Characterization of concrete components
- Cement, admixtures, ultrafine particles, aggregates, fibers, ...
- Determination of a material's organic matter content by weight (granulometric analysis by sieving and granulolaser).
Small- and large-scale measurements on fresh concrete
These measurements can be carried out on small or large volumes of 600L:
- Superplasticizer vs. cement compatibility,
- Rheological measurements with a Rheometer for cement paste and concrete.
- Rheology of 3D printed mortars
- Measurement of the percentage of occluded air,
- Consistency tests,
- Endogenous shrinkage measurement,
- Strength measurements,
- Water requirement and consistency control,
- Determination of setting times,
- Calorimeter
Measurement on hardened concrete
These measurements can be carried out on small or large volumes of 600L:
