Our Services
Materials characterization:
Gas or glass pycnometer – true solids density (SG) Bulk density determination, Tapped and untapped density of bulk materials IR moisture-meter Liquid limit determination – cone penetration method (British standard) PSD distribution – sieves (wet and dry) PSD distribution – laser measurements pH measurements of water and paste Electric conductivity measurements ICP OS measurements (chemical analyze) Specific surface area determination by means of Blaine for binders and tailings XRD – mineralogical composition of aggregates (tailings) and binder XRF – chemical composition of minerals and binders Cement class determination (Standard mortar test)
Rheology testing:
Slump test (cylindrical and conical) Flow measurements with drop tables (spread) – static and dynamic. Yield stress measurements in rotational mode – control rate (HAAKE Viscotester IQ). Static and Dynamic. Viscosity measurements – Bingham plastic model for CPF. Flow retention measurements – oscillatory measurements (not distractive). Flow retention via yield stress measurements vs time. Ball penetration test
Hardening:
Early strength determination:
Time dependent setting and hardening process. by means of Rheometer/ oscillatory mode (Temperature control measurements). Vicat needle penetrometer. Temperature data loggers correlation to hydration process. Compressive strength testing with graphical presentation.
Final strength determination:
UCS with graphical presentation – uniaxial test EN 196. Shear box (in plan for 2022). E-modulus determination EN 13412. Tensile strength. Flexural strength determination.
