Evento rivolto a chi vuole conoscere la cultura e le tradizioni costruttive della Lessinia e costruire con materiali naturali.
Antonia Stringher ci parlerà della cultura cimbra, così vicina a noi, ma ancora poco conosciuta. In particolare delle case della Lessinia fatte di paglia, pietra e legno, cioè quello che era disponibile sul posto.
Case semplici, ma durature, funzionali e belle.
Costruire con la paglia è più che mai attuale.
L’architetto Nicola Preti mostrerà una recente casa fatta con la paglia che ha interpretato la filosofia costruttiva della Lessinia.
Interverrà Claudio Gaiga, costruttore di case in paglia di Selva di Progno.
Spiegherà come ha convinto il committente a utilizzare la paglia per ristrutturare una piccola contrada.
Scopriremo perché la paglia, il legno, la calce e l’argilla sono materiali da rivalutare per costruire abitazioni sane e sicure.

Originalmente servía como lugar de contratación de mercaderes y albergaba el tribunal mercantil y la primera entidad bancaria del país. Está constituido por tres cuerpos que dan a la plaza del mercado: la Lonja, el edificio del consulado y una torre. La fachada principal presenta esculturas con significados simbólicos relacionados con los pecados.
This document discusses different types of dental cements used for cementation of fixed prosthodontic restorations (FPDs). It describes the ideal requirements, mechanisms of retention, and bonding mechanisms of luting agents. Various cements are discussed in detail, including their properties, applications, advantages and disadvantages. Zinc phosphate, zinc silicophosphate, zinc polycarboxylate, glass ionomer, resin, and zinc oxide eugenol cements are all compared. Cement selection depends on the clinical situation and luting procedure involves isolation, moisture control, and post-cementation instructions.
Nanotechnology has applications in dentistry including for local anesthesia and preventing tooth decay. One study used magnet-directed nanoparticles containing a local anesthetic drug to numb ankle nerves in rats. Researchers are also investigating using iron-containing nanoparticles to catalyze hydrogen peroxide to break up dental plaque bacteria and prevent cavities. A new smart material is being designed to fill cavities with drug-loaded silica nanoparticles that self-assemble and provide a long-lasting antimicrobial effect to stop bacteria and prevent recurrent decay.
This document provides a detailed history and overview of dental ceramics. It discusses the origins and composition of different types of ceramics used in dentistry like feldspathic porcelain, leucite-reinforced porcelain, and aluminous porcelain. The document also outlines the various methods used to classify and fabricate dental ceramics, including processes like condensation and sintering, casting and ceramming, machining, pressure molding, and glass infiltration. Key developments in the history of using ceramics in dentistry are highlighted from the 1700s to present day.
The presentation deals with dental ceramics from a material aspect and discusses various types of metal - ceramic and all - ceramic systems available in dentistry with their advantages and drawbacks. It is well supported with illustrations..
The document discusses ceramics used in dentistry, including their history, classification, composition, strengthening mechanisms, properties, shade matching guidelines, and fabrication of metal ceramic and all-ceramic dental restorations. Ceramics are classified based on their composition, processing methods, translucency, and firing temperature. Their fabrication involves metal preparation, condensation of ceramic powder layers, and firing to form a durable bond between ceramic and metal components.
This document discusses dental porcelain, including its composition, manufacturing process, strengthening methods, and applications in ceramic and metal-ceramic restorations. Dental porcelain is a type of ceramic composed of kaolin, silica, and feldspar that is fired at high temperatures. It is used for ceramic crowns, veneers, and metal-ceramic restorations due to its biocompatibility, esthetics, and thermal properties matching enamel and dentin. However, porcelain is also brittle with low tensile strength, so various strengthening techniques are used. Metal-ceramic restorations bond porcelain to metal frameworks, requiring thermal and chemical compatibility between the materials.

A complete denture is a removable dental prosthesis that replaces the entire dentition and associated structures of the maxilla and mandible. It is composed of artificial teeth attached to a denture base, which is typically made of heat-cured or chemically-cured denture base resin. Heat-cured resin requires processing using a polymerization cycle involving water baths at different temperatures, while chemically-cured resin polymerizes at room temperature. Both resin types are biocompatible but heat-cured resin tends to be stronger with less porosity and distortion compared to chemically-cured resin.

Costruire con paglia e canapa: innovare naturalmentecasedacoltivare
Presentazione di costruzioni realizzate con materiali naturali in canapa e paglia durante l'incontro al Fab Lab Verona. Sono intervenuti l'arch. Nicola Preti, l'arch. Francesco Adami e l'artigiano Piergiorgio Tittoni dell'impresa Edilfortuna.
Con la paglia la casa è ecologica e risparmiosacasedacoltivare
Quando si dice “casa in paglia”, si pensa subito alla favola dei tre porcellini e all’inconsistenza di un materiale che non resiste al soffio del lupo. Meglio il solito mattone.
Eppure oggi le case in paglia non hanno niente a che vedere con lo stereotipo che tutti noi abbiamo in mente.
[...]
Negli ultimi anni la realizzazione di un rilevante numero di architetture e spazi sacri “molto discutibili” ha fatto emergere a livello di dibattito scientifico il significato dell’edificio in rapporto alla funzione di spiritualità insita in esso e a un contesto sociale e urbano in mutamento. Partendo da questo presupposto e dall’idea di una Costruzione universalmente riconosciuta, il volume raccoglie l’esperienza del primo Corso di alta formazione “La costruzione di un edificio nella città moderna: architettura, arte e progetto urbano”.

La scelta dei materiali per una riqualificazione energetico-ambientale - Mic...YouToBeGreen
Michele Pietropaolo, architetto e presidente della sezione Pesaro-Urbino di INBAR (Istituto Nazionale di BioArchitettura), ci spiega quali sono i concetti base della bioarchitettura e ci illustra case history interessanti per la costruzione e riqualificazione di immobili adibiti alla ricezione e agli eventi.
Similar to Case in paglia: come la storia ci insegna a costruire il futuro (20)
Sono Nicola Preti e dal 2006 ho iniziato a lavorare e fare esperienza nel settore dell'architettura.
Mi occupo di progettazione e direzione dei lavori di edifici pensati per assicurare il benessere dell'uomo.
Sono esperto in progettazione e riqualificazione di edifici con l’utilizzo di materiali naturali.
Riqualificazione energetica in canapa e calce di un edificio a Veronanicola preti
La canapa è un materiale naturale, che tradizionalmente veniva coltivato in Veneto per usi tessili.
Oggi lo abbiamo riscoperto per costruire o ristrutturare gli edifici in modo naturale.
L'evento è stato l'occasione per raccontare il progetto di ristrutturazione di un'abitazione degli anni '60 a Borgo Roma in cui è stata utilizzata la canapa per fare un cappotto termico e per costruire i nuovi muri.
L’utilizzo di prodotti isolanti naturali e altamente traspiranti ha permesso a fine intervento, di raggiungere un'elevatissima efficienza energetica ed un alto comfort abitativo.
Sono intervenuti Nicola Preti, architetto progettista della ristrutturazione, Daniele Scala, titolare del negozio Fior di Canapa, e Eliana Rapisarda, fondatrice del giornale online Verona Green e la committente dell'abitazione.

Biodesign: exhibition on the cross-pollination of nature, science and creativitynicola preti
About the Exhibition:
Biodesign highlights 57 newly developed materials and applications that utilize biology for design, art and architecture. These explorations highlight the possibility of working with life in a variety of ways, from supporting a building with trees to recycling waste and growing fabric with microbes. Several of these innovations work to align our behavior with the preservation of natural resources, to erect bridges between ecosystems and the built environment and demonstrate that the two can benefit and ultimately sustain one another.
The exhibition is curated by William Myers and is based on his book BioDesign published by The Museum of Modern Art and Thames & Hudson in 2012.
Presentazione del progetto "Orientamenti Urbani", ovvero di un contenitore di iniziative culturali pluriennali nato per riflettere sull'evoluzione della città.
Il progetto è frutto della convenzione stipulata tra il Politecnico di Milano e il comune di San Giovanni Lupatoto (Vr)
Nella presentazione ho voluto mettere in luce i temi di fondo: #soggetti #lavoro #ambiente urbano #nomadworker
La frasi di alcune slides sono state riprese da presentazioni di Michele Vianello (http://www.michelecamp.it) che mi hanno aiutato a sintetizzare i contenuti.

4. LE ABITAZIONI DEI COLONI CIMBRI
In questa prima parte partiremo col prendere in
considerazione le prime abitazioni dei coloni cimbri,
scesi in Lessnia dalla Baviera e dal Tirolo subito dopo il
Mille con il compito di disboscare la faggeta onde creare
pascoli per le greggi per alimentare il mercato della
lana, così fiorente nella città di Verona.
“Zimber” così essi si definivano, ovvero boscaioli,
artigiani del legno -
Si stabilirono nella foresta e là costruirono “ de huttan”
le loro prime dimore
5. “Hutte”costruita con sistema “ pit inkastranholtz” o
“Blockbau”, consta di un unico locale dove coabitano
persone e animali. Fango e sterco chiudono le
fessure.Il tetto è costituito da “stikanbasan, stroube.
6. Esempio di hutte con sistema blockbau – il fuoco era al
centro, circondato da pietre e il fumo usciva dalla porta.
7.
8. Da quelle prime abitazioni si passò via, via, ad abitazioni
di muro, legno, coperte di paglia. ( doc 1407)
Nacquero così le contrade, piccoli agglomerati sparsi sul
territorio che rispondevano alle esigenze dei Cimbri.
L’architettura della Lessinia presenta varie tipologie che
risentono delle risorse naturali del territorio; in Lessinia
centr. e occ. dominò la pietra, il lastame, ( pietra di Prun
– Rosso Ammonitico) mentre in Lessinia or. si costruì
con sassi di vajo o di torrente, i tetti coperti a coppi fatti
con argille presenti in loco o in paglia. A Giazza vi erano
due fornaci; quella presente in contrada Sichilj ce la
ricorda Il top. “ Zichel “ = mattonaia.
In Lessinia centrale e occ. erano di pietra pure i tetti
delle abitazioni ma non delle “tede” che erano di paglia.
Ciò permetteva al fieno di “respirare” e quindi
mantenersi sano.
9. I Gauli – tipica contrada della Lessinia or. – disposizione
a schiera dove si alternano case, stalle, fienili.
18. Giazza – edifici alti tre/quattro piani con tetti di coppi
un tempo prodotti con argille rosse del luogo
19. Tetti di paglia
Costruiti completamente in legno e paglia; pure il
materiale per legare e i chiodi, erano di legno.
I Cimbri preferivano la paglia di segale molto resistente,
lunga e sottile.
Questo cereale, poco esigente e amante dei terreni
magri, cresceva bene sulla nostra montagna.
Molte famiglie lo seminavano principalmente per questo
scopo e secondariamente per il chicco ( pane nero)
La trebbiatura, effettuata spesso su aie ben levigate
con sterco di vacca, ( Lessinia orientale) veniva fatta
con estrema cura affinché non rimanesse nemmeno un
chicco che potesse attirare uccelli e topi con
conseguenze immaginabili. Un tetto di paglia di segale
durava 30/40 anni senza fare grandi manutenzioni .
22. Tetto di paglia – connessione fra travi con chiodi di legno detti
“bironi” – i più idonei erano di “dase de pesso”(abete rosso) lunghi
circa 30 cm con diametro di 3 ca. Questo legno era molto
resistente, manteneva le dimensioni e non veniva intaccato dai
tarli. Il foro veniva fatto con apposita trivella e un po’ di sbieco.
23. Roverè – costruzione tetto di paglia – spessore 20 cm
Talvolta la pendenza è di 40°/ 60°
24. Interno tetto di “teda” formato da laste di Rosso
Ammonitico e falde di paglia o canna palustre.
31. Baito Malera di Sotto
1941
Metà corpo coperto a paglia
e metà in lastre di Rosso
Ammonitico.
Baito Malera di Sotto oggi
Fino all’800 i baiti degli
alpeggi erano di legno e
coperti a paglia.
Spesso, per incuria dei
conduttori o causa fulmini
andavano a fuoco.
37. Particolare del tetto di
lastre – le piccole
scanalature e le quintane
poste sopra la giuntura
delle lastre garantiscono
un’ottima tenuta dagli
agenti atmosferici
44. Roverè – Stalla del Modesto – particolare costruzione
con lastre di Rosso Ammonitico posizionate a “cortel” e
connesse agli angoli con la tecnica del “ blockbau”
45. Giassara attigua alla stalla del Modesto a due porticine
una per l’immissione delle lastre di ghiaccio, l’altra per
estrarle.
46. Baito della Porcarina – 1535
In origine sul retro vi era il baito accorpato poi alla
casara
47. Malga Buse di Sotto – porcile e pollaio con lastre
a “cortel”.
51. “La riduzione o l’aumento di circa il
40% dell’anidride carbonica
presente nell’atmosfera potrebbe
innescare reazioni responsabili
dell’evoluzione o involuzione delle
ere glaciali”
Svante Arrhenius
Premio Nobel per la Chimica 1903
53. Edifici e cambiamento climatico
Gli edifici consumano il 40%
dell’energia globale ed emettono un
terzo dei gas a effetto serra.
Il settore delle costruzioni ha il
potenziale più alto per regolare a
lungo termine l’effetto serra.
Gli edifici hanno un ciclo di vita lungo, e per
questo le costruzioni di oggi influenzeranno le
emissioni di gas serra dei prossimi anni.
Ridurre le emissioni degli
edifici porta benefici
economici e sociali.

Passiv Haus ha
analizzato per
due anni i livelli
di VOC
(composti
organici volatili)
di una casa
passiva fatta in
mattoni e isolata
con cappotto in
polistirene.
Inquinamento interno degli edifici
59. Il risultato: il livello di pentano, una sostanza tossica
presente nel polistirene, è più alto dei livelli consentiti.
L’edificio è in classe A, ma è nocivo per la salute.

62. Perché progettare con la paglia?
La paglia è lo stelo della
pianta morta dei cereali.
Ha una composizione
chimica simile al legno.
Il fieno invece è erba
verde essiccata.
Esso tende a deperire
facilmente.
PAGLIA FIENO≠
63. Perché utilizzare la paglia?
SOSTENIBILITÀ
La paglia è un prodotto naturale rinnovabile annualmente, scarto
dell’agricoltura. La Gran Bretagna ne produce un surplus di 4 milioni di t.
ogni anno.
EFFICIENZA ENERGETICA ED EMISSIONI DI GAS SERRA
Più del 50% dei gas serra è prodotto dall’industria di costruzioni.
Se i 4 milioni di t. di paglia in eccesso fossero imballati e utilizzati
localmente per la costruzione, potremmo edificare almeno 450.000 case di
150 mq/anno.
La costruzione in balle di paglia può causare una netta riduzione
dell’emissione di gas serra.
64. Perché utilizzare la paglia?
BASSO RISCHIO
INCENDIO
I muri in balle di paglia
intonacati presentano un
minor rischio di incendio
dei muri tradizionali
eretti con strutture di
legno.
Diverse prove di
laboratorio hanno
mostrato che un muro di
paglia intonacato resiste
90 minuti al fuoco.
65. Perché utilizzare la paglia?
RESISTENZA SISMICA
Le case in paglia sono
più sicure rispetto alle
abitazioni in laterizio o
calcestruzzo.
Avendo una massa
inferiore, il materiale
risente meno delle
sollecitazioni del terreno
e la sua deformabilità e
flessione consente
l’assorbimento delle
accelerazioni e
vibrazioni, riducendo la
possibilità di fratture.
66. Perché utilizzare la paglia?
UN AMBIENTE SANO PER VIVERE
La paglia è una sana alternativa ai
materiali moderni. Vivere tra muri di
paglia può migliorare la qualità dell’aria
che respiriamo, perché a differenza di
molti materiali moderni, non emette
sostanze nocive come la formaldeide.
Inoltre si tratta di un materiale
traspirante che contribuisce a tenere
fresca l’aria all’interno della
costruzione.
UNA CASA PIÙ ECONOMICA
Anche sul fronte dei costi, rispetto a un
edificio tradizionale il risparmio è di
circa il 30%. Mediamente si va dai
1.100 €/mq a 1.400 €/mq.

103. C'è pericolo di topi e ratti?
NO
La paglia è lo stelo vuoto delle piante dei
cereali e, a differenza del fieno, non contiene
cibo che attrae animaletti pelosi.
Una volta intonacati i muri di paglia ai topi
non sembrano diversi da qualunque altro
muro.
Se intonacate i vostri muri di paglia con calce/
argilla e fate la manutenzione, non ci saranno
buchi per invitarli ad entrare o spazi dove
possano vivere.
(fonte: Barbara Jones, Costruire con le balle di paglia, Terra nuova edizioni)
104. È possibile riparare i muri di paglia?
SI
Non soltanto è possibile ma anche molto
facile!
La parte più difficile è fare un buco nella
paglia. Per farlo si usa un martello da
carpentiere (dalla parte per strappare i chiodi)
o un piede di porco, e semplicemente si
strappa la paglia.
L'esperienza ha dimostrato che se una parte
di un muro si bagna, l'umidità rimane
sorprendentemente ferma nello stesso punto.
Non tende a diffondersi nella paglia e la parte
bagnata può essere rimossa e sostituita.
(fonte: Barbara Jones, Costruire con le balle di paglia, Terra nuova edizioni)
105. Posso utilizzare la paglia per fare un
ampliamento alla mia casa?
SI
Dovete considerare attentamente
l'assestamento e non collegare i muri della
casa originaria ai muri dell'ampliamento prima
che questi ultimi siano stati compressi.
Potete anche fare un ampliamento alla vostra
casa di paglia semplicemente tagliando il foro
per una porta.
Alcune famiglie hanno spinto i figli a costruirsi
nuovi spazi appena raggiunta l'età adatta!
(fonte: Barbara Jones, Costruire con le balle di paglia, Terra nuova edizioni)
106. Che altro si può costruire con la paglia?
SCUOLE, UFFICI, MAGAZZINI, CAPANNONI
La paglia è stata utilizzata per molte cose.
A parte case, studi, uffici e spazi comuni, la paglia è
stata utilizzata per costruire scuole, magazzini, fienili
e stalle, studi di registrazione, centri di meditazione,
barriere acustiche per aeroporti e autostrade, depositi
alimentari e fattorie.
