Porosity of Lightweight Fly Ash Agregates with Different Binders and Heat Treatments

In this study, coal fly ash was tested and the sintering process of this material was aimed at manufacturing sintered products for use as concrete aggregates. Addition of different binders such as bentonite and glass powder was attempted to improve the chemical and mechanical characteristics of sintered products. Influence of different sintering binders such as bentonite and glass powder and temperatures on the roperties of ceramic materials was reported. It is concluded that the porosity of fly ash changed with the binder types, content and different temperatures.
