The objective of this research work was to investigate the production of granulated foam glass-ceramic material from zeolitic rocks. The investigations have shown that grinding raw materials to particle size less than 0.5 mm and adding 13.8% of alkali content provide production of material with the following properties: particle density - 340 kg/m3, strength - 1.6 MPa and water adsorption - 13% at firing temperature of 850 °C. Expanded zeolite with alkali content is a material of glass-ceramic composition with amorphous part of 38.6% and crystalline part of 61.4% that gives higher strength in comparison with sponge glass.
