【Abstract】 This paper introduces a new type of blowing agent in the procedure of air entraining brick production which can be substituted for alumium-based blowing agent, Experiments show it is feasible that calcium carbide can be used as non-alumium-based blowing agent to produce air entrainment brick instead of alumium-based blowing agent. This method not only reduces production costs,but also eases up the intense situation of aluminium market which has a comparatively economic benefit.更多还原
