Recycling and Sustainable Materials

Construction Chemistry, Building in Existing Structures, Recycling and Sustainable Materials

Prof. Dr.-Ing. Andrea Kustermann

The research field Construction Chemistry, Building in Existing Structures, Recycling and Sustainable Materials is supervised by Prof. Dr. Andrea Kustermann.

The research work focuses on concrete technology, damage reactions of building materials, sustainable building materials and dismantlable constructions.

Main topics in concrete technology are microcracks in concrete, high-strength concrete, fiber concrete, high-strength fiber concrete under highly dynamic loading, lightweight concrete, recycling concrete, basalt as reinforcement in the field of repair, building material use and concrete technology in the context of ressource conservation.

Specific current research topics include:

• life cycle assessment of concrete and concrete with recycled aggregate (linear and circular economic system) considering different transport processes
• development and research on durability properties and also first applications of Recycling Concrete using 100% recycled aggregate
• use of alternative reinforcement methods such as basalt reinforcement
• investigations on treated recycled sand as supplementary cement material
• use of ultra-high-strength or high-performance concrete for repair work
• development of a guideline for the dismantling and recycling of single-familyhomes in prefabricated timber constructions
• implementing recycled aggregates in mortar for compressive materials
• determination of chlorides in concrete with X-Ray Fluoreszenz Analyzer
• development of durable bridge caps resource saving freeze resistant with basalte fibre reinforcement with recycling concrete
• application of microbial induced precipitation (MICP) for building materials and structures (Microbialcrete)
