Abstract

In this paper, effect of biomass addition on preparation of porous ceramite made by fly ash was studied. The results indicated that when the amount of biomass addition was increased from 15 % to 25 %, the porosity of ceramsite increased from 38,3 % to 46,7%, but excessive amount of biomass can affect other performances of ceramsite. Under this experimental conditions, the best experimental Scheme to preparation porous ceramsite is that the proportion of fly ash and clay is 5:5, calcination temperature 900 °C, mount of biomass addition 20 % and calcination time 40 min.

Keywords
