An anti-dust chemical/mechanical revitalising hardener for concrete flooring and screeds, consisting of an aqueous solution of mineral silicates and fluosilicates, activated by specific wetting agents. It is applied in several coats of decreasing dilution in water, with a brush or mechanical “scrubber”. Specific anti-dust treatments for industrial flooring or concrete slabs that have lost their original “vitality”. It reacts with the calcium compounds, soluble and unstable, present in of concrete products, transforming them into new stable, insoluble and resistant compounds. Consequent increases in resistance to wear and tear of the order of 200% -400%, significant increases in chemical stability, resistance to freeze-thaw cycles etc. Reactive impregnations for stabilising chemical and mechanical structures and concrete products. Hardening, anti-dust, anti abrasive and anti-corrosion treatments for concrete floorings. Adjustment of the chemical and mechanical performance of products for the industrial, rural and livestock construction (on horizontal surfaces). Apply, preferably with a brush or with "washer dryer" machine on the basis of the following indications: - Porous surfaces: repeated applications of a solution of water and QL Fluosil at a ratio in 1:1 - Compact surfaces: apply three coats, with decreasing dilution with water. 1a coat 1:3, 2a coat 1:2, 3a coat 1:1. The consumption of QL Fluosil will be proportional to the absorption of the floor to be treated. Indicatively a porous surface will consume about 400 g/m², while a surface with normal porosity will consume 250-300 g/m². Leave the product to dry between one coat and the next and then, after the last coat, wash with copious amounts of water. Protect glass and aluminium surfaces during application. Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface".

Grout CR Composite , castable, anti-washout, controlled shrinkage cement mortar, superfluid consistency, based on high-resistance cements, superpozzolanic fillers (MICROSIL 90), polymeric modifiers, shrinkage resistant agents, specific additives, calcium silicate mineral fibres, selected silica aggregates. - Based on of thickened silica fume - three-dimensionally reinforced fibre with mineral and synthetic fibres - Provides high adherence and adhesion - dimensionally stable (shrinkage-compensated) - Provides high stability-physical chemical and resistance to chlorides and sulphates - suitable for underwater castings: it is anti-washout - high strength in terms of hydrostatic positive and negative thrust. Repair and protective coatings of hydraulic structures, marine and underwater structures, and articles in critical situations: harsh chemical-physical, leaching water, marine atmosphere, etc. Filling of formwork for the containment of cast immersed in sea water. In case of underwater application, the installation operations must be carried out within 8-10 hours of cleaning and "fouling" (accumulation and deposits of organic and inorganic particles on product surfaces) removal. An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes). Pour 2/3 of total mixture water in the cement mixer, gradually add the product and the remaining water, until a homogeneous mixture of the required consistency is obtained. For sizable filling thicknesses, greater than 60 mm, Ghiaietto 6.10 (inert washed is selected with a particle size of from 6-10 mm) can be added in a percentage ranging from 20% to 40 %, on the basis of practical requirements. In some particularly demanding cases in terms of the resistance to the "dry-wet" cycle (for example, for the action of the tides) or for chemical attacks particularly strong, it would be advisable to add, in addition to the gravel, even thickened silica fume(MICROSIL 90), and in a variable amount depending on the thickness and construction-related need, to further improve the waterproofing and the mechanical strength of the product. In these cases, please contact our Technical Service. In the case of casts in water, make sure of perfect product hardening before removal of the formwork. Approximately 20,50 kg/m² of Grout CR for every centimetre of thickness to be implemented (approximately 2050 kg per cubic metre). Packaging: 25 kg bag UM: €/kg

Grout 6 HP SFR Grout 6 HP SFR is a fibre-reinforced high-performance castable mortar, equipped with mechanical compressive and flexotraction resistance far superior to normal structural mortars. It is used for repairs, replenishments, strengthening concrete reinforcement and special works in FRC. The mix of special metal fibres (Readymesh MM-150) and synthetic fibres (Readymesh PM-060) is able to drastically reduce or even eliminate plastic-hygrometric shrinkage and the development of exceptional characteristics of ductility, fracture energy, resistance to shock and dynamic stress. With very low water-binder ratios, Grout 6 HP SFR makes it possible to achieve compacting and hyperfluid rheologies that favour the movement of the mortar and the perfect filling of reinforced sprays, even with narrow spaces between the bars. The microsilica with pozzolanic activity increases the cohesion of the mixture with typical anti-segregating and anti-run-off effect. The particular fineness of the hydraulic binders contained in the formula promotes adherence to the substrate and has an effect of enlarging the fibrous components. The fibre mix offers strong ductility, toughness and flexotraction resistance to the castings performed with Grout 6 HP SFR. With regard to the ANTICORROSIVE and PROTECTIVE FUNCTION ON THE REINFORCEMENT BARS, the main features of Grout 6 HP SFR are: • the mix of high-strength superfine binders, combined with very fine silicas with pozzolanic activities, to render the mortars intrinsically impermeable to water at the end of the hardening process; • The strongly alkaline pH (> 12) protects the reinforcement bars from triggering corrosion; • The negligible breathability of the carbon dioxide ensures hardened mortars with extremely prevalent anti-carbonation characteristics. Overall, these anticorrosive specificities render the classic treatment of reinforcement bar passivation, preparatory to the pouring of castable mortar UNNECESSARY, provided that not too much time passes between the white metal cleaning operations and the castings of pourable mortar, at the risk of new oxidative processes being triggered. Thus, only in the event that long exposure times are foreseen between the bar-cleaning operations and the pouring of castable mortar is it advisable to treat with passivating slurry (Repar Monosteel or Repar Steel), applied by brush and only on the reinforcing bars. On-site castings or pumping carried out for any kind of structural replenishment of reinforced concrete, seismic reinforcement and adjustment, increases in cross-sectional resistance of concrete structures and masonry, anchorages of large-scale machinery (especially in the presence of significant dynamic stresses), anchoring of port bollards, deep-drawing and reinforcement works, restoration of highly-stressed industrial flooring both from a static and dynamic perspective, restoration of degraded foundations on bridges and viaducts especially whereby necessitating rapid reopening to vehicle traffic, construction of structures designed with HPC (High Performance Concrete) needs. Application surfaces must be clean, free of dust, contamination, crumbling, inconsistencies, etc., and adequately saturated-surface-dry with water. An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes). Mix the entire content of a bag of Grout 6 HP SFR with effective vertical-axis mixers for at least 6 minutes, initially introducing a slightly reduced amount of water (9% = 2.25 litres/25 kilograms bag) compared to the required total water permitted (10%–12% = 2.5litres — 3.0 litres/25 kilogram bag) whilst mixing for at least 4 minutes. After this mixing time, evaluate the consistency of the mixture and, if necessary, gradually add in the last of the water until achieving the desired workability, without exceeding the limit of 12% (3.0 litres/25-kilogram bag), mixing at high RPM for at least another two minutes. For thick casting sections, it is advisable to add Ghiaietto 6.10 (consult the relevant technical data sheet or ask for more information on the appropriate dosage of Ghiaietto 6.10 from our technical service). Given the self-levelling properties of the product and its self-compacting capacity, paying due attention to the vibration phase is recommended. Excessive zeal in the vibration operation can worsen the aesthetic rendering of the end result. Do not use in the absence of suitable lateral containment. Ensure exposed surfaces are protected and wet-cured. Adopt casting procedures to ensure the absence of voids and discontinuities. Only pour the mortar from one part of the casting perimeter to avoid air pockets. Packaging: 25 kg bag UM: €/kg

Grout 2 HP Grout 2 HP is a pourable, fiber-reinforced mortar, used for structural restoration operations, anchoring of steel bars and strands, reinforced micropiles, tie rods, and riveting. The formulation contains very fine high-strength cements, micro-silicas with pozzolanic activity, aggregates in a rational granulometric curve (0.1 ÷ 1.8 mm), and special antisegregative additives. The product is mixed with 11% - 12% of water, requiring vigorous and prolonged mechanical mixing. The special formulation of Grout 2 HP provides the castings with mechanical strength, fracture energy, exceptional durability, and very high chemical-physical resistance. Grout 2 HP has a workability time of about 60-90 minutes, after which the setting process is triggered, followed by progressive hardening. The plastic and hygrometric shrinkage is extremely low thanks to the presence of Readymesh PM-060 multifilament synthetic fibers, which provide volumetric stability. The performances that make Grout 2 HP unique are: • very high compressive mechanical strengths (> 90 MPa at 28 days), • very high mechanical resistance to bending-traction (> 12 MPa after 28 days), • excellent durability and resistance to chemical attacks. Grout 2 HP is used for structural restoration operations, anchoring of steel bars and strands, reinforced micropiles, tie rods, and riveting. It is particularly suitable for operations where high mechanical performance is required after short curing (compressive strength at 3 days > 60 MPa) and in operations carried out in severe exposure environments (XC - XS - XF), characterized by aggression from sulphates, chlorides, and nitrates. The material can also be used for repairs in anchoring areas subject to high stresses. The application surfaces must be clean, free of dirt, crumbly and incoherent parts, dust, etc., and suitably saturated with water until reaching the condition of "saturated with dry surface". Adequate roughening of the surfaces by scarifying, sandblasting, etc. is always necessary to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes). It is strongly recommended, for optimal performance of site operations, to use a vertical axis mixer with planetary movement or a double horizontal helicoid. The powder is mixed with drinking water to the extent of 11% - 12%, referring to the total weight of the mortar (about 2.75 liters per 25 kg bag) until a homogeneous mixture is obtained. Mixing time: about 4 minutes with a high efficiency mixer. The anchoring can be filled with a single screw pump, for mortars. Pumping must be carried out at a controlled speed to ensure a low working pressure. In case of restorations, the surface must be protected, after application, by polyethylene sheets or anti-evaporation treatments. Packaging: 25 kg bag Unit of Measure: €/kg
