Muro K M10

Class M10 structural mortar for plaster and masonry, based on natural hydraulic lime.

Structural concrete mix for consolidating and strengthening masonry, with high mechanical performance, high workability, thixotropy, plasticity and elasticity, controlled shrinkage, a low content of water-soluble salts, no reactivity with salts in the masonry and a very low VOC content. Based on NHL 3.5 natural hydraulic lime and pure selected aggregates with a maximum grain size of 3 mm, it is ideal for strengthening, securing, consolidating and seismically upgrading existing buildings, including listed buildings.

Key features:

  • contains no Portland cement;
  • contains no resins or organic additives that release VOCs;
  • class M10 according to EN 998-2;
  • class CS IV according to EN 998-1;
  • high mechanical performance, without being rigid;
  • adds no water-soluble salts to the masonry;
  • does not react with any sulfates in the masonry, so it is compatible with historic masonry;
  • breathable and hygroscopic, it prevents mold and condensation and regulates indoor humidity;
  • reversible and compatible with historic masonry.

Muro K M10 can be used as a plaster with or without reinforcing mesh, as a strengthening topping on vaults, or as a bedding mortar for solid brick, brick, sand-cement brick, mixed stone, tuff or calcarenite masonry.

The main applications are summarized below:

  • breathable scratch coat and/or plaster on stone or brick masonry;
  • consolidating scratch coat and/or plaster reinforced with metal, glass fiber or carbon fiber meshes properly connected to the wall face, on stone, tuff or brick masonry;
  • bedding of stone, tuff or solid brick masonry;
  • repairing cracks in stone, tuff or solid brick masonry by cuci-scuci, i.e. local dismantling and rebuilding of the masonry;
  • pointing joints in mixed stone, tuff or solid brick masonry;
  • strengthening of masonry joints, with or without reinforcement, in stone, tuff or solid brick masonry;
  • strengthening the extrados of solid brick or mixed stone vaults with a reinforced topping with metal, glass fiber or carbon fiber meshes properly connected to the vault;
  • full or partial leveling of the extrados of irregular vaults before consolidating them with steel, carbon fiber or glass fiber strengthening strips.
