Composition of this alkaline ettringitic cement
An innovative binder, H-EVA is an alkaline ettringitic technology.
Activators and superactivators formulated by Hoffmann Green are added to flashed clay, mixed with gypsum/desulfogypsum to obtain H-EVA cement. Gypsum from industrial processes, such as desulfogypsum or phosphogypsum, are currently still little upgraded.
H-EVA is ideal as a road binder, but also for mortars, plasters and construction concretes.
