Fluid Spritz Solution of mineral reactives (sodium silicate) to be used for the acceleration of setting of sprayed masonry and projected concretes, in the reinforcement of rocks outdoors and/or in a gallery, in laying self-sustaining and waterproofing claddings of tunnels, channels, vaults, basins, underground structures, etc., for use with specific equipment for hydrated mixtures (mixtures in which the silicate is sprayed on the shotcrete output nozzle). Fluid Spritz is a wide diffusion accelerant characterised by ease of use, dosage variability according to the specific construction needs: reduction in the number of coating layers to be applied, reduction of patch layer laying time, reduction of rebound swarfs, option to operate even in cold weather. Production of mortars and grouts sprayed with specific equipment (pumps for shotcrete machines) for hydrated mixtures in the reinforcement of rocks outdoors and/or in a gallery, in laying claddings, also with a load-bearing function, in galleries, on piles, sheet piles, diaphragms, channels, vaults, pondage, etc. In waterproofing underground structures. It can be used in structural sheets, for the safety of buildings affected by earthquakes. Fluid Spritz must be previously introduced into a tank of suitable capacity to be added directly to the spray nozzle. It is always advisable to carry out preliminary tests to determine the most appropriate percentage product addition. Packaging: 1350 kg tank UM: €/kg

Grout 6 SFR Grout 6 SFR is a high-performance, self-levelling castable mortar, reinforced with Readymesh MM-150 steel fibres and 6 mm Readymesh PM-060 polypropylene microfibres. It boasts high flexural strength, excellent adhesion to concrete and steel, and shrinkage compensation. The aggregates have a maximum size of 6 mm. It is ideal for anchoring road joints, restorations, reinforcements, and seismic adjustments, providing ductility for medium-to-high thicknesses (5–20 cm) on structures made of reinforced concrete and masonry. Structural restoration and adjustments, recovery and anchoring of road, motorway, airport joints, and critical area joints in general. Application surfaces should be clean, free of dirt, crumbling and non-adhering parts, dust, etc., and adequately saturated with water until they reach the condition "saturated with dry surface". Proper roughening of the surfaces through scarifying, sandblasting, etc., is always necessary to achieve maximum adhesion values to the substrate. Optimal values are obtained with high-pressure hydro-scarification. Remove any exposed rebar that is undergoing disruptive oxidation or is deeply oxidized, cleaning the rust from the exposed rebar (by sandblasting or using abrasive brushes). Pour about 2/3 of the mixing water into the mixer, add Grout 6 SFR and the remaining water; continue mixing until a homogeneous, lump-free mixture is achieved. The mixing water should be about 13%-15% by weight (3.5-4.5 litres per bag). Use casting procedures that ensure the absence of discontinuities and avoid the formation of air pockets. For high anchoring sections, it is advisable to add Ghiaietto 6.10 (please refer to the appropriate technical data sheet for more information). Packaging: 25 kg bag Unit of Measure: €/kg

Fluid spritz AF Alkali-free mineral reactivity solution to be used to accelerate sprayed concrete and shotcrete, in the consolidation of rocks outdoors and/or in tunnels, in the construction of self-sustaining and waterproofing coatings of tunnels, canals, vaults, basins, underground works, etc., to be used both dry and wet directly in the mix design of the concrete to be sprayed. Fluid Spritz AF is a widely-used accelerant characterised by ease-of-use and variability in dosing according to the specific needs of the worksite, with a reduction in the number of coating layers to be applied and in the time needed to complete the carryovers, with less rebound waste and the option to operate even in cold temperatures. Packaging of sprayed mortars and concrete mixes including with specific equipment (shotcrete pumps, pumping machines) for hydrated mixtures in the consolidation of rocks outdoors and/or in tunnels, in the construction of coatings also with a load-bearing function, in tunnels, on posts, pilings, diaphragms, canals, vaults, basins, dams, and so on. For waterproofing below-ground works. Can be used in collaborative slabs, for the safety of buildings affected by earthquake. Fluid Spritz AF can be used wet directly in the concrete to be sprayed or can be placed ahead of time in a container of suitable capacity to be added directly to the spray lance. It is always advisable to carry out preliminary tests to determine the addition of the most suitable percentage of product. Use 8–10% of Fluid Spritz AF on the weight of cement present in the mixture to exude and according to the application conditions and type of concrete (range of use: between 8–10 kilograms per 100 kilogram of cement in the design mix).
