Online seminar concrete technology - have a deeper look

The online seminar, which is divided into six teaching units of 1.5 hours each, gives a well-founded overview of the verification concepts for ensuring the durability of concrete in various areas of application and on the subject of environmental product declarations (EPD). The speakers have excellent background knowledge and give tips, especially on questions that cannot be looked up in any textbook. The offer is supplemented by the opportunity to gain insights into the concrete technology online courses on the VDZ learning platform.

Seminar durability of concrete

The participants get a comprehensive overview of concepts for ensuring the durability of concrete structures. Based on the damage mechanisms, the concrete technological and planning elements are explained up to the execution. Using specific examples, the influence of the cement on parameters relevant to durability is highlighted. Performance concepts and the basics of service life measurement complete the picture. The opportunity is given to discuss current issues from operational practice together.

R-ZiEMENT: Recycled building materials containing bricks as raw material for resource-efficient cements in permanent concretes

The subject of the research project is the recovery of brick-containing materials from the recycling of mineral construction waste. It is investigated whether and how resource-efficient cements can be produced with processed brick-containing construction waste and a reduced proportion of clinker, thus reducing process-related CO₂ emissions.

LeptoCalc - Use of crushed concrete sands as the main cement component

The use of fines from concrete recycling plants as a cement component is currently only insufficiently investigated and requires further research. The basic requirement for the utilization of the fines will be to be able to characterize the material properties as quickly and comprehensively as possible and to ensure a constant flow of material. An essential part of the research project is therefore the development of a rapid test method with which the properties of these fines can be estimated by measuring the residual reactivity, among other things.
