Laterlite MX-R4 - Ремонтный раствор и затирка для ремонта

RureGrout R4 MC is a ready-mixed mortar based on cement, selected aggregates with a maximum diameter of 3 mm, additives, shrinkage control agents in the plastic phase and hardened phase, polyacronitrile fibres and inorganic fibres with a length of 12 mm, diameter 14 tensile strength 1700 MPa and elastic modulus 72 GPa.‎ After the addition of water, a fluid mortar is obtained that is highly adhesive to concrete and steel.‎ RureGrout R4 MC is suitable for the restoration and reconstruction of large concrete structures by casting.‎ It is a ready-to-use material, in fact only water needs to be added to obtain a fluid material to be cast into formwork in thicknesses up to 50 mm.‎ For filler thicknesses greater than 50 mm, add clean aggregate (with a grain size of 4-8 mm), equal to 25%-35% of the weight of RureGrout R4 MC powder (25-35 kg of aggregates for every 4 bags of RureGrout R4 MC).‎ For a surface finish that enhances the aesthetic character of the intervention while increasing its durability, proceed with the application of one of the protective systems.‎ Compressive strength at 28 days (UNI EN 12190) > 65 MPa Flexural strength at 28 days (UNI EN 196-0) > 10 MPa Elastic modulus at 28 days (UNI EN 13295) > 28 GPa Adhesion to concrete (UNI EN 1542) > 2 MPa Opposed expansion in air 24 h (UNI 8147) > 400 µm/m Fields of use Restoration and reconstruction of reinforced concrete pillars and beams.‎ Restoration and reconstruction of motorway, road and railway viaducts.‎ Restoration of the lower bulbs of prestressed beams in infrastructure.‎ Restoration of concrete floors (industrial, road and airport).‎ Restoration of hydraulic structures.‎ Filling of rigid joints between concrete elements.‎
