Synthetic resin-bound
and polymer-modified building materials
The investigations at polymer-modified
mortars (fresh and hardened mortars) essentially
correspond to those, which are specified under investigations of/at
mortars and plasters.
Additions:
- determination of the wear resistance
according Böhme
- durability investigations
- resistance against
most different chemicals
(procedures according Franke/Fricke; Koch/Steinegger)
- physical durability
(freeze de-icing salt resistance, freeze-thaw cycles resistance)
- determination of the content
of polymers
Basic materials
- grading curve
- solid content at
a temperature of 105 °C
- thermogravimetry
- infrared spectrophotometry
- total content of halogens
- pot life (processing time)
- consistency
- stiffness
- bulk density
- air content
- size distribution of particles
of synthetic resin emulsions

- determination of the kind of binders
by means of infrared spectrophotometry
- shrinking
- bulk density, flexural tensile, compressive
and tensile strength
- dynamic elastic modulus
- thermal expansion
- stability in calcium hydroxide solution
- water vapor diffusion coefficient
- water absorption
- evaluation of the bond
by means of
- lattice cut test
- adhesive strength test
- evaluation of the durability/aging
(storage with changing climate, UV resistance)
- measurements of the thickness and the structure of layers
by means of microscopy
- investigations of the structure
