FoamLime Base

Description

FoamLime BASE mortar protects against outdoor weather and mechanical loads.

FoamLime BASE is a mortar manufactured from natural hydraulic Lime NHL-5 and high calcium content (CL-90-S) slaked or hydrated lime, both certified under UNE-EN 459-1:2010 Standard; siliceous and calcareous sands of great purity and compensated granulometries according with UNE-EN 12620, UNE-EN 13139, UNE-EN 13043 and UNE-EN 13242 Standards as well as from fibres and biodegradable additives

This mortar has exceptional qualities, which cannot be obtained in a natural way with cements or artificial limes, such as double setting.

This double setting comprises a first one, hydraulic and fast, due to the hydraulic lime content with which an immediate hardening is obtained on site, and a second, aerial and slow, as the result of carbonation produced by Carbon Dioxide pressure on slaked or hydrated lime.

FoamLime BASE properties

  • The hexagonal shape of the hydrated lime crystals provides higher plasticity.
  • The high fineness of hydrated lime (around 1 micron) as well as the aggregate content favours workability.
  • The larger specific surface of lime provides better workability and plasticity and the smaller particle size favours a greater coating of the aggregate.
  • It is compatible with the system and the other materials it is made up from, from a chemical, structural and mechanical point of view.
  • It has excellent adherence to the base substrate due to its lime fineness and water retention which maintains its alkaline pH (>12) longer.
  • Great elasticity which favours the adaptation to substrate deformations without producing cracks.
  • Constant volume under variable humidity conditions.
  • Provides aesthetic and homogeneous looks.
  • Less expansion and light shrinkage.
  • Higher flexibility under given mechanical conditions.
  • Does not produce efflorescence (white stains appear, produced by soluble alkaline salts—sodium and potassium sulphate) due to the fact that the lime it contains has been manufactured from high-quality raw materials and sodium and potassium content is below 0,01%, with an amount of soluble salts much lower than that of cement thus avoiding important damage to the stone/mortar system because of crystallization and/or hydration cycles.
  • Greater permeability—dampness is evacuated toward the exterior as vapour.
