In this paper, the compressive strength of geopolymeric binder prepared
using the source materials such as fly ash, ground granulated blast furnace
slag (GGBS) and ceramic waste powder without using any conventional cement has
been investigated. The compressive strength was determined as per relevant
Indian Standard. The different parameters considered in this study are the
proportion of binder components such as ratio of Na2SiO3/NaOH solutions and
alkaline liquid to binder ratio. The various combinations of fly ash, GGBS and
ceramic waste powder considered are 80%, 10% &10%; 60%, 20% & 20% and
40%, 30% & 30% respectively. The ratio of binder to sand and Na2SiO3/NaOH
solutions is taken as 1:2 & 1:3 and 2 & 2.5. The alkaline liquid to
binder ratio is 0.45. The compressive strength of mortar cubes are determined
at 7 and 28 days. It can be concluded that, as the percentage of the Ceramic
waste powder increases, the compressive strength of the geopolymeric binder
decreases when compared to conventional binder. - See more at:
