ECOncrete – a sustainable binder, an alkali activated material, is based on
GGBS (fly ash could be added as well) with alkali activator which is a waste
material. Final strength is superior to any known cement, as well as durability
and shrinkage behaviour (cracking). Instead of dangrous and non sustainable
activators like alkaline solutions (NaOH, water glass etc) we have developed a
powder activator which is a waste material. Our powder activator is coming
from cement production. Moreover we could safely use also PCE
superplasticizer which could reduce water even greater than with OPC
cements.
