DESCRIZIONE DESCRIPTION
“STRATO DI FINITURA PER PAVIMENTI IN CEMENTO†⠀ œFINISHING LAYER FOR CONCRETE FLOORSâ €
La presente invenzione inerisce ai pavimenti in conglomerato cementizio per fabbricati industriali e civili. The present invention relates to cement conglomerate floors for industrial and civil buildings.
E’ noto che la pavimentazione dei locali adibiti a lavorazioni industriali o a ricovero di attrezzi viene effettuata nella maggior parte dei casi mediante gettate di conglomerato cementizio, o calcestruzzo, pavimentazione che risulta tutt’ora la più vantaggiosa in rapporto alle prestazioni ed al costo. It is known that the flooring of the premises used for industrial processing or tool shed is carried out in most cases by means of cement conglomerate, or concrete, flooring that is still the most advantageous in relation to performance and cost. .
La prima operazione che viene eseguita à ̈ la stesura del getto in conglomerato cementizio, che viene opportunamente livellato. The first operation that is performed is the laying of the concrete mix, which is suitably leveled.
A questa operazione fa seguito una serie di attività intese a realizzare una conveniente finitura superficiale al getto di conglomerato. This operation is followed by a series of activities aimed at achieving a convenient surface finish on the concrete casting.
Queste attività comprendono lo spargimento sulla superficie del getto di una polvere indurente comprendente generalmente cemento. These activities include spreading a hardening powder generally comprising cement on the surface of the casting.
Questa operazione, conosciuta dai tecnici come “spolvero†, avviene spargendo a secco la polvere a mano, o con adatti attrezzi, sino a realizzare uno strato di finitura avente uno spessore di qualche millimetro, generalmente da 2 a 5 mm. This operation, known by technicians as â € œspolveroâ €, takes place by spreading the powder dry by hand, or with suitable tools, until a finishing layer is created having a thickness of a few millimeters, generally from 2 to 5 mm.
La polvere viene lasciata riposare sino ad assorbire una certa quantità di acqua dal sottostante calcestruzzo non ancora indurito; il tempo di riposo à ̈ di qualche minuto. The powder is left to rest until a certain amount of water is absorbed by the underlying concrete not yet hardened; the rest time is a few minutes.
Successivamente lo strato di polvere viene livellato e lisciato mediante attrezzature note. Subsequently, the powder layer is leveled and smoothed by means of known equipment.
L’effettuazione di dette operazioni richiede che lo strato di finitura, dopo l’assorbimento dell’acqua da sottostante strato di cemento, mantenga caratteristiche di plasticità e scorrevolezza tali da non compromettere la livellatura e la lisciatura. Carrying out these operations requires that the finishing layer, after absorbing the water from the underlying concrete layer, maintains characteristics of plasticity and smoothness such as not to compromise leveling and smoothing.
L’operazione di spolvero à ̈ tuttavia origine di un grave inconveniente che ne pregiudica negativamente la effettuazione. However, the dusting operation is the origin of a serious inconvenience which adversely affects its execution.
L’inconveniente nasce dalla incontrollata e notevole generazione di polvere molto fine, che ristagna negli ambienti per lungo tempo e rende necessaria la adozione di mezzi di salvaguardia della salute degli operatori, come maschere e simili. The drawback arises from the uncontrolled and considerable generation of very fine dust, which stagnates in the environments for a long time and makes it necessary to adopt means of safeguarding the health of the operators, such as masks and the like.
Sono noti materiali a base di cemento in polvere che hanno subito trattamenti intesi a ridurre la formazione di povere durante la manipolazione nei successivi impieghi. Powdered cement-based materials are known which have undergone treatments intended to reduce the formation of dusts during handling in subsequent uses.
I materiali noti sono ad esempio descritti nei seguenti documenti: Known materials are for example described in the following documents:
WO 20067084588 WO 20067084588
GB 1190903a GB 1190903a
Tuttavia detti materiali non sono risultati adatti a formare uno strato di finitura in primo luogo perché lo strato da essi formato non possiede sufficienti caratteristiche meccaniche e di durezza, ed in secondo luogo perché essi sono carenti delle uniformi caratteristiche granulometriche necessarie al loro corretto ed omogeneo spargimento. However, said materials were not suitable for forming a finishing layer firstly because the layer formed by them does not possess sufficient mechanical and hardness characteristics, and secondly because they lack the uniform granulometric characteristics necessary for their correct and homogeneous spreading.
La presente invenzione ha lo scopo di ridurre grandemente il suddetto inconveniente, rendendo disponibile un materiale adatto alla effettuazione della operazione di “spolvero†senza sensibile creazione di polvere. The present invention has the purpose of greatly reducing the aforementioned drawback, making available a material suitable for carrying out the "dusting" operation without sensitive creation of dust.
Lo scopo dell’invenzione viene conseguito mediante un materiale di finitura, in forma di polvere, avente le caratteristiche recitate nella rivendicazione indipendente. I materiali in polvere, secondo il trovato, pur essendo a base di cemento e sostanze antipolvere, dopo il trattamento debbono infatti mantenere caratteristiche di uniformità granulometrica e di scorrevolezza tale da consentirne la omogenea applicazione, la livellatura e la lisciatura finale. The object of the invention is achieved by means of a finishing material, in the form of a powder, having the characteristics recited in the independent claim. The powder materials according to the invention, even if they are based on cement and anti-dust substances, after the treatment must in fact maintain characteristics of granulometric uniformity and smoothness such as to allow their homogeneous application, leveling and final smoothing.
Lo strato creato col materiale secondo il trovato deve inoltre mantenere caratteristiche igroscopiche tali da consentire l’uniforme assorbimento di acqua dal sottostante strato di conglomerato cementizio non ancora giunto a maturazione.

ESEMPIO 1 EXAMPLE 1
In un capannone ad uso industriale destinato a contenere macchine ed attrezzature per lavorazioni meccaniche, Ã ̈ stato creato un pavimento di 1.000 mq comprendente uno strato di fondo di conglomerato cementizio armato. In a shed for industrial use intended to contain machinery and equipment for mechanical processing, a floor of 1,000 square meters was created including a bottom layer of reinforced cement conglomerate.
La superficie del suddetto strato à ̈ stata opportunamente livellata e lasciata a riposo per circa 5 ore sino al parziale maturazione atta a conseguire un consolidamento sufficiente a sopportare il peso (calpestio) di una persona. Contemporaneamente, in un sito distante dal cantiere, sono stati preparati 4000 Kg. di una polvere di finitura avente la seguente composizione (percentuali in peso): The surface of the aforesaid layer has been suitably leveled and left to rest for about 5 hours until partial maturation, in order to achieve sufficient consolidation to bear the weight (foot traffic) of a person. At the same time, in a site far from the construction site, 4000 Kg. Of a finishing powder with the following composition (percentages by weight) were prepared:
cemento tipo Portland 38 % Portland cement 38%
sabbia silicea 61 %, 61% silica sand,
olio di vaselina 1,0 % vaseline oil 1.0%
Il cemento e la sabbia silicea sono stati miscelati in un adatto miscelatore per circa 60 secondi, e quindi à ̈ stato spruzzato nel miscelatore l’olio di vaselina. The cement and silica sand were mixed in a suitable mixer for about 60 seconds, and then vaseline oil was sprayed into the mixer.
Dopo circa 30 secondi di miscelazione, il materiale così ottenuto si presenta in forma di una polvere secca omogenea con granulometria compresa tra 0.01 e 3 mm, che viene confezionata in sacchi. After about 30 seconds of mixing, the material thus obtained is presented in the form of a homogeneous dry powder with a particle size between 0.01 and 3 mm, which is packaged in bags.
La polvere di finitura viene cosparsa in modo omogeneo sulla superficie del calcestruzzo parzialmente matura (indurita),sino a formare uno strato omogeneo di circa 2 mm avente buone caratteristiche igroscopiche. The finishing powder is spread homogeneously on the partially mature (hardened) concrete surface, to form a homogeneous layer of about 2 mm with good hygroscopic characteristics.
Lo strato di povere viene quindi lasciato riposare per circa 2 minuti primi. The poor layer is then left to rest for about 2 minutes.
Durante questo tempo la polvere, che possiede buone caratteristiche igroscopiche, ha assorbito acqua dal sottostante strato di calcestruzzo, ed acquisito una consistenza sufficientemente pastosa da consentire una operazione di livellatura e lisciatura. During this time the powder, which has good hygroscopic characteristics, has absorbed water from the underlying concrete layer, and acquired a sufficiently pasty consistency to allow a leveling and smoothing operation.
Dopo vari passaggi di lisciatura effettuata con appositi attrezzi lo strato di finitura si presenta perfettamente liscio, con spessore di circa 2 mm, proprietà idrorepellenti e di resistenza meccanica dell’ordine di 450 Kg/cm<2>(dopo almeno 28 gg di maturazione) After several smoothing steps carried out with special tools, the finishing layer is perfectly smooth, with a thickness of about 2 mm, water-repellent properties and mechanical resistance of the order of 450 Kg / cm <2> (after at least 28 days of maturation )

Cement, quartz, micro silica, calcium formate, melamine, polypropylene fiber, iron oxide, titanium dioxide, silver ions and silica sand were mixed in a suitable mixer for about 60 seconds, and then vaseline (60 kg equal to 1.5%) was sprayed into the mixer.
Dopo circa 30 secondi di miscelazione, il materiale così ottenuto si presenta in forma di una polvere secca omogenea con granulometria compresa tra 0.01 e 3 mm, che viene confezionata in sacchi. After about 30 seconds of mixing, the material thus obtained is presented in the form of a homogeneous dry powder with a particle size between 0.01 and 3 mm, which is packaged in bags.
La polvere di finitura ottenuta secondi gli Esempi 1 e 2 viene cosparsa in modo omogeneo sulla superficie del calcestruzzo parzialmente indurita,sino a formare uno strato omogeneo di circa 2 mm avente buone caratteristiche igroscopiche. The finishing powder obtained according to Examples 1 and 2 is spread homogeneously on the partially hardened concrete surface, until it forms a homogeneous layer of about 2 mm having good hygroscopic characteristics.
Lo strato di povere viene quindi lasciato riposare per circa due minuti primi. The lean layer is then left to rest for about two minutes.
Durante questo tempo la polvere, che possiede buone caratteristiche igroscopiche, ha assorbito acqua dal sottostante strato di calcestruzzo, ed acquisito una consistenza sufficientemente pastosa da consentire una operazione di livellatura e lisciatura. During this time the powder, which has good hygroscopic characteristics, has absorbed water from the underlying concrete layer, and acquired a sufficiently pasty consistency to allow a leveling and smoothing operation.
