Restaurarea cladirilor vechi din caramida printr-o tehnica inovativa

Sablara caramizii este o metoda relativ noua de curatare a zidariei construite recent, chiar daca acest sistem de curatare a fost folosit de mai multi ani in munca de restaurare a zidariei.

Multi arhitecti/ ingineri prefera acest tip de  curatare al caramizii in locul metodelor de curatare cu acid. Curatarea caramizii cu acid poate crea reactii adverse si poate duce la deteriorarea suprafetei.

Pentru a beneficia de cele mai bune rezultate in urma curatarii caramizii prin sablare, este important sa se apele la ajutor calificat in domeniu.

Curatarea caramizii implica urmatoarele echipamente: compresorul de aer portabil, rezervorul de sablare, duza de sablare, costum de protectie pentru operant.

Rezervorul de sablare este incarcat cu materiale abrazive, pentru ca mai apoi amestecul de aer comprimat si material abraziv sa fie propulsat in furtunul de sablare si mai apoi spre duza.

Modelul de curatare al caramizii este determinat de catre dimensiunea duzei, tipul si presiunea aerului. Viteza de curatare a caramizii este determinata de tipul de abraziv utilizat, dimensiunea duzei, tipul duzei, presiunea aerului si de catre distanta dintre duza si perete. Nu in ultimul rand, viteza de curatare mai depinde si de starea suprafetei care urmeaza sa fie curatata.

Tipul de materiale abrazive folosite de obicei pentru curatarea caramizii sunt:

-          nisipul

-          cuart

-          granit

Materialul abraziv de curatare trebuie sa fie in conformitate cu unul dintre cele doua tipuri de dimensiuni ale particulelor

1.      Tipul A: acest tip se folosete in cazul in care zidaria este usor murdara, sau cand este permisa numai o texturare foarte usoara sau fina a zidariei.

2.      Tipul B: acest tip se folosete pentru curatarea petelor dificile de mortar de zidarie, sau cand este permisa o texturare medie a zidariei.

Sablarea poate fi utilizata pentru curatarea tuturor tipurilor de caramida arsa, neteda sau texturata.

Caramizile facute manual sau cele extrem de vechi prezinta riscul de a fi deteriorate in cazul in care se foloseste sablarea pe suprafata acestora.

Ca o masura de precautie suplimentara, inainte de a apela la acest tip de serviciu trebuie mai intai sa se primeasca o aprobare din partea producatorului de caramida.

Recomandari:

1.      Zidaria trebuie sa fie uscata si veche de cel putin 7 zile pentru a putea fi curatata.

2.      Inainte de sablare, toate particulele mari de mortar trebuie sa fie eliminate cu unelte de mana. Utilizati palete din lemn sau dalti.

Pentru o curatare fara a afecta suprata se poate apela la sablare cu gheata carbonica.

3.      Asigura o protectie adecvata pentru toate suprafetele adiacente zonei de lucru. Utilizati folie de plastic si banda adeziva pentru a proteja ferestrele/ usile.

After a long time of neglecting this blog (only three posts in 2011), I've decided it's time to resume posting and bookmarking all those lovely and creative artworks out there as another tool of expressing myself. Furthermore, to kick it up a notch each post will contain a track and quote alongside with the story itself. All related. Something for the mind, ear and eyes.

First the streets of Paris (at least in Inception), now the facades of Lyon. In December, the Théatre des Celestins was the location of an unlikely phenomenon in the architecture world: a classical Beaux-Arts building smushed into a Gehry-esque blob. And all thanks to the vocal patterns of a very captive audience.

Locks of love are the padlocks fixed by loving couples to symbolize their eternal love.
A couple would hang a padlock after inscribing their name or initials on it and throw the key away so that their love is locked forever.

Oscar Diaz | Ink Calendar

.

"Ink Calendar" makes use the timed pace of the ink spreading on the paper to indicate time.

The ink is absorbed slowly, and the numbers in the calendar are "printed" daily. One a day, they are filled with ink until the end of the month. A calendar self-updated, which enhances the perception of time passing and not only signaling it.

The ink colors are based on a spectrum, which relate to a “color temperature scale”, each month having a color related to our perception of the whether on that month. The colors range from dark blue in December to, three shades of green in spring or oranges, red in the summer.

The scale for measuring the “color temperature” that I have used is a standard called ‘D65’ and corresponds roughly to a midday sun in Western / Northern Europe.

The "Ink Calendar" was developed for “Gradual “, an exhibition featuring works, which were evolving during the exhibition time at the London Design Festival 2007.

Fainting goats .//

.

This breed of goat was once used by farmers, kept in the pastures with sheep and other small livestock. When wolves and coyotes would attack, the goat would be frightened and faint, so the predator would get the goat while the rest of the animals fled to safety…and this is where the term “scapegoat” originated.

This is one of mother nature’s cruel sick jokes.
