Characteristics

GROUT CABLE is a cement-based powder product, suitably added to obtain slurries with very high mechanical resistance, without shrinkage and without “bleeding”, hyperfluid, pourable and self-compacting. The slurries are easily injectable into holes, cavities, discontinuities, cracks and porous conglomerates.
GROUT CABLE's request for mixing water, extremely low, is close to the quantity fixed stably, chemically and physically by the cement (stoichiometric water); this results in exceptional characteristics in terms of stability, performance, impermeability, and durability. The durability is further increased by the high content of microsilicates with pozzolanic reactivity, which distinguishes the product and which gives it very high resistance to sulphates. The presence in the formulation of specific long-chain polymers, with a stabilizing function and also of water retention, allows maturation and development of optimal mechanical performance even in the presence of severe exposure environments (XC, XS, XD, XA). The formulation is free from metal expansives.
Dimensional stability: + 0.4 mm / m (conditions of no loss of water by suction or evaporation)

Consumption

Approximately 1700 kg of GROUT CABLE for each cubic metre of volume to be filled.

Use fields

Consolidation, anchoring and repair of concrete and masonry structures. Filling of cable containment sheaths in post-tensioned structures or anchor rods with the prevention of "stress corrosion" in tensioned steel cables. Maintenance and anticorrosion prevention works of degraded sheaths. Works in concrete or damaged masonry. Consolidation of conglomerates and cracked, damaged or very porous masonry. Bridging of discontinuities. Fastening of steel elements (pins, clamps, connectors). Consolidation and repair of works subjected to environmental, dynamic, hydraulic stresses, such as tunnels, hydraulic, marine, underground works, industrial buildings.

Preparation of supports

Application surfaces should be clean, free of dirt, crumbling and non-adhering parts, dust etc., and saturated with water "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).

Use method

• Pour about 2/3 of the mixing water into the mixer, gradually add GROUT CABLE and the remaining water until a fluid, homogeneous and lump-free mixture is obtained.
• Application temperature> 5 ° C, <35 ° C. The best fluidity is obtained with grout temperature ≥ 15 ° C. Lower temperatures slightly reduce fluidity. With winter temperatures, the use of hot mixing water is recommended.
• Moisten the cavities or conglomerates to prevent the suction of the supports from limiting the smoothness and removing the mixing water before hardening. Wet a few hours before injecting the grout, avoiding water pockets and any excess water on the surface. Clogging and consolidating fillings can be carried out both by gravity and by manual / automatic pumps, depending on the type of application.
• Keep the external and exposed surfaces of the grout moistened for at least 24 hours
