4. Conclusions
In this investigation, eight geopolymer mortars mixtures incorporating
sustainable binders such as FA and POFA were prepared.
The tests included microstructural analysis of XRF, XRD, FESEM
and FTIR to study the feasibility of replacement of POFA in FA
based geopolymer mortar. The compressive strength of the mortars
was investigated for a period of 112 days. Based on the tests
conducted, the following conclusions were drawn:
