Repar Steel Two-component cement slurry, modified with flexibilising resins and specific anticorrosive agents for the passivating treatment of oxidised reinforcement rods, in the restoration of degraded concrete. The anticorrosive efficacy of Repar Steel is determined by the high alkalinity and by the superpozzolanic reaction of the components of the anhydrous system, as well as by the presence, in the liquid component (B), of migratory and interfacial corrosion inhibitors, capable of carrying out cathodic and anodic protection, based on organic compounds capable of making ferrous ions unavailable for feeding electrochemical corrosion processes. The polymeric components of the solution also determine further increases in the anticorrosive efficacy, especially against aggressive attacks deriving from chlorides and sulphates, and increase the adhesion between the treated bar and the concrete (adherence test according to EN 15184 in compliance with the UNI EN technical standard 1504 "Products and systems for the protection and repair of concrete structures - Part 7: Corrosion protection of reinforcements"). Passivating protective anti-corrosive treatment for reinforcing rods in restoration works in reinforced concrete. Carefully remove loose rust from the metal surfaces of exposed reinforcing bars by sandblasting or deep brushing until the white metal surface is obtained. This operation is essential to effectively develop the anticorrosive property of Repar Steel. Obviously, to block the advance of the carbonation profile in the concrete, it is essential to complete the restoration with the appropriate restoration mortars: thixotropic (Repar line) or pourable (Grout line). Mix components A and B and continue mixing until a homogeneous, lump-free mixture is obtained. Apply with a brush to the surfaces of the previously prepared reinforcing bars. To prevent the application of the repair mortar from removing the still fresh Repar Steel treatment, wait for the product to harden before proceeding with the volumetric restoration. The minimum recommended waiting time is approximately 6-8 hours with summer temperatures and approximately 12-16 hours with winter temperatures. Do not apply the product with temperatures below 5°C or if it is expected that the temperature may fall below this value during the first 12 hours of curing. From 0.03 to 0.1 kg of Repar Steel for each linear metre of steel bar to be treated. Pail 3.4 kg [A] - Bottle 1.6 kg [B] - Kit: 1 Pail 3.4 kg [A] + 1 Bottle 1.6 kg [B]

Readymesh MM-150 Fibres, obtained by the cutting of steel wire, with improved adhesion profile, for three-dimensional general structural reinforcement of cement-based conglomerates. The addition of Readymesh MM-150 significantly increases the mechanical performance of the structure in terms of toughness, ductility, fatigue, dynamic stress, shock, wear, tensile and shear strength and even post-cracking and damage behaviour. Readymesh MM-150 are particularly recommended for increasing ductility, toughness and thermal conductivity in concrete coatings for floor heating systems. General preparation of screeds, cements and fibre-reinforced concrete. Particularly recommended for compact prefabrications, thin concrete floorings and radiant floor heating systems. "Readymesh MM-150 fibres must be added to the concrete during mixing. It is recommended to pour the fibres directly onto the loading belt of the concrete mixer during the loading of the aggregates. Alternatively, it is possible to add them directly into the mixer after loading the concrete or into the onsite mixer. In this case, extend the mixing time by at least one minute (after a minimum of 3 minutes) for every m³ of packaged concrete in order to achieve optimal distribution. If using a 200-litre onsite mixer, add the fibres immediately after loading part of the aggregates and before adding the remaining parts. The typical dosage of Readymesh MM-150 fibres varies from 15 to 30kg/m³. Conglomerates with Readymesh MM-150 can be easily transported and used with pumps, joiners, vibratory finishing machines, roadway extruders (e.g. slipform paver), etc. These fibres are typically used in conglomerates that have an aggregate diameter not exceeding 10-15mm."

Readymesh MX-500 Readymesh MX-500 is a special carbon steel fibre, obtained by the extrusion and cutting of high-strength steel wire. Its special double-hooked form gives it a remarkable shear strength, thus conferring the concrete with excellent post-cracking structural strength even at low doses. Readymesh MX-500 significantly increases the mechanical performance of the structure in terms of toughness, ductility, fatigue, dynamic stress, shock, wear, tensile and shear strength and even post-cracking and damage behaviour. General preparation of fibre-reinforced concrete with high pre and post-cracking performance. Ideal for industrial flooring and prefabrications. "Readymesh MX-500 fibres must be added to the concrete during mixing. It is recommended to pour the fibres directly onto the loading belt of the concrete mixer during the loading of the aggregates. Alternatively, it is possible to add them directly into the mixer after loading the concrete. In this case, add the fibres a little at a time so that they are well-distributed in the cement mix and extend the mixing time by at least one minute for every 20 kg of fibres added in order to achieve optimal distribution. Conglomerates with Readymesh MX-500 can be easily transported and used with pumps, joiners, vibratory finishing machines, roadway extruders (e.g. slipform paver), etc." Variable according to the type of work to be carried out and/or performance to be achieved.

Helix steel aisi Helical bar in AISI 304 stainless steel, cold drawn, with high mechanical performance, for the reinforced styling of joints and for connections, including through-holes, on masonry, reinforced concrete, arches and vaults. Suitable for the consolidation of structures in seismic areas; advantageous in combination with hydraulic binders (cement and hydraulic lime) and with resin matrix binders, it particularly facilitates the achievement of physical and mechanical performances in combination with Unisan mortar, with those of the REPAR, GROUT family and with the structural resins of the SYNTECH family. The optional accessory Connector Steel Aisi 304, supplied separately on request, allows the connection between the passing helical bar and the helical bar positioned deeply on the stripped joint. Helix Steel AISI 304 bars are available in a range of diameters: 6, 8, 10 or 12 mm, all characterised by their durability even in aggressive environments, their high tensile and shear strength, and excellent flexibility. Such characteristics make the use of these bars particularly advantageous in combination with hydraulic binders (cement, hydraulic lime), air binders (air lime) and resinous matrix binders. Flexibility, handling and versatility with various binder matrices, permit the realisation of rapid, non-invasive reinforcement operations, being easy to apply and with low installation costs. Very high mechanical physical benefits come when combined with our mortars of the REPAR, GROUT and Unisan lines and the structural resins of the SYNTECH line. Reinforcement operations on concrete and masonry structures. Reinforced pointing of joints. Structural one-sided connections or through-holes crossing the entire section. Helical morphology allows optimal gripping on bricks, mortars, stones and on old walls of historical and cultural interest generally. The durability against atmospheric and environmental conditioning makes the use of Helix Steel AISI 304 bars particularly advantageous in the structures affected by the presence of aggressive soluble salts (sulphates, nitrates, phosphates). Reinforced pointing of joints: Deep stripping of joints can ensure the placement of the bar at a depth of a few centimetres from the surface. To remove any loose and crumbly parts (stone, bricks, enticing mortar, etc.). Cleaning and saturation of the substrate with pressure washing. To remove any saline efflorescence by brushing or sandblasting. Connections on masonry, concrete, arches and vaults: Make sure that there are no loose or crumbly parts on the substrate. Stripping of mortar joints. Cleaning and saturation of the substrate with pressure washing. To remove any saline efflorescence by brushing or sandblasting. Reinforced pointing of joints: Reinforced pointing of masonry joints by filling part of the joint profile with an initial layer of Unisan fibre-reinforced composite mortar (see the data sheet), then on the mortar whilst still wet, inserting the Helix Steel AISI 304 bar before covering with a final layer of Unisan mortar. Press the mortar inside the joint, being sure to press well until totally full and flush with the wall. The temperature of the substrate must be between +5° and +35° C. Connections on masonry, concrete, arches and vaults: After carefully preparing the substrate and before applying the first layer of structural mortar (lime- or cement-based depending on the type of operation), wet with water at low pressure until complete saturation, bearing in mind that a lack of saturation may prevent adhesion and cause cracking in the mortar. If necessary, apply a rough coat of Untersana mortar. Proceed with creating holes of a suitable diameter and inclination (at 45° if the operation is undertaken only on one side of the structural element). Before they are bent in anticipation of the mesh, the connectors emerge from the substrate by at least 10–15 centimetres from flush with the wall. Apply an initial coat of Unisan fibre-reinforced composite mortar (see the technical data sheet) by hand (with stainless steel trowel or putty knife) or with a plastering machine to achieve a thickness of about 1.5 centimetres, leaving the surface sufficiently rough to facilitate the adhesion of the subsequent layer. Alternatively, depending on the structural requirements, mortars of the REPAR line can be used. Place the primed alkaline-resistant fibreglass mesh of the ARMAGLASS STUCTURA line (see the technical data sheet of the selected product), placing it on the still-fresh mortar by passing the Helix Steel AISI 304 connector between the bars of the mesh. After bending the connector, restraining the mesh, apply a second finishing layer of mortar (Unisan or REPAR) at a thickness of about 1.5 centimetres. Product to be purchased as needed.
