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.

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.
