ZM-23 Masonry mixture for gas silicate blocks of unstable geometry

Masonry mixtures

Thin-layer masonry mortar, manufactured industrially in the form of a dry mixture with mineral binding fillers and modifying agents. After mixing with water forms a homogeneous adhesive mass of grey colour. Suitable for interior and exterior use.

Use of ZM-23 masonry mixture for gas silicate blocks

Masonry mixture designed for construction of exterior and interior walls made of cellular concrete blocks (for example - aerated concrete), connected by thin seams. The solution is also suitable for the laying of walls made of sand-lime blocks (silicate). Furthermore, it can be used inside buildings for leveling and smoothing of walls made of blocks.

Technical data:

  • Composition: Portland cement, mineral fillers, modifying additives
  • Aggregate size: from 0 to 0,5mm
  • Ultimate strength: ≥ 10 MPa
  • Reaction to fire: class A1
  • Seam strength (table value): ≥ 0,30 MPa
  • Ultimate flexural strength: not more than 40%
  • Water absorption: ≤ 0,5 mm
  • Heat transfer coefficient λ: 0,47W / m * K≤ 0,1% Cl
  • Weight loss after 25 cycles: not more than 5%
  • Package: 25 kg bags
  • Storage: up to 12 months from the manufacturing date in a dry place in original sealed packages

Operating temperature: from +5oC to +25oC

Seam thickness: from 1 to 3 mm

Suitability time:about 3 hours at the temperature of +20oC and air humidity of about 60% after mixing with water

Consumption: 12cm wide block — 3 kg/m2; 24cm wide block — 6kg/m2, 36cm wide block — 9kg/m2, for blocks with the “tongue and groove” system the consumption will be less than 20%
