Inorganic foams were prepared from alkali activated fly ash and aluminum powder blowing agent. Curing process was accelerated by thermal treatment at 80 °C for 12 hours. Bulk densities ranged between 420 and 800 kg/m3, depending on batch proportions. Compressive strength was found in the range 3.7-9.0 MPa, Young's modulus 0.6-1.1 GPa, thermal conductivity 0.14-0.16 W/m/K. Young’s modulus was reproduced using 2D numerical simulations and analytical homogenizations.
