Performance of material tests according to standards and individual customer requirements (e.g. as function of temperature and humidity)

Chemical analysing methods (according to standards or laboratory regulations)

  • Sampling, sample conditioning, preparation, preconcentration, digestion, and separations for the determination of elements, cations, and anions among others
  • Gravimetry, complexometry, potentiometry, chromatography, conductometry, and photometry
  • General chemical tests, including pH value, conductivity, loss on drying, loss on ignition
  • Simultaneous ICP-OES multi-element determination, e.g. for the characterization of silicate matrices, eluates, heavy metals, sewage sludge, soil, sediments, waste, cement, lime, and gypsum analysis as well as analysis of aggregates, additives, fly ash, industrial waste by-products, and analytics of additives such as Na2O, K2O, Cl
  • Determination of water soluble salts
  • Characterization of efflorescence and corrosion products
  • Halogen and sulphur determination in organic matrices
  • Determination of pozzolanic reactivity of mineral solids according to Chapelle

Material tests (according to standards or laboratory regulations)

  • Determination of characteristic properties (viscosity, yield point and strength, hydration reaction, setting and curing times) of binder suspensions and the influence of various additives
  • Determination of characteristic mechanical strength parameters (tensile, compressive, and flexural strength) of mortars, concretes, plastics, metals, and other building materials, also as function of temperature
  • Determination of load-dependent and load-independent deformation characteristics of material systems (modulus of elasticity, creep, shrinkage, etc.)
  • Characterization of the durability of building materials (e.g. resistance of coatings against rising damp, aging resistance of plastics, material stability, resistance against alternating climatic changes, chloride penetration, water absorption, etc.)
  • Surface and adhesive strength tests
  • Determination of the glass transition temperature of plastics

Characterization of materials by means of:

  • Computed tomography
  • Spectrometry, e.g. FTIR
  • Differential scanning calorimetry
  • Tensiometry
  • Ion chromatography
