Abstract:Magnesium slag and waste glass were applied as raw materials to produce foam glass. The effects of dosages of foaming agent (Na2CO3), foam stabilizer ((NaPO3)6) and flux (Na2B4O7?10H2O) on properties of foamed glass were investigated by orthogonal experiment. The density, water absorption, mechanical properties, and phase analysis of foamed glass with different foaming agent dosages were detected and analyzed. The results show that magnesium slag foamed glass contains CaSiO3 crystal phase structure, and foaming agent is the most significant factor. Foam glass has the optimum properties with apparent density of 598 kg/m3, compressive strength of 5.34 MPa, and absorption rate of 0.43% under the conditions including dosage of foaming agent, foam stabilizing agent and flux of 2%, 3%, and 2% respectively.
