Cement Investigations

Cement

  • Density (Pycnometer)
  • Grinding fineness according to DIN 1164, part 4 (air permeability device according to BLAINE)
  • Grain size analysis according to DIN 4188 (mesh analysis)
  • Grain size analysis with laser particle size granulometer LS13300
  • Residuals (insoluble) by oven drying according to DIN 1164, part 3

Cement slurry

  • Blending according to API Spec 10A (Waring Blender)
  • Free water loss according to API Spec 10A (Baroid filter press: Atm. (RT) & HPHT (Tmax=200 °C; pmax=4.2 MPa))
  • Flow behavior: apparent and plastic viscosity, flow boundary according to API Spec 10A (Fann-VG-Viscometer)
  • Flow time (Marsh funnel)
  • Consistency and setting time according to API Spec 10A (Halliburton Atm. and HPHT Consistometer)
  • HPHT expansion/dilation with ITE measuring device (Halliburton HPHT Consistometer: Tmax=180 °C; pmax=150 MPa)
  • Pressurized mud balance

Cured Cement

  • Compressive strength according to API Spec 10A (MAN hydraulic press: compressive force (F) up to 400 kN)
  • Tensile strength of cured cement sample
  • Shear strength of cured cement sample – using hydraulic press
  • Storage of various cement forms in an autoclave according to API Spec 10A (4 autoclaves: Tmax=180 °C; pmax=20 MPa; V=8000 cm³)
  • Thermal conductivity using the Solidtherm® method
