We conduct leading research, development and consultancy in the field of innovative and sustainable construction materials and technologies.
Development of Construction Materials
Optimization │ Setting time │ Development │ Lime │ Cement │ Puzzolanes │ Anhydrite │ Gypsum
We test and develop construction materials in accordance with DIN standards, optimize them and adjust their composition to special demands. Our core competences are:
- Gypsum / anhydrite based materials (self-leveling floating screeds, mortars, plaster, render)
- Lime, natural hydraulic lime for mortars, renders, plaster
- Cement based materials (alone or in combination with fly ashes, slags etc.) for special applications (tunnel grouting, shaft sealing, bulkhead constructions, rock grouting etc.)
- Development of backfill materials, including encapsulation of contaminants
The following services are offered:
- Determination of flowability, setting time, viscosity
- Determination of the mechanical properties (compressive / bending tensile strength etc.)
- Optimization of the water / binder ratio
- Determination of frost and thaw resistance
- Determination of capillarity and water retention
- Determination of water contents by CM (calcium carbide) method
- Determination of the thermal degradation behavior (DTA/TG measurements)
- Fresh mortar characterization
- Determination of adhesive pull strength
- Particle size determinations by sieving or measuring with Coulter Laser Diffraction Particle Size Analyzer LS13320
- Ultrasonic testing of all types of construction materials
- Determination of shrinkage and swelling and swelling pressure
We have many years of experiences in all services and offer also on-site quality control as well as special, nonstandard measurements (swelling pressure, permeability measurements etc.).
