“…According to the requirements of the geopolymer preparing scheme, mix the water glass modulus which is 3.24 provided by the manufacturer and the dose of the sodium hydroxide solution calculated in accordance with Equation () to prepare a water glass with a modulus of 0.8–1.8. Aging time is 24 h. [ 35 ] Table 2 presents water glass chemical composition and mass fraction provided by the manufacturer. G=M1MxMxP×B×G1, where G is sodium hydroxide dosage, M1 is high modulus of water glass, Mx is the modulus after adjustment, B is Na 2 O content in high‐modulus water glass (%), G1 is the weight of high‐modulus water glass, P is Na 2 O concentration (%).…”

“…A similar explanation was observed by Ibrahim et al [5], who reported that the bulk density of fly ash geopolymer foam decreased from 1.65 g/cm 3 to 1.20 g/cm 3 with increasing PAS foam content. The bulk density of the fly ash-slag blended geopolymer foam achieved in this work was greater than in their work, which was due to the high-density slag addition [16]. The pore size distribution and total porosity of G-0, G-1 and G-2 are plotted in Figure 4.…”

“…The geopolymer foam also used the similar curing method as the unfoamed geopolymer. The constant formulations (sodium hydroxide concentration, solid:liquid, sodium silicate:sodium hydroxide and fly ash:slag ratios) were chosen as tabulated in Table 2, owing to the optimal ratios achieved in previous work [16].…”

“…Hui-Teng et al [62] determined the chemical composition of fly ash (FA) using the XRF technique. They found that the main compounds present in FA are SiO 2 and Al 2 O 3 with a total of 84.3% (w/w), while CaO is also current but only with a low amount of 3.89% (w/w).…”
