  • The Use of Fly-Ash and Bottom Ash, in Geopolymer Mortar

    Bottom ash (BA) is a waste material generated from coal-fired thermal power plants. Bottom ash being in contrast to fly ash, usually has much lower pozzolanic property which makes it unsuitable to be used as a cement replacement material in concrete. However, as its particle distribution is similar to that of sand which makes it attractive to be used as a sand replacement material. Also according to Andrade et. al., bottom ash plays an efficient filling role to fill up voids in the concrete specimens. It is therefore a suitable material to be used as fine aggregates for the replacement of natural sand.
