Super-fluid composite structural mortar for concrete with reduced thickness

Code: FLR.0265

Components: 1

Appearance: Powder

This rheoplastic, composite cementitious grout with controlled-shrinkage and super-fluid consistency is fibre-reinforced with a special mix of steel (READYMESH MM-150) and polypropylene fibres, having a base of high-strength cements, polymeric modifiers, anti-shrinkage agents, super-pozzolanic reactive fillers and selected siliceous aggregates. It is ideal for restoring the thickness of concrete removed by milling, of old concrete flooring (with a reconstruction thickness from 15 mm to 40 mm), along with dimensional adjustments, structural reintegration and so on, where high resistance to static and dynamic stresses is required.

FLOOR Q SFR has a working time of about 60 minutes, after which the gripping process is triggered followed by progressive hardening. Plastic and hygrometric shrinkage are extremely low, ensuring volumetric stability when restored. The benefits of FLOOR Q SFR include:
• resistance to dynamic stress;
• resistance to fatigue, fracture energy, toughness and resistance to post-breaking loads;
• high mechanical compressive resistance (>70 MPa at 28 days);
• high mechanical flexion-tensile resistance (>13 MPa at 28 days);
• excellent durability and resistance to chemical attacks.


Approximately 21 kilograms/square metre of FLOOR Q SFR per centimetre of thickness to be achieved (approximately 2100 kilograms per cubic metre).

Use fields

Repair and coating of industrial concrete flooring, structural reintegration, dimensional adjustments, increase of cross-section resistance, reconstruction of the thickness of concrete removed through milling. Restorations and structural reinforcements where high resistance to static and dynamic stresses is required.

Preparation of supports

The applicative surfaces must be clean, free from contamination or any loose or crumbling parts, dust, and so on, suitably saturated with water. In the event of surfaces to be reconstructed after milling, the reconstruction areas must be as even (and square-shaped) as possible. The thickness is to be as homogeneous as possible. Finally, the section to be filled with the pre-existing flooring must recall the shape of a trapezoid that widens downwards (in order to perfectly anchor the “patch” in the site of reconstruction and prevent its detachment, given the slightly expansive properties of the product).

Use method

In the restoration of industrial floors, adopt the necessary measures to ensure adequate mechanical collaboration between the restoration and substrate. To do so, there are 2 alternative ways in which to proceed:
- spread the epoxy primer specific for structural cast recovery (SYNTECH RGS) on the prepared surface with a roller or brush;
- prepare a suitable additional reinforcement, parallel to the base of the reconstruction, consisting of welded mesh (2 mm wire, 5 x 5-centimetre mesh) at half the distance from the base and secured to the base by means of “L” steel bars with a 6-cm diameter to improved adhesion, fitted into the specific holes and fastened with MICRO-J GROUT expansive cement mortar or polyester resin in the extrusible two-component cartridge SYNTECH PROFIX. For structural restorations carried out by means of formwork castings, carefully dismantle the surfaces of the formwork. Allow at least 48 hours before dismantling. To prepare the mortar, add 2/3 of the total water of the blend into the concrete mixer, gradually adding the product and the remaining water until obtaining a homogeneous mixture of the desired consistency. Once prepared, take the mixture to the reconstruction site then trowel on until completely smooth.
