Alkaline chemical activation of urban glass wastes to produce cementituous materials

Abstract

This is a preliminary work for evaluate the promising direction to reuse the recycled vitreous material by the alkaline activation than help to produce an alternative material with cementitious characteristic. NaOH and NaOH/Na2CO3 solutions were used like activation agents during the alkaline chemical activation of glass waste/blast furnace slag mixtures. The particle size of glass waste and nature of alkaline solution were analyzed to identify their influence on the mechanical properties. The NaOH/Na2CO3 solutions showed better performance to activate the blast furnace slag. The mechano-chemical process is an option for dissolve the glass waste in an alkaline solution. The alkaline solution formed with the glass waste will be use like alkaline activation agent for the blast furnace slag.
