Porous alumino-siliceous (PAS) materials are attractive for use in a wide variety of construction and adsorption materials. In the present study, the porous alumino-siliceous materials were synthesized by a geopolymerization method in a reaction from ceramic waste, metakaolin, and an alkaline solution, H2O2 (as a foaming agent) and either pork lard or butter (surfactants). Different amounts of the surfactants (2.5-15 wt%) were added to the samples. The pore shape in the PAS materials was affected by the type of surfactant used. PAS materials with small open pores and high porosity were successfully fabricated with butter as a surfactant. The compressive strength value trend was related to total porosity. The relationship between compressive strength and porosity was found to be consistent with a model proposed by Ryshkewitch. The results suggest that this material can be used as a foam material.
