Analysis of "Glue Mortar" type adhesives

The adhesive mortar includes the family of adhesive mortars intended for bonding a coating such as tiling, paving and certain masonry blocks (Siporex cellular concrete, BA13 plaster panels, plaster tiles, etc.). They generally consist of an inorganic matrix (sand, plaster, mineral filler, etc.), a polymeric matrix in the form of a resin or hydraulic binder to strengthen adhesion and additives.

Study of the composition of an adhesive mortar material

It is possible to perform structural analyzes by Pyrolysis/GCMS and IRTF to study the nature of the polymer matrix.

  • The adjuvants can be analyzed after solid / liquid extraction by GCMS and UPLC/TOF-MS.
  • The enthalpy and the polymerization temperatures as well as the glass transition temperature (Tg) can be obtained by thermal analysis by DSC.
  • Elemental analysis by SEM/EDX electron microscopy will allow dimensioning and determination of the nature of any charges.
  • Thermal analysis by TGA will give the contents of volatile fraction, polymer and residual charge.
