A CO₂ sensor was acquired through the SPP 2436 coordination project to support experimental research across participating projects. The sensor measures CO₂ concentrations in air up to 20% using non-dispersive infrared (NDIR) technology and includes automatic temperature and air-pressure compensation. It can be used for monitoring CO₂ concentrations and uptake processes in carbonizable materials and cementitious systems.

A common calcined clay reference material was prepared and processed for use across the SPP 2436 projects. The coordination project funded the grinding and preparation of approximately 1.5 tonnes of material to ensure consistent material availability and comparability between participating research projects.
