WHAT IS SIKAGROUT?

SikaGrout 4R is ready to use, self leveling and shrink free cement mortar with a grain size of 0/4mm. In the liquid-plastic phase, it is characterized by a small expansion and normal growth endurance . The mortar complies with the principles of structural repairs regarding the anchoring of steel reinforcing bars in accordance with PN-EN 1504-6. In addition, it also meets the requirements for class R4 repair mortar in accordance with PN-EN 1504-3. The material can also be used fine-grained self-compacting concrete with a strength class of at least 34-45.

What properties does mortar have?

SikaGrout 4R is easy to use, just add water and it is ready to use. Thanks to the fact that we can add the right amount of water ourselves, we can easily adjust its consistency. The minimum layer is 1.5 cm and the maximum is 5 cm. Locally, the thickness of the layer can be doubled, i.e. it can be up to 10 cm. The mortar is self-levelling, strength build-up is normal and final strength is high. In addition, it expands by gas evolution while still in the liquid-plastic phase. Once set, SikaGrout 8N is vibration and impact resistant as well as watertight and frostproof. The material is non-toxic and non-flammable, the reaction to fire class is A1.

USAGE

SikaGrout®-4 R is primarily used as a flowing grout or anchor mortar with a layer thickness/distance from the anchor to the walls of the hole between 1.5 cm and 5 cm.

Locally, the maximum thickness of the mortar layer may be greater than 5 cm, up to 10 cm. It is also possible, after appropriate tests, to add a good quality aggregate to the material (in the amount of 25-35% of the dry component weight, depending on the aggregate quality) and use it as a fine-grained self-compacting concrete (SCC). The use of additional aggregate does not affect the amount of mixing water.

    • Grouts for machines, poles, etc.
    • Embedding anchors, bars, railings and other steel structures in concrete
    • Pouring joints of prefabricated elements
    • Filling defects and gaps in concrete on horizontal surfaces
    • Suitable for repair work (principle 3, method 3.2 of EN 1504-9). Repair of flaked or damaged concrete in buildings, bridges and other reinforced concrete structures.
    • Suitable for structural reinforcement (principle 4, method 4.2 of EN 1504-9). Increasing the bearing capacity of the concrete structure by installing reinforcing bars in the openings.
    • Suitable for structural reinforcement (principle 4, method 4.4 of EN 1504-9). Increasing the bearing capacity of the concrete structure by adding a layer of mortar.
    • Suitable for maintaining or restoring passivity (principle 7, method 7.1 and 7.2 of EN 1504-9). Increased concrete cover and replacement of damaged or carbonated concrete.

    APP INFORMATION

    Mixing ratio

    Use a maximum of 12% of mixing water (3.0 liters of water for 1 bag of 25 kg). If necessary, the liquidity of the material can be reduced by reducing the amount of water, but to a level not lower than 11%. In the case of additional graining, use only very good quality washed aggregates of 4/8 or 5/8 mm fraction - e.g. those required for high-strength hydrotechnical or bridge concretes. The recommended amount ranges from 25-35% of the weight of the dry ingredient (depending on the density, form and roughness of the grains and the required leveling of the ready mix).

    The use of additional aggregate does not affect the amount of mixing water.

    Wear

    Depending on the roughness of the substrate and the thickness of the layer. Approx. 18 kg of dry mortar per 1 m² per 1 cm layer thickness.

    Efficiency

    One 25 kg bag yields an average of 12.5 - 13.5 dm3 of fresh mortar.

    Layer thickness

    Minimum 1.5 cm / maximum 5 cm (when used as a grout or anchor mortar).

    Locally, the maximum thickness of the mortar layer may be greater than 5 cm, up to 10 cm. It is also possible, after carrying out appropriate tests, to additionally grain the material with good quality aggregate (in the amount of 25-35% of the weight of the dry component, depending on the quality of the aggregate).

    setting time

    From 5 to 10 hours.

    Frost resistance after 24 hours at a curing temperature of + 5 °C (the mortar must not be exposed to frost during this time).
