Concrete without cement
Geopolymer Concrete for the Precast Construction
The use of alkali activated binder systems becomes increasingly important in concrete technology. Besides the ecological aspects, especially the reduction of the CO2 emissions when producing the binders, the improvement of special concrete properties which is achieved by using these binder systems is gaining importance. Alkali activated binders with lower calcium contents are often also called “geopolymers”. The reactions of the geopolymer binder system required for strength formation differ significantly from the reactions already known from the systems based on Ordinary Portland Cement...
