Description
Testo della descrizione dell’invenzione industriale dal titolo “Materiale cementizio fibro-rinforzato per applicazioni strutturali e non strutturali” Text of the description of the industrial invention entitled "Fiber-reinforced cementitious material for structural and non-structural applications"
Testo della Descrizione Description text
L’invenzione in oggetto consiste in un materiale composito a matrice cementizia con caratteristiche meccaniche e di resistenza alla temperatura elevate, rinforzato con fibre con elevate caratteristiche meccaniche, rinforzato, sia in forma sciolta, sia in forma composita mediante inglobamento in una opportuna matrice non cementizia. Il materiale è ottenuto attraverso la premiscelazione, a secco delle tre fasi ovvero la componente cementizia , le due fasi fibrose precedentemente descritte, le ulteriori componenti necessarie al conferimento delle proprietà desiderate e dalla successiva aggiunta di una fase liquida di opportuna composizione. Il materiale oggetto di brevetto, usato come rinforzo strutturale di murature, è in grado di modificare il meccanismo di rottura delle stesse, consentendo Γ innalzamento delle sollecitazioni sopportate dalle stesse. Il materiale è ottenuto attraverso la premiscelazione a secco della componente cementizia, di quella fibrosa e delle ulteriori componenti necessarie al conferimento delle proprietà desiderate e da una successiva aggiunta di una fase liquida di opportuna composizione. The invention in question consists of a composite material with a cementitious matrix with mechanical characteristics and resistance to high temperatures, reinforced with fibers with high mechanical characteristics, reinforced, both in loose form and in composite form by incorporation into a suitable non-cementitious matrix. . The material is obtained through the dry premixing of the three phases or the cement component, the two fibrous phases previously described, the additional components necessary to confer the desired properties and the subsequent addition of a liquid phase of suitable composition. The patented material, used as a structural reinforcement of masonry, is able to modify the breaking mechanism of the same, allowing Γ raising of the stresses borne by them. The material is obtained through the dry premixing of the cement component, of the fibrous one and of the other components necessary to confer the desired properties and by a subsequent addition of a liquid phase of suitable composition.
La matrice cementizia ha la funzione di conferire la geometria al pezzo, d proteggere le fibre dalle temperature elevate e dagli agenti corrosivi operando al contempo il trasferimento dei carichi esterni alle fibre de rinforzo. Tale matrice cementizia può avere diversa composizione e formulazione in funzione delle caratteristiche finali che si voglion ottenere. The cement matrix has the function of conferring geometry to the piece, of protecting the fibers from high temperatures and corrosive agents while operating at the same time the transfer of external loads to the reinforcing fibers. This cementitious matrix can have different composition and formulation depending on the final characteristics to be obtained.
La granulometria della matrice cementizia deve essere estremamente fine in modo da garantire il perfetto inglobamento delle fibre del rinforzo. The granulometry of the cementitious matrix must be extremely fine in order to guarantee the perfect incorporation of the reinforcement fibers.
Le fasi fibrose utilizzate come rinforzo garantiscono al pezzo realizzato tale materiale, elevate caratteristiche meccaniche e di durabilità nel tempo e di leggerezza al confronto di soluzioni alternative in grado di garantire uguali proprietà meccaniche. La geometria e la tipologia delle fibre in oggetto è funzione delle caratteristiche che si vogliono conferire al manufatto realizzato. The fibrous phases used as reinforcement guarantee the piece made of this material, high mechanical characteristics and durability over time and lightness compared to alternative solutions capable of guaranteeing the same mechanical properties. The geometry and type of the fibers in question depends on the characteristics that are to be given to the manufactured article.
La presenza delle due fasi fibrose consente sia di conferire elevate caratteristiche meccaniche al materiale, sia di eliminare le microfessurazioni da ritiro. Un’opportuna formulazione dei componenti costituenti il materiale consente la creazione di un legame chimico tra le fibre sciolte di rinforzo e la matrice cementizia con evidenti miglioramenti nel comportamento del materiale realizzato. La finitura superficiale della seconda fase fibrosa è progettata in modo da garantire la migliore aderenza nella matrice cementizia. La lunghezza delle fibre sciolte non deve essere necessariamente costante e va valutata in funzione delle applicazioni ed è comunque compresa tra 2 e 25 mm. The presence of the two fibrous phases allows both to give high mechanical characteristics to the material and to eliminate shrinkage micro-cracks. An appropriate formulation of the components making up the material allows the creation of a chemical bond between the loose reinforcing fibers and the cement matrix with obvious improvements in the behavior of the material made. The surface finish of the second fibrous phase is designed to ensure the best adhesion in the cement matrix. The length of the loose fibers does not necessarily have to be constant and must be evaluated according to the applications and is in any case between 2 and 25 mm.
La lunghezza delle fibre composite non deve essere necessariamente costante e può essere compresa tra 10 e 120 mm. The length of the composite fibers does not necessarily have to be constant and can be between 10 and 120 mm.
Le fibre utilizzabili sono tutte quelle esistenti ed utilizzabili nella realizzazione di materiali compositi. The usable fibers are all those existing and usable in the production of composite materials.
In funzione delle caratteristiche che si vogliono ottenere si possono aggiungere alla composizione del materiale opportuni lattici sia in fase liquida che solida. Depending on the characteristics to be obtained, suitable latexes in both liquid and solid phase can be added to the composition of the material.
La diversa formulazione delle diverse fasi descritte consente di ottenere una malta con caratteristiche meccaniche e di lavorabilità tali da adattarsi alle più svariate necessità applicative. The different formulation of the different phases described allows to obtain a mortar with mechanical and workability characteristics such as to adapt to the most varied application needs.
Il materiale in oggetto può essere posto in opera sia manualmente sia mediante procedure semi o completamente meccanizzate. The material in question can be applied either manually or by means of semi or fully mechanized procedures.
