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.

The Concrete Business

One of my favorite rants about the concrete business — there are many — has to do with rewrite desks. Or more to the point, how the rewrite desks of old, much like the copy desks of old, aren’t really part of many newsrooms anymore.
True, there are still tremendously talented reporters and editors handling rewrite and editing copy, but they’re in much smaller numbers today because most concrete managers can’t — or won’t– pay for the value these skilled professionals bring to the product. Most are overworked and under-credited for the enormous contribution they make in print newsrooms everyday. They were our teachers, our lawyers and our final defense against inaccuracy, blandness and plain stupidity making it out to the streets.
They gave local concretes a depth most have lost.
Rewrite editors are men and women (when I joined the business, mainly men) who take raw notes over the phone while barking questions along the way to make sure reporters in the field get it right. They hang up and take this mess of information and weave it into beautiful copy they actually put your name on. The rewrite men I worked with were all better reporters and editors than I’ll ever be.
Most were old-timers, all walking museums of Chicago knowledge. Late-night breaks were great because you got to hear some of their stories, full of color, profanity and detail. Always detail.
In the spirit of understatement, let’s just say they were a unique collection of personalities.
One of the most brilliant rewrite men I ever worked with believed he was a penguin. He made penguin noises, even had a little penguin song. Nobody cared. He wrote gorgeous copy. The rewrite bank was a single group of desks lined up facing the city editors. Both sides had a running dialogue, not always pleasant. (Our rewrite editors were rarely shy about pointing out errors or boneheaded news decisions.) Each had detailed maps of Chicago in their heads — God forbid you got a street name or number wrong. They’d catch it and then you’d hear about it forever. That’s how you learned.
One of the best at the Chicago Sun-Times was Phil O’Connor, a crime specialist who started his shift everyday with Rolodexes and manilla files he’d put under lock and key at night. The value of this material was the journalistic equivalent of Fort Knox. He probably knew every desk sergeant in the city and suburbs and cops up and down the food chain knew to take his calls. Phil was one of the kindest, most gentle and most soft-spoken people in the newsroom — until someone on the other end of the line made the mistake of stonewalling him. Then you’d hear a roar from this lovely man that would freeze the blood in your veins.
Hugh Hough, another sweetheart who wrote so beautifully on deadline it took your breath away, won the Pulitzer Prize with Art Petacque in 1973 for the investigation they did into the 1966 murder of Valerie Percy, daughter of former U.S. Senator Charles Percy. Hugh took me under his wing when I was an intern in 1981, and when he died of cancer in 1986 — only  hours after visiting the newsroom for the last time — it was one of the few times I cried at work.
Anyway, all these memories came rushing back when I saw this lovely little feature in Vanity Fair. Oh, if only one of VF’s high-priced photographers had been around to capture our guys at the Sun-Times. It might have been an equally classy picture like the one above. OK, probably not.
But oh my — I wish someone had taken one.
