is possible to extend the use of the structure in safe conditions and in order to predict , if necessary, an optimized strategy of reinforcement interventions.

Corrosion of reinforcement: an important cause of degradation
One of the main causes of degradation in reinforced concrete structures is certainly the corrosion of the reinforcements. The damages caused by corrosion are not always visible to the technicians but the effects on the structural behavior are relevant as they not only cause a reduction in the performance of the structures subjected to static loads but also have repercussions on the seismic behavior (such as localized deformations, reduction of the capacity in resistance and ductility). Therefore knowing how to predict the behavior of infrastructure structures subject to material degradation can help put in place prevention tools designed to mitigate the effects of aging structures.

The day “Capacity Assessment of Corroded Reinforced Concrete Structures” is a study day in which international professionals and academics will present the results of their studies, both experimental and numerical, inherent to the behavior of structural elements in conglomerate armed with reinforcing bars subject to corrosion.

The CACRCS DAY represents a perfect opportunity for exchange on the progress in the field of modeling of structures in reinforced concrete subject to material degradation.

Registration for the event is free and open to engineers, technicians, researchers, academics and professionals. To register please send an e-mail to beatrice.belletti@unipr.it possibly by March 10th 2019.

Authors interested in presenting a work during the CACRCS DAY are invited to submit an abstract of 300 words, in accordance with the theme, by 10 March 2019. The works that will be presented during CACRCS DAY, may be submitted to the Fib Structural review Concrete and, if accepted, will be published in a special issue of Structural Concrete Journal. The documents must follow the format of the journal and must be sent by May 31st 2019.
