Definitions
- the present disclosure relates to concrete compositions and, more particularly, to geopolymer compositions and method for making same.
- Geopolymers have been investigated and developed as an alternative to standard hydraulic cements such as Portland cement. Geopolymers provide many environmental advantages to traditional cements, for example having a smaller carbon footprint by producing approximately 0.25 tonnes of carbon dioxide per tonne of geopolymer produced where traditional cements produce up to 1 tonne of carbon dioxide per tonne of cement produced. In addition,
- geopolymers may be formed from waste streams from industrial processes, such as fly ash or blast-furnace slag.
- geopolymer compositions formed from aluminosilicate materials, Portland cement and an alkali metal silicate in a predetermined ratio with the Portland cement. It is an advantage of the geopolymer compositions disclosed herein that the ratio of Portland cement to alkali metal silicate can be selected to provided predetermined advantageous properties of the geopolymer composition. It is a further advantage of the geopolymer compositions disclosed herein that, upon addition of the alkali metal silicate to a slurry comprising an aluminosilicate material, Portland cement and water, a phase change occurs providing a low viscosity liquid mixture that is self compacting and self-levelling prior to the onset of setting of the geopolymer composition. In addition, a flowable slurry can be formed from the aluminosilicate material, Portland cement and water, which can then be activated as required by the addition of the alkali metal silicate to initiate the geopolymerisation reaction.
- a geopolymer composition comprising the reaction product of a reaction mixture comprising:
- aluminosilicate material 30-80% w/w aluminosilicate material, the aluminosilicate material having a combined AI2O3 and S1O2 content of from 15-90% w/w;
- alkali metal silicate 1-10% w/w alkali metal silicate, wherein the Portland cement: alkali metal silicate ratio is in the range from about 0.1 to about 3.0.
- the aluminosilicate material is not particularly limited and may be, for example, selected from the group consisting of: fly ash, metakaolin, blast furnace slag, perlite, red mud, ferronickel slag, volcanic ash, and combinations thereof.
- the aluminosilicate material comprises less than 10% w/w calcium oxide, more preferably less than 7% w/w calcium oxide.
- the aluminosilicate material comprises Class F fly ash.
