Fly ash geopolymer mortar: Impact of the substitution

2021-1-10  The minimum compressive strength of fly ash geopolymer mortar prepared using river sand at RT is 18 ± 1 MPa and it increases up to 29 ± 1 MPa when copper slag is used as the fine aggregate (see Fig. 2). The compressive strength also increases when the binder to fine aggregate (B/FA) ratio is increased from 1:1 to 1:2 in both the cases.

The properties of fly ash based geopolymer mortars

2016-2-15  This paper reports the properties of fly ash based geopolymer mortars made with dune sand. The geopolymer mortars of different cation type, namely sodium based (Na), potassium based (K) and a mixed Na/K, were prepared with dune sand (DS) and river sand (RS). The corresponding geopolymer pastes were also prepared.
