Powder preparation, ready-to-use, based on hydraulic lime, for the preparation, with the sole addition of water, of grout for masonry reinforcement, injectable and castable, high performance in terms of sliding, strength and stability, for ecological building interventions and the restoration of vintage buildings and monuments. In the Sanafluens mixtures, the water is completely and stably incorporated from the hydration reaction of lime; conversely, in traditional mixtures, a very high part of added water, is free, and evapourating, it leaves gaps in the walls. Sanafluens is based on natural hydraulic lime, sodium gluconate, kaolin, aluminates; it does not contain cement, resins, solvents and radioemissive aggregates. Consolidation through injections of brick, stone or mixed masonry, "bag" structures, masonry damaged by the earthquake. Consolidation of masonry affected by capillary rising damp and soluble salts. Consolidation of plasters detached from the masonry support, even with frescoes or of historical and artistic value. Consolidation of foundation structures, pillars, vaults and arches. Clean the application surfaces by spraying abundantly with water. If there is a lack of plaster, apply a suitable render of hydraulic lime and sand (such as Untersana) to close as much as possible the escape routes of the grout once it has been injected. Trace, from bottom to top and from left to right, a 50 cm square grid. On the intersection of the squares, drill the masonry with a rotary drill, with a bit of suitable diameter (depending on the type of masonry to be injected; diameter usually between 12 and 24 mm), to a depth of at least 3/5 of its thickness, tilting the drill downwards by about 10 - 20°. Once all the holes have been drilled, they will be sucked up, blown with compressed air and sprayed with water, to remove the dust inside them produced by the drilling. Insert in the holes for a depth of about 5 cm, transparent meshed rubber tubes, with a total length of at least 30 cm (therefore with about 25 cm external). Properly seal the perimeter of the pipe with Anchorsana Fix accelerated setting grouting mortar to prevent the injected product from escaping. Inject the grout always keeping it lightly mixed and operating a continuous flow, without interruptions. Pour about 2/3 of the mixing water into the mixer. Gradually add Sanafluens and the water still required, continue to mix until a fluid, homogeneous, lump-free grout of the desired consistency is obtained. The mixing water indicatively necessary is equal to 22-24% by weight (5.5 - 6 litres per bag). Reinforcing backfills and fills can be carried out both by gravity and using manual or automatic pumps, depending on the type of application. To verify the effectiveness of the reinforcement, the grout will come out of the pipes adjacent to that in which it is injected. Approximately 1500 kg of Sanafluens for each cubic metre of volume to be filled.

Rinfor Grout Col is a special cementitious formulation, being fibre-reinforced with READYMESH technology, enriched with reactive microsilicates with very high pozzolanic activity and special crystalliser additives that increase the end result and the durability. Mixed with water, it is able to forge micro-concretes with pourable rheology. Once hardened, the product offers exceptional physical-mechanical and ductility values. Ideal for the reinforcement and seismic adaptation of flooring in reinforced concrete, brick-concrete or corrugated sheeting or wood, by constructing a thin extradoxal structural screed along with beams, pillars, structural crosspoints and walls, by means of suitable liners. The rheological and physical-mechanical characteristics of the Rinfor Grout Col product render it extraordinarily effective in reinforcing structural elements in reinforced concrete and masonry. Adhered to the inside of caissons, confined within cavities or spread out over the extrados of foundations and lofts, Rinfor Grout Col allows for low thickness structural reinforcing, substantially devoid of additional metallic reinforcement. Rinfor Grout Col belongs to the HPFRC (High Performance Fibre Reinforced Concrete) family, permitting the structural designer to make use of the following characteristics: - Exceptional resistance and traction as well as exceptional values of shear stress adhesion on various supports which have been suitably roughened; - advantages in structural calculations prescribed for fracture mechanics, resistance to traction and of the ultimate material deformation; - minimum thicknesses applied with reinforcing effects which have been distinctly improved as against interventions with traditional reinforced concrete; - highly notable reduction of mass and minimizing of additional loads applied for structural reinforcing as against interventions with traditional reinforced concrete (practically nil additional loads in the case of the thickness of the coating corresponding with the depth of sacrificed surface); - anti-carbonatation barrier (practically zero penetration of CO2) and anti-oxidant barrier; - auto-healing of any micro-fissures exposed to contact with fluids, thanks to the particular crystallising additives; - increment of durability of the structures repaired with Rinfor Grout Col, thanks to the migration effect of the crystallising additives; - very high resistance to fire; - eco-sustainability - made up of 100% mineral and metallic materials, totally recyclable at end of life. From the environmental point of view, the Rinfor Grout Col product is characterised by the following advantages: - Ecological packaging (card-cardboard) - product based on hydraulic binders, selected aggregates and mineral additives with content of organic raw materials < 1% - practically nil VOC emissions during installation; once hardened, nil VOC emissions. - containing a fraction > 5% of sub-products from the production industry 100% recyclable at end of life. For seismic adaptation with absorption and transfer of pressure or traction during events with elevated dynamic forces (seismic, impacts, deflagration); - for structural reinforcing and seismic upgrading through coating of beams, pillars structural ties, walls; - for reinforcing and seismic upgrading with external, low thickness, structural screed for lofts in reinforced concrete, concrete masonry, corrugated sheeting, wood;
 - for fabrication of light, thin section, structural elements
; - for the repair of flooring with need for resistance against elevated static and dynamic stresses, together with exceptional values of resilience and resistance to impacts; - for reinforcing and precision anchoring of heavy and highly stressed machinery: E.g. wind turbines, turbines, precision machinery, etc. The support must be in good condition, clean, sufficiently coarse, without crumbling parts or dust, pressure washed and saturated with water before application. With concrete, the abrasiveness of the support must be > 3mm; to obtain this level of coarseness, techniques of hydro-scarifying, bush-hammering, mechanical chiselling, sand blasting with large grain may be considered. With the case of surfaces in strongly absorbent brick-work (lofts in brick cement with surfacing of parts in brick) or in the case in which it is impossible to saturate the support with water, contact our technical services to evaluate suitable adhesion primers, such as Syntech Pavisheer or Syntech RGS. Above all, when used as a surface covering of lofts in concrete, or as a repair to industrial flooring, providing anchoring roots by drilling the support is particularly useful for increasing resistance to cuts and adhesion to the support (diameter 18-20 mm, depth 20 mm), and accurately cleaning the surfaces of the holes before spreading the Rinfor Grout Col.
