Geopolymer Cements
There is often confusion between the meanings of the two terms geopolymer cement and geopolymer concrete. A cement is a binder whereas concrete is the composite material resulting from the addition of cement to stone aggregates. In other words, to produce concrete one purchases cement (generally portland cement or geopolymer cement) and adds it to the concrete batch.
Geopolymer cement is sometimes mixed up with alkali-activated cement and concrete. Despite more than 50 years of application in Eastern Europe after the development by G.V. Glukhovsky, alkali-activated materials are not sold to third parties as commercial cement. They are simply 'alkali-activated concretes'. On the contrary, geopolymer chemistry was from the start aimed at manufacturing binders and cements for various types of applications. For example the British company banah UK (http://www.banahuk.co.uk) sells its banah-Cem™ as geopolymer cement, whereas the Australian company Zeobond (http://www.zeobond.com) markets its E-crete™ as geopolymer concrete (not cement).
From a terminological point of view, cement is a binding system that hardens at room temperature, like regular portland cement. If a geopolymer compound requires heat setting it may not be called geopolymer cement but rather geopolymer binder.
