Cementitious Materials; Advanced Performance

Repair mortar on substrate (enlarged picture)

In conjunction with questions related to concrete technology, we focus on two core areas. The first one is the valuation of new concrete raw materials (e.g. cement, additive, admixtures) and their application in new mix designs, putting special emphasis on rheology of cementitious systems. The second main focus is concrete maintenance and repair. Here new mix designs, special fields of applications as well as influences of application conditions are examined.
