Grout 2

Rheoplastic, structural, anti-shrinkage mortar, for precision anchorage

Grout 2 is a high-performance, self-levelling pourable mortar that is fibre-reinforced with Readymesh PM-060 microfibres, with high durability even in aggressive environments, great adhesion on concrete and steel and compensated shrinkage. Aggregates with a maximum size of 2 mm. Ideal for anchoring machinery with subplate casting, anchoring seismic isolators and embedding bars, for repairs and reinforcements that are quite thin (2–6 cm) on reinforced concrete and masonry structures.

    Grout 2

    Grout 2 is self-leveling, perfectly pourable, with a maximum aggregate size of 2 mm, and is able to completely fill the most tortuous cavities, normally inaccessible, even if far from the casting point and with a very narrow air gap. The high content of microsilic with pozzolanic activity and the absence of "bleeding", help to generate a very strong adhesion to the substrate and to the foundation or reinforcement iron. Other features are the elimination of plastic shrinkage, the compensation of hygrometric shrinkage, excellent durability to chemical attacks, freeze and thaw cycles, resistance to fats and oils.
    The exceptional ANTI-CORROSIVE and PROTECTIVE capacity ON REINFORCEMENTS is achieved thanks to the following properties:
    • the mix of highly resistant superfine binders, combined with very fine silicas with pozzolanic activity, makes the mortars, at the end of the hardening process, intrinsically impermeable to water;
    • the strongly alkaline pH (> 12) protects the reinforcing rods from the initiation of corrosion;
    • the negligible breathability to carbon dioxide gives the hardened mortars very high anti-carbonation characteristics.
    The combination of these anticorrosive specificities makes the classic passivation treatment of reinforcing bars, preparatory to the casting of the pourable mortar, NOT NECESSARY, provided that, between the white metal cleaning operations and the castings of the pourable mortar, it does not elapse too long. time, with the risk of a new start of oxidative processes. Therefore, only if long exposure times are foreseen between the cleaning operations of the iron and the castings of the pourable mortar, it is advisable to treat with passivating grout (Repar Monosteel or Repar Steel), applied with a brush and localized only on d 'armor. For the construction of road joints, in works with high vehicle traffic, it is possible to add Grout 2 with 25 kg / m³ (300 gr / 25 kg bag) of Readymesh MM-150 steel fibers and 1 kg / m³ (10 gr / bag) of Readymesh PM-060 polypropylene fibers.

    Fields of application
    Precision anchorage of operating machines: presses, turbines, power supplies, rolling mills, alternators, bridge cranes, metal structures, tracks, etc. Structural adjustments, restorations, drawing and armouring, through injections or castings poured in caisson. Realisation of connecting anchorages through steel bars with diameter and depth consistent with design specifications, through casting in perforations provided for this purpose. Construction of structural road joints.
    Allowed supports
    Concrete
    Prefabricated concrete
    Mixed walls (bricks and stones)
    Rusty reinforcement rods
    Preparation of supports
    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". 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).
    Mode of use
    Insert 2/3 (approximately 2.5 litres per bag) of the total mixing water in the cement mixer, then gradually add the product and the remaining water, mix until a homogeneous lump-free mixture of the desired consistency is obtained.

    For high anchoring sections Ghiaietto 6.10 should be added (please refer to the appropriate technical data sheet for more information).

    Warnings
    Given the self-levelling properties of the product and its self-compacting properties, it is recommended to pay special attention to the vibration step. A excessive zeal in the vibration operation can worsen the aesthetic appearance of the resulting product.

    Do not use in the absence of adequate lateral confinement.

    Cure the protection and the moist hardening of exposed surfaces.

    Adopt casting procedures capable of ensuring the absence of gaps and discontinuities, pouring the mortar from a single part of the casting perimetre to avoid air pockets.The general information, along with any instructions and recommendations for use of this product, including in this data sheet and eventually provided verbally or in writing, correspond to the present state of our scientific and practical knowledge.
