Restaurarea cladirilor vechi din caramida printr-o tehnica inovativa

curatare caramida

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.

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.

Tree, Line by Zander Olsen .//


If you are fans of Felice Varini you will enjoy this one. ‘This is an ongoing series of constructed photographs rooted in the forest. These works, carried out in Surrey, Hampshire and Wales,involve site specific interventions in the landscape, ‘wrapping’ trees with white material to construct a visual relationship between tree, not-tree and the line of horizon according to the camera’s viewpoint.’

Philippe Ramette's Surrealism .//

Philippe Ramette is the living proof that some people prefer the hard old fashioned way of doing things. What may look like a photomontage is actually a real image envisioned and portrayed by French artist Philippe Ramette and photographed by his collaborator Marc Domage with the aid of some hardware.

Kids vs Queensland Gallery of Modern Art .//


. Albert Einstein said that in order to stimulate creativity, one must develop the childlike inclination for play and the childlike desire for recognition and the following collaboration between a few kids and Queensland Gallery of Modern Art strengthens his words.
Artist Yayoi Kusama designed an entire room filled with white domestic objects and then thousands of colored dots stickers were given to kids to decorate the room. It took two weeks to finish the installation turning the room into a genuine explosion of colors.

"The secret of genius is to carry the spirit of childhood into maturity."

Back in Business.//


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.

Bending Buildings.//


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 at the Ponte Milvio .//


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.

Denis Smith's Lightwritting.//


I've previously posted about Lichtfaktor's lightwritting but the Australian photographer Denis Smith took this technique to the next level. Pushing the boundaries of light graffiti, Smith has produced something mysterious and mythical light shapes.
