Lightweight geopolymer-based hybrid materials

The present study reports on the preparation and characterization of new organic-inorganic geopolymer based hybrid foams obtained by reacting an aluminosilicate source and an alkalisilicate solution with mixtures of dialkylsiloxane oligomers or organic resins precursors. By using different amounts of Si0 powder as in situ foaming agent, hybrid geopolymer-based foams with densities ranging from 0.25 to 0.85 g/cm3 were successfully prepared. These...
