Concrete and its constituents
- properties of lightweight, normal-weight and heavy-weight concrete

- concrete additives and admixtures
- cements
- steel and polymer fibres for concrete
- natural stone and aggregates
- hydrophobising agents
- rheology of cement grouts
- total porosity and porosity distribution
- microstructure observations using classic and electron microscopy
Soil and geosynthetics
We identify the following:
- physical properties (granulometric composition, humidity, consistency limits, linear shrinkage, total specific area and sorption volume, specific density, volumetric density)
- maximum and minimum bulk density
- organic matter content
- optimum water content and maximum dry density (Proctor apparatus)
- consolidation and compressibility parameters
- swelling pressure and swelling index
- coefficient of permeability
- strength parameters (shear strength, coherence and internal friction angle in a direct shear apparatus, using the UU method of tri-axial compression without consolidation and drainage, and CU and CD methods, with saturation and consolidation, residual strength, determination of the shear modulus based on the measurement of the speed of acoustic waves and probe-mounted sensors)
- water permeability in a vertical direction to the product surface
- water flow capacity in the product plane
- index flux
- characteristic pore size
- long-term protective efficacy of geotextiles in contact with geosynthetic barriers
