Armaglass Structura 66 : Monolithic, preformed, glass fiber mesh, 66x66 mm mesh

Armaglass Structura 66 Monolithic GFRP mesh made with glass yarn bars and pultruded epoxy resin. The bars are intertwined with each other through a stitching thread, using a unique technology that allows the formation of joints between the longitudinal and transverse bars with high mechanical resistance. The epoxy resin guarantees the mesh high dimensional stability, alkali resistance and improves the mechanical characteristics. The composite has large square meshes, the size of which is ideal for use with CRM mortars. Armaglass Structura 66 combines lightness and reduced thickness with excellent mechanical characteristics in the warp and weft. It resists atmospheric agents and aggressive environments, giving durability to the composite systems in which it is used. Suitable for any support and perfectly compatible with both cement-based and lime-based mortars. Advantages: Easy installation Lightness, reduced thicknesses High mechanical performance Durability Stainless Radiolucency Zero electrical conductivity. The Armaglass Structura 66 fiberglass mesh, combined with our lime-based mortars (Intosana, Unisan) or cementitious (REPAR line) and Armaglass Connector GFRP connectors, is used for the reinforcement of masonry and concrete structures through the reinforced plaster technique (CRM system: Composite Reinforced Mortar). The mesh is a component of our RINFOR SYSTEM systems, which also include GFRP corners, gussets and connectors. The mesh can also be used as reinforcement for collaborating caps, screeds, restorations with structural mortars on reinforced concrete structures (tunnel linings, port quays, pillars, piles, etc.), especially when located in aggressive environments (marine aerosols, salts de-icers etc.). To prepare the support, carefully follow what is indicated in the technical data sheets of the mortar with which the Armaglass Structura 66 mesh is combined. For CRM reinforced plastering interventions: Cutting the net Unroll to the required length and preliminarily cut the mesh with a cutting hose with a diamond blade or tinsmith's shears. During the unrolling and handling of the rolls of net, be careful not to damage the net. Application of the CRM System Removal of existing plaster or concrete cover and all deteriorated parts. Saturate the support with low pressure water, apply if necessary (due to the conditions of the masonry, the type of mortar used or the thickness of the reinforcement) a rough coat of mortar, manually or with a plastering machine and leave the surface unfinished. Place the Armaglass Structura 66 mesh on the surface of the masonry to be reinforced. At the overlaps, overlap the mesh bands by at least 15 cm. GFRP Armaglass Connectors, with improved adhesion and 8mm diameter, are used as connection elements of the reinforcement system. Before installation, mark their arrangement on the support beforehand. Use a rotary drill to make holes with a diameter of 12 mm to house the connector (if working on one side only, the hole must be pushed deep to at least 2/3 of the thickness of the wall). Before inserting the connector into the hole, position the Armaglass Grid 66 GFRP distribution gusset which will be blocked against the mesh during the grouting phase of the connector. Carry out a thorough cleaning of the hole and grout the connector with chemical anchor (Syntech Profix or Syntech Fix EP). Proceed with spraying or throwing the mortar, in one or more hands. The mortar will entirely cover the GFRP elements with a total thickness according to the design documents. In order to guarantee the structural continuity of the reinforcement system in correspondence with all corner areas (openings, etc.), apply Armaglass Corner 66 GFRP corner piece. In case of intervention on both faces, two connectors will be inserted, one long and one short (the relative lengths must be chosen according to the thickness of the masonry). Make the 12 mm through hole. At the face where the short connector will be inserted and where the two connectors will overlap, enlarge the hole until reaching a total diameter of the hole equal to approximately 22-24 mm. The overlap between the connectors must be at least 11 cm long. After drilling the holes, carefully clean them with compressed air and inject chemical anchor based on Syntech Fix EP epoxy resin. Before inserting the connectors into the holes, always position GFRP Armaglass Grid 66 distribution gussets which will be blocked against the mesh during the grouting phase of the connectors. Proceed with spraying or throwing the mortar, in one or more hands. The mortar will entirely cover the GFRP elements with a total thickness according to the design documents. During the mortar curing phase, protect it from thermal stress and conditions of strong evaporation. It is always advisable to cure the mortar in a humid environment for at least 48-72 hours.
