In the literature many researchers have pointed out the
benefits of industrial waste for influencing the properties of
building materials, concrete and cement. Research carried out
by Lu et al.
shows that mixing of a certain amount of blast
furnace slag (BFS), fly ash (FA) fluxed with potash feldspar
and borax can be used to produce glass–ceramic glazes of low
density, low water absorption, perfect stain resistance, as well
as acid and alkali resistance.
