The Einscan HX mobile handheld laser scanner enables the digital capture of objects with a resolution of up to 0.05 mm. The scans can then be used to create 3D models for comparing the target/actual geometry of printed objects or reverse engineering, for example.
3D plastic printer with Fused Deposition Modelling (FDM) technology and a build volume of 223 x 220 x 205 mm. Compatible with filament diameters of 2.85 mm.
As many as 3 adiabatic and 4 semi-adiabatic calorimeters are available for determining the temperature increase due to the heat of hydration released during cement hydration.
The rheometer measures the deformations of the material (e.g. cement suspension) under the influence of the load entered in the shear profile. Rheological properties can be determined from the data obtained.
By means of the CNC portal milling machine (computer numerical control), components made of a wide variety of materials (aluminium, plastic, wood, polystyrene) can be produced with a high degree of precision.
The “Digital Construction Site” stands out as a unique and large-scale research infrastructure, offering an environment to explore digital technologies within authentic construction site conditions. This application-focused and adaptable research facility opens up exceptional new opportunities for investigating the potential of a digital and integrated design and production process. The infrastructure comprises a gantry system featuring a fully-automated mixing plant designed for the 3D printing of 1:1-scale building components. Additionally, it includes a mobile robotic unit for collaborative digital construction processes, along with testing and measurement equipment for on-site material characterization and component analysis. The “Digital Construction Site” is a collaborative effort involving the Institute for Construction Engineering and Management (ibb), the Institute of Geodesy and Photogrammetry (IGP), the Institute of Structural Design (ITE), and the Institute of Building Materials, Concrete Structures and Fire Safety (iBMB).
By means of digital image correlation, movements and deformations can be captured optically and thereby contact-free, which allows conclusions to be drawn about e.g. strains, stresses and consequently also material characteristics.
Dynamic flow curve: characterization of the basic rheological flow properties of fresh concrete: yield stress and plastic viscosity (Bingham parameters)
Maximum possible aggregate grain size to measure: up to 32 mm
Isothermal heat flow calorimetry enables a time-resolved investigation of cement hydration. Endothermic or exothermic reactions lead to a temperature change in the sample, which is converted into a heat flow signal.
By means of the climatic test chamber, different environmental conditions (temperature, humidity and carbon dioxide content) can be conveniently simulated.
The NMR-MOUSE is a non-destructive sensor that combines the strengths of time-domain NMR with microscopic spatial resolution. Due to its compact size, the system is portable, and the open sensor geometry allows the measurement of spin densities, relaxation times, and self-diffusion coefficients. This allows measurements for monitoring water transport in dynamic processes, such as water absorption or drying in concrete samples.
With the injector blast cabinet, surfaces can be specifically reworked, e.g. the cleaning off of non-activated particles from printed objects from selective cement activation or the roughening of concrete surfaces for the subsequent application of repair measures. The blasting material used can be reused via a recovery system
The microTrac helium pycnometer is a measuring device for material characterisation with regard to volume and density determination. The helium pycnometry method is used to determine the real density of porous solids and powders.
The Baubot is a fully mobile robot system consisting of a fully electric heavy-duty crawler platform and a 6-axis industrial robot. The Baubot therefore offers a wide range of possible uses.
The Particle Track probe-based instrument with Focussed Beam Reflectance Measurement (FBRM) technology enables continuous analysis of particle size distribution, number and shape. The probe can be used in suspensions with high solids concentration.
With the particle bed laboratory printer from Progress AG, building components can be additively manufactured with a high degree of freedom of shape using Selective Cement Activation (SCA). Cement hydration is controlled locally by applying water to a particle bed consisting of cement and fine aggregate. The construction box measures 0.7 m x 0.35 m x 0.5 m (l x w x h).
SAMMI is a test setup for the field of additive manufacturing with concrete. It was introduced as a small-scale test setup for the Digital Building Fabrication Laboratoy (DBFL).
