Comparative Study on the Performance of Blended and Nonblended Fly Ash Geopolymer Composites as Durable Construction Materials

Table 2

Mix proportions of geopolymer mixes.

Sample ID	Fly ash (%)	Silica fume (%)	Borax (%)	K2O content in activator (%)	SiO2 content in activator (%)	Water (%)
SMF1	100	0	0	6	6	33
SMF2	100	0	0	6	0.6	33
SMS1	90	10	0	6	6	33
SMSB1	90	7.5	2.5	6	6	33
SMSB2	90	5.0	5.0	6	6	33
SMSB3	90	5.0	5.0	6	0.6	33

This is the percentage amount with respect to the total weight of fly ash, silica fume, and borax. Calculated as the % of (fly ash + silica fume + borax); measured by weight.
