01/03/1999 · Because fly ash from cellulose industries contains considerable amounts of free lime and sulfate, they are potential secondary raw materials for the production of autoclaved aerated concrete. Laboratory experiments were performed by replacing lime and sulfate in conventional autoclaved aerated concrete mixtures by fly ash. Compared to a reference series, samples with even higher compressive ...
In the present work, mixtures of mill scale (MS), an industrial byproduct derived from the flaky surface of hot rolled steel, and lignite power station fly ash (FA), both originating from Greek industries, are examined as the starting materials for the sustainable development of ceramics employing powder metallurgy (P/M) fabriion procedures. It should be emphasized that the safe ...
