In the context of the pressure to reduce the production of CO2 emissions in cement manufacturing, cement plants are significantly changing their product portfolios. Changes in the composition of cement products also lead to changes in their properties. This paper focuses on the monitoring and non-standard evaluation of initial volume stability. Several different types of currently used cements produced in various cement plants in the Czech Republic and Slovakia in 2022 and 2023 were tested using the -initial volum...

One of the main monitored parameters related to road traffic safety is the visibility of road facilities and how they are perceived by drivers. Areas where visibility is suddenly limited, or where road sections become unclear due to inadequate design and technological arrangements, pose significant safety risks. Monitoring the optical properties of the applied coating surface, particularly its retroreflection and colour, is crucial for traffic safety. The paper describes research leading to the design of a system ...
