GEOPOLYMER CEMENT - Torus Dome

Geopolymer Cement, a review; J. Davidovits 2 1. Introduction From a terminological point of view, geopolymer cement [1] 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.

Geopolymer cement - Wikipedia

Geopolymer cements can be formulated to cure more rapidly than Portland-based cements; some mixes gain most of their ultimate strength within 24 hours. However, they must also set slowly enough that they can be mixed at a batch plant, either for precasting or delivery in a concrete mixer.

Production. Production of geopolymer cement requires an aluminosilicate precursor material such as metakaolin or fly ash, a user-friendly alkaline reagent (for example, sodium or potassium soluble silicates with a molar ratio MR SiO 2:M 2 O ≥ 1.65, M being Na or K) and water (See the definition for "user-friendly" reagent below).

Sustainable Building Materials - Geopolymer Concrete

Geopolymer concrete used as a structural mortar in 3-D concrete printing is superior to a Portland-based mortar since the Geopolymer will chemically fuse together, while the Portland based cement will have a tendency to create a cold joint. For these facts Geopolymer is incomparable to any other medium for stability and strength in 3-D printing.
