Grout 2 HP: Rheoplastic, structural, anti-shrinkage mortar with very high resistance

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
