Abstract:
The geopolymer technology has shown considerable good results for construction industry as an alternative binder to Portland cement. In construction industry applications a water resistant binder with sufficient strength is desirable. In addition the production technology necessitates an adequate processing time. Nevertheless after the shaping procedure the material should be demoulded immediately to enable feasible production. Therefore the binder should show a rather a late beginning of setting, but it should be possible to accelerate strength evolution when the material is shaped. The form of cementitious material using silicon and aluminum activated in a high alkali solution was developed. This material is usually based on fly ash as a source material and is termed geopolymer or alkali-activated fly ash cement. The mortar and concrete made from this geopolymer possess similar strength and appearance to those from ordinary Portland cement. Geopolymer exhibit many excellent properties such as high compressive strength, low creep, good acid resistance, low shrinkage, fire resistance and other mechanical properties. The work on geopolymer has been based on the normally used low calcium fly ash. Low calcium fly ash has been successfully used to manufacture geopolymer concrete when the silicon and aluminium oxides constituted about 80% by mass, with the Si-to Al ratio of about 2. It is also known that high calcium fly ash contains a reasonable amount of silica and alumina. This high calcium fly ash could also be suitable for use as base material for making geopolymer.
