Definitions

  • the present invention relates to a grout composition, its use and the production process therefor.
  • the invention relates to a grout composition and use thereof for pointing purposes, especially for floorings and wall coverings made using ceramic slabs or tiles, natural stones or like products in substantially slab form.
  • the laying of ceramic slabs or tiles generally involves spreading, on the surface to be clad, a layer of mastic or other adhesive, and then applying the slabs or ceramic tiles on the layer.
  • the slabs or tiles are flanked to one another such as to realise a continuous covering.
  • the appearance of the finished cladding is therefore characterised by the presence of a plurality of slabs or ceramic tiles separated by a grid network of grout-filled spaces; the grout must therefore also exhibit aesthetic and functional characteristics which will last over time.
  • the lines filled with cement grout which remains porous to a certain extent and is therefore susceptible to some degree of water absorption, become home to microorganisms such as mould, bacteria or fungus, which cause unpleasant coloration and odours in the grout, as well as stains and even a deterioration in the actual grout.
  • An aim of the present invention is to obviate the above-cited drawback.
  • a further aim of the invention is to attain the objective in the ambit of a simple, rational and relatively inexpensive solution.
  • the invention makes available a grout composition comprising at least a bond and at least an inorganic anti-bacterial agent destined to be dispersed in the bond.
  • composition comprising a given substance X
  • composition comprising a given substance X
  • a composition comprising a given substance X
  • the antibacterial agent is therefore dispersed in the whole mass of the bond.
  • the action of the antibacterial agent is such as to inhibit the growth of bacteria, fungus or moulds; furthermore, as it is inorganic in nature, it does not wear away over time and maintains its antibacterial effect over the whole working duration of the grout.
  • the grout composition advantageously further comprises at least an inert material, for example exhibiting a granulometry comprised between 0.01 mm and 1 mm, which is also destined to be dispersed in the bond, with the aim of guaranteeing the grout qualities of high mechanical resistance to abrasion over time.
  • an inert material for example exhibiting a granulometry comprised between 0.01 mm and 1 mm, which is also destined to be dispersed in the bond, with the aim of guaranteeing the grout qualities of high mechanical resistance to abrasion over time.
  • the bond is selected from among hydraulic bonds, such as for example cement, hydraulic lime, aluminium cement, natural pozzolana materials, artificial pozzolana materials and the like;
  • the inert material is selected from among calcium carbonate, quartz and silicon sand or a mixture of the three above-named components.
  • the inorganic antibacterial agent is advantageously constituted by silver ions, preferably stabilised on glass support elements, or clay support elements or the like, known as carriers.
  • the silver ions are such as to inhibit growth of microorganisms, such as bacteria, mould and fungus, inasmuch as they bond to the cellular structure of the microorganisms such as to interact with the enzymatic synthesis.
  • microorganisms such as bacteria, mould and fungus
  • the silver ions intervene in the duplicating mechanism of the microorganisms' DNA, facilitating formation of species that are reactive to oxygen and which thus enable the grout to be kept clean.
  • the bond for example the cement, is preferably present in quantities comprised between 20% and 60%, the inert material is present in quantities of between 38% and 79.98%, while the silver ions are present in quantities of between 0.02% and 2%.
  • the grout composition advantageously further comprises a pozzolana additive in quantities comprised between 0% and 2%, which gives the compound better mechanical resistance and chromatic stability.
  • the pozzolana additive improves and contributes to the elimination of any efflorescence due to the presence of free lime in the cement constituting the bond.
  • the preferable pozzolana additives are microsilicates or amorphous silicates or metakaolins.
  • the grout composition of the invention further comprises a grip accelerator in quantities comprised between 0% and 1.5%.
  • the accelerator has the function of shortening grout drying times, once it has been laid.
  • Grip accelerators that can advantageously be used are aluminium sulphate or formiated lime.
  • the grout composition can comprise a fluidifier in quantities comprised between 0% and 0.5%, such as to reduce the water/bond ratio when it is prepared for laying, improving the mechanical resistance and the abrasive resistance.
  • the fluidifier can be an additive based on polycarboxylate ethers or melamine sulphonate.
  • composition of the invention can also comprise colorant pigments in quantities of between 0% and 5%,
  • the grout composition comprises titanium dioxides in quantities comprised between 0% and 3%, which improves the brilliancy and the chromatic effect of the grout.
  • composition of the invention further comprises a soluble copolymer in powder form in quantities comprised between 0% and 3%, which enables a reduction in water absorption of the grout after the grout has hardened, i.e. following laying.
  • the grout composition can further comprise cellulose ether in quantities comprised between 0 and 0.2% with the aim of improving the rheology of the grout, which translates into a greater applicability of the grout during the laying thereof, for example, in the spaces between the tiles.
  • composition of the invention can advantageously comprise a water- repellent in power form, in quantities comprised between 0% and 1 %, which enables a further reduction in the water absorption following hardening of the grout, once the grout has been laid.
  • Portland cement (white or grey) in class I 52.5 R present in quantities of 30%; quartz having a granulometry of between 0.1 and 0.3 mm and in a 40% quantity;
  • iron oxide pigment in a 0.5% quantity; titanium dioxide in a 1 % quantity;
  • silver ions stabilised on a carrier for example on glass supports, in a 0.15% quantity.
  • a further aspect of the present invention is the use of a grout composition as a space-filler in floors and wall coverings.
  • a no-less important aspect of the invention is a process for preparation of a composition of the invention, which comprises a stage of batching the weighted quantities, for example using scales, of the powders of the various above-listed components in accordance with, for example, the above- described recipe of the example.
  • the thus-batched powders are then loaded into a coulter or blade mixer for dry-mixing the powders.
  • the mixing can be performed for a few seconds; at the end of the mixing the composition is ready to be sent to a bagging machine such as to be packed in sacks.
  • the anti-bacterial grout it is sufficient to wet the grout with an appropriate quantity of water and mix it; when the paste thus-obtained has reached the desired consistency it is laid in such a way as to penetrate internally of the space to be filled, such as to fill it completely.
  • a rubber spatula or another tool of known type, can be used to lay the grout. Once the grout has been laid, when the grout starts to harden and grip, the spaces can be cleaned. For example a damp sponge can be wiped over the spaces such as to give the grout therein a substantially homogeneous conformation.
