Vitreous Foam with Thermal Insulating Property Produced with the Addition of Waste Glass Powder and Rice Husk Ash

Closed pore glass foams with dimensions of 60mm × 20 mm were produced using agro-industrial residues. Samples containing sodo-calcic powder (78%wt) and rice husk ash (16%wt) characterized, their technological properties investigated. The samples synthesized in a conventional muffle furnace at 750–800–850 °C. results presented for apparent density (0.24–0.29 g/cm3), compressive strength (1.5–2.3 MPa) thermal conductivity (0.021–0.025 W/mK) meet the standards commercial foam glasses. Low viscosity was achieved all temperatures as result addition to cell structure. X-ray fluorescence showed that silico-sodo-calcic type (SiO2, Na2O CaO), rich SiO2 (as well CaO, Na2O, Al2O3, K2O Fe2O3). mechanical low conduction material good efficiency use civil construction insulating material. Material made this way has lower production cost, additionally transforms waste into co-products, generating added value, favoring consecutive circulation, clean circular economy.
