Recovery and reuse of fly ashes (class F) waste for ceramic manufactures

摘要

In the present work we have studied the feasibility of Powder Metallurgy in order to obtain structural ceramics from resi-dual fly ashes powders. Charaderization of powders has been carried out followed with the manufacturion of a structural ceramic through poeder compacting and sintering. Some physical and mechanical properties as density, dimensional chan-ges and transverse rupture strength of the obtained materials were evaluated.
