GROUT 6 HP

Castable, rheoplastic and structural concrete with very high strength

Kodi: GRT.0264

Përbërësit: 1

Pamja: Pluhur

GROUT 6 HP is a high-performance castable mortar, equipped with mechanical compressive and bending resistance far superior to normal structural mortars. It is used for repairs, replenishments, strengthening concrete reinforcement and special works in HPC. The special additives contained in the formulation are able to compensate for shrinkage and the development of exceptional rheological characteristics.

Vetitë

With very low water-binder ratios, GROUT 6 HP makes it possible to achieve compacting and hyperfluid rheologies that favour the movement of the mortar and the perfect filling of reinforced sprays, even with narrow spaces between the bars. The microsilica with pozzolanic activity increases the cohesion of the mixture with typical anti-segregating and anti-run-off effect. The particular fineness of the hydraulic binders contained in the formula promotes adherence to the substrate and the rapid development of very high mechanical resistance, even just 24 hours from casting. With regard to the ANTICORROSIVE and PROTECTIVE FUNCTION ON THE REINFORCEMENT BARS, the main features of GROUT 6 HP SFR are:
• the mix of high-strength superfine binders, combined with very fine silicas with pozzolanic activities, to render the mortars intrinsically impermeable to water at the end of the hardening process;
• The strongly alkaline pH (> 12) protects the reinforcement bars from triggering corrosion;
• The negligible breathability of the carbon dioxide ensures hardened mortars with extremely prevalent anti-carbonation characteristics.
Overall, these anticorrosive specificities render the classic treatment of reinforcing bar passivation, preparatory to the pouring of castable mortar UNNECESSARY, provided that not too much time passes between the white metal cleaning operations and the castings of pourable mortar, at the risk of new oxidative processes being triggered. Thus, only in the event that long exposure times are foreseen between the bar-cleaning operations and the pouring of castable mortar is it advisable to treat with passivating slurry (REPAR MONOSTEEL or REPAR STEEL), applied by brush and only on the reinforcing bars.

Approximately 20,5 kilograms/square metre of GROUT 6 HP per centimetre of thickness to be realised (about 2050 kilograms per cubic metre).

Fushat e përdorimit

On-site castings or pumping carried out for any kind of structural replenishment of reinforced concrete, seismic reinforcement and adjustment, increases in cross-sectional resistance of concrete structures and masonry, anchorages of large-scale machinery, anchoring of port bollards, deep-drawing and reinforcement works, restoration of highly-stressed industrial flooring both from a static and dynamic perspective, restoration of degraded foundations on bridges and viaducts especially whereby necessitating rapid reopening to vehicle traffic, construction of structures designed with HPC (High Performance Concrete) needs.

Përgatitja e shtresave

Application surfaces must be clean, free of dust, contamination, crumbling, inconsistencies, etc., and adequately saturated-surface-dry with water.

Mënyra e përdorimit

Mix the entire content of a bag of GROUT 6 HP with effective vertical-axis mixers for at least 6 minutes, initially introducing a slightly reduced amount of water (9% = 2.25 litres/25 kilograms bag) compared to the required total water permitted (10%–12% = 2.5 litres–3.0 litres/25-kilogram bag) whilst mixing for at least 4 minutes. After this mixing time, evaluate the consistency of the mixture and, if necessary, gradually add in the last of the water until achieving the desired workability, without exceeding the limit of 12% (3.0 litres/25-kilogram bag), mixing at high RPM for at least another two minutes. For thick casting sections, it is advisable to add GHIAIETTO 6.10 (consult the relevant technical data sheet or ask for more information on the appropriate dosage of GHIAIETTO 6.10 from our technical service). Given the self-levelling properties of the product and its self-compacting capacity, paying due attention to the vibration phase is recommended. Excessive zeal in the vibration operation can worsen the aesthetic rendering of the end result. Do not use in the absence of suitable lateral containment. Ensure exposed surfaces are protected and wet-cured. Adopt casting procedures to ensure the absence of voids and discontinuities. Only pour the mortar from one part of the casting perimeter to avoid air pockets.
