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 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
