DESCRIZIONE DESCRIPTION
a corredo di una domanda di brevetto per invenzione industriale avente per titolo: accompanying a patent application for an industrial invention entitled:
"Calcestruzzo cellulare autoclavato a ridotto fenome-no di ritiro per la realizzazione di blocchi e/o so-laio e/o pannelli armati e non armati da costruzione" "Autoclaved cellular concrete with reduced shrinkage phenomena for the construction of reinforced and non-reinforced building blocks and / or slabs and / or panels"
La presente invenzione riguarda un calcestruzzo cellulare autoclavato per la realizzazione di blocchi e/o solai e/o pannelli armati e non armati da costru-zione. The present invention relates to an autoclaved cellular concrete for the construction of reinforced and non-reinforced building blocks and / or floors and / or panels.
Più in particolare, l'invenzione riguarda un calcestruzzo del tipo detto che consente di ottenere migliori prestazioni chimico-fisiche e tecnologiche proprie del calcestruzzo del tipo detto, accoppiate con fenomeni di ritiro decisamente migliori e carat-terizzato da migliori prestazioni meccaniche a parità di densità. More specifically, the invention relates to a concrete of the above type which allows to obtain better chemical-physical and technological performances typical of the concrete of the above type, coupled with decidedly better shrinkage phenomena and characterized by better mechanical performances at the same density. .
Come è ben noto, per la realizzazione di bloc-chi e/o solai e/o pannelli armati e non armati da co-struzione attualmente si utilizzano calcestruzzi mi-scelati con vari aggregati, tipo sabbia inerte, gra-nuli di argilla espansa, granuli di polistirolo, in aggiunta a cemento impiegato quale legante. E' altre-sì noto come detti calcestruzzi siano caratterizzati da prestazioni chimico fisiche tecnologicamente ri-dotte. As is well known, concrete mixed with various aggregates, such as inert sand, expanded clay granules, is currently used for the production of reinforced and non-reinforced blocks and / or floors and / or panels for construction polystyrene granules, in addition to cement used as a binder. It is also known that said concretes are characterized by technologically reduced chemical-physical performances.
In termini generali, si tratta di materiali da costruzione pesanti, ad alto consumo di materie pri-me, con bassi valori della conduttività termica, ri-dotta permeabilità al vapore, poco lavorabili, che richiedono l'impiego di abbondanti spessori di malta per la applicazione nella costruzione nonché una cer-ta professionalità per il montaggio. In general terms, these are heavy construction materials, with a high consumption of raw materials, with low values of thermal conductivity, reduced vapor permeability, hardly workable, which require the use of abundant thicknesses of mortar for the application in construction as well as a certain professionalism for assembly.
Inoltre, l'alta percentuale di cemento necessa-riamente presente nell'impasto di tali calcestruzzi rende i manufatti che si ottengono poco vantaggiosi da un punto di vista ecologico e poco naturali, se si considera il particolare processo di costruzione del cemento che richiede alti consumi di energia e conse-guente elevato inquinamento di CO2in atmosfera. Furthermore, the high percentage of cement necessarily present in the mixture of these concretes makes the products obtained not very advantageous from an ecological point of view and not very natural, if we consider the particular cement construction process that requires high consumption. of energy and consequent high pollution of CO2 in the atmosphere.
In alternativa, per la realizzazione di blocchi e/o solai e/o pannelli armati e non armati da costru-zione si utilizzano attualmente calcestruzzi cellula-ri autoclavati che impiegano sabbie silicee, cemento, gesso, calce, e polvere di alluminio come additivo, i quali presentano un elevato fenomeno di ritiro e con-tenute prestazioni meccaniche. Alternatively, autoclaved cellular concretes are currently used for the construction of reinforced and / or non-reinforced building blocks and / or floors and / or panels, which use silica sand, cement, gypsum, lime, and aluminum powder as an additive, which exhibit a high shrinkage phenomenon and moderate mechanical performance.
Alla luce di quanto sopra, il Richiedente ha studiato e messo a punto un calcestruzzo cellulare autoclavato di nuova composizione che presenta carat-teristiche decisamente vantaggiose e migliorative ri-spetto alle soluzioni note, in particolare in termini di composizione chimica, prestazioni chimico-fisiche del manufatto, prestazioni tecnologiche, prestazioni meccaniche, ridotto fenomeno di ritiro e migliore ri-spetto per la natura, minore costo di produzione, ri-sultando pertanto decisamente migliorativo rispetto a quanto già noto nella tecnica. In light of the above, the Applicant has studied and perfected an autoclaved cellular concrete with a new composition which has decidedly advantageous and improved characteristics with respect to known solutions, in particular in terms of chemical composition, chemical-physical performance of the manufactured article, technological performance, mechanical performance, reduced shrinkage phenomenon and better respect for nature, lower production cost, thus resulting in a decidedly better way than what is already known in the art.
In altri termini, il nuovo calcestruzzo cellu-lare autoclavato proposto secondo la presente inven-zione costituisce una soluzione assolutamente vantag-giosa da un punto di vista pratico, economico, di eco-sostenibilità e di bio-compatibilità. In other words, the new autoclaved cellular concrete proposed according to the present invention constitutes an absolutely advantageous solution from a practical, economic, eco-sustainability and bio-compatibility point of view.
Un altro scopo della presente invenzione è quello di fornire un calcestruzzo che sia ecologico e naturale, in quanto costituito da materie prime natu-rali, tipo sabbie, pozzolana, calce e pochissimo ce-mento. Another object of the present invention is to provide a concrete which is ecological and natural, since it consists of natural raw materials, such as sand, pozzolan, lime and very little cement.
Ancora uno scopo della presente invenzione è quello di utilizzare detto calcestruzzo cellulare au-toclavato specificamente per la produzione di solai. Another object of the present invention is that of using said self-tapped cellular concrete specifically for the production of floors.
Un ulteriore scopo della presente invenzione è quello di utilizzare il detto calcestruzzo per la re-alizzazione di pannelli armati e non armati da costruzione, A further object of the present invention is to use said concrete for the construction of reinforced and non-reinforced panels for construction,
