Castable structural, reinforced, controlled shrinkage shotcrete

Code: GRT.0071

Components: 1

Appearance: Powder

GROUT 6 SFR is a high-performance, self-levelling castable mortar, being fibre-reinforced with READYMESH MM-150 steel fibres and 6 mm READYMESH PM-060 polypropylene microfibres, with high flexural strength, great adhesion to concrete and steel, and shrinkage compensation. Aggregates with a maximum size of 6 mm. It is ideal for anchoring road joints, restorations, reinforcements and seismic adjustments, offering ductility for medium-to-high thicknesses (5–20 cm), on structures in reinforced concrete and masonry.

Use fields

Structural restoration and adjustments, recovery and anchoring of road, motorway, airport joints and critical area joints in general.

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).

Use method

Pour about 2/3 of the mixing water into the mixer, add GROUT 6 SFR and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 13%-15% by weight (3.5-4.5 litres per bag). Adopt casting procedures capable of ensuring the absence of discontinuities and avoid the formation of air pockets.

For high anchoring sections it is appropriate to add GHIAIETTO 6.10 (please refer to the appropriate technical data sheet for more information).
