Study on Preparation of Sintered Thermal Insulation Wall Material by High Addition Fly Ash

Abstract:

Article Preview

Production process of sintered thermal insulation wall material with high content fly ash was investigated in this paper. The proper addition amount of fly ash, the types and addition amount of the binders, the demand of molding and the molding process as well as the schedule of sintering was determined. The results show that: When the addition amount of fly ash is 65wt.%, the plasticity index of mixture mad is still more than 8. The compressive strength of the sintered sample can reach 12MPa; the porosity is in the range of 40-50%; Bulk density is 1.45g/cm3. If the macro porosity of the industrial product is designed as 40%, the final bulk density can reach 1.40g/cm3, and the theoretical thermal conductivity is less than 0.88w/(m2•K). This product can meSuperscript textet the demand of building energy saving and replace traditional external wall thermal insulation materials.
