Castable, rheoplastic, structural, controlled shrinkage grout mortar

Code: GRT.0070

Components: 1

Appearance: Powder

GROUT 6 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 6 mm. It is ideal for restorations, reinforcements and seismic adjustments for medium-to-high thicknesses (4–15 cm), on structures in reinforced concrete and masonry.

Use fields

Structural restoration, dimensional adjustments, reinforcements, high dimension anchorages, drawing and armouring works, etc., by pumped or poured casting installation. Realisation of structural road joints.

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

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).

Application methods

- Pour out

Tool cleaning

- Water

Permitted supports

- Concrete

- Mixed walls (bricks and stones)

- Prefabricated concrete

- Rusty reinforcement rods

Warnings, precautions and Ecology

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.
