A premix composition for producing an inorganic solid foamed mass by mixing component (A) an aqueous acidic phosphate solution of mainly polyvalent cations and phosphoric acid wherein between 0.8 and 1.75 protons of the phosphoric acid molecule of said phosphate are neutralized by the cations, which also contains one or more fillers dispersed therein, with (B) an oxide, hydroxide or polyvalent salt of a weak acid as hardener and a carbonate foaming agent. A process of producing an inorganic foamed mass using the premix composition and a solid foamed mass produced by the process are also disclosed. The process produces a relatively elastic cross-linked structure due to mainly the secondary phosphates being neutralized versus the tertiary phosphate groups.
