REDOL - Aragon's REgional Hub for circularity: Demonstration Of Local industrial-urban symbiosis initiatives
Redol deals with closing material cycles using the city of Zaragoza as an example. The research project focuses on solid urban waste, which is an abundant source to produce circular products. Five value chains for solid urban waste in the Aragon region will be redesigned in order to be able to produce circular products using an industrial-urban symbiosis approach.

Cements of the Future 2025
With the decarbonisation of cement production and the expected reduction in blastfurnace slag and fly ash quantities, unburned limestone, calcined clays, and recycled fines will gain in importance as cement main constituents. The focus will be on new, clinker-effcient cement types such as CEM II/C and CEM VI cements, whose performance allows a wide range of applications in practice. This online seminar provides an overview of the current state of development and standardisation of new cements. The possibilities and limits for practical implementation will be presented.

Fresh concrete properties and hardening behaviour of concretes with clinker-efficient cements CEM II/C and CEM VI
EN 197-5 defined the clinker-efficient cements CEM II/C and CEM VI. Technical approvals for the application of CEM II/C cements have been issued. For a widespread application, it is important that all parties involved develop confidence in the new products. With new findings on fresh concrete properties, hardening behaviour and durability two research projects of the VDZ Concrete Technology Department will provide an important basis for application of these cements in concrete for the construction industry.

Durability of concrete
Participants will get a comprehensive overview of concepts for ensuring the durability of concrete structures. In addition to the damage mechanisms the concrete technology and design elements as well as the execution are explained. On the basis of examples the influence of the cement on durability-relevant parameters is going to be explained. Performance concepts and the principles of service life design are also addressed. For the participants it is possible to discuss their current issues from operational practice.

Recycled clay brick containing materials as a raw material in resource efficient cements and durable concretes
The topic of the research project is the utilisation of brick-containing materials from the recycling of mineral construction waste. It is being investigated whether and how resource-efficient cements can be produced with processed brick-containing construction waste and reduced clinker content, thus reducing process-related CO₂ emissions.
