Geopolymer cement (GPC) is made from aluminum and silicon, instead of calcium and silicon
(OPC).
Geopolymer are a type of inorganic polymer that can be formed at room temperature by
using industrial waste (waste materials) such as ground granulated blast-furnace slag (GGBFS),
Metakilon (MK) and Red mud (RD) or by products as source materials to form a solid binder
that looks like and performs a similar function to OPC.
Geopolymer concrete gets advantage
specification in resistivity to highly aggressive media and the resistivity to change in
mechanical and physical characterization at high temperature compared to the traditional
concrete.
this paper mainly study the preparation of Geopolymer cement to using in concrete
instead of Portland cement and discuss the effect different factors on the compressive strength
of Geopolymer paste without natural and chemicals additive (the effect ratio of (slag,
Metakilon, Red mud, sodium hydroxide and sodium silicate) Four parameters were studied.
The first parameter, the effect of changing ratio between sodium hydroxide and sodium silicate.
NaOH: Na2SiO3, secondly the effect of changing ratio between slag and Metakilon GGBFS
: MK, thirdly the effect of changing ratio between slag and Red mud GGBFS: RM, fourthly
the effect of changing degree curing temperature all samples curing different condition such
as air, water, steam, oven.
The results show that get high compressive strength at ratio
between sodium hydroxide and sodium silicate (NaOH: Na2SiO3), slag and Metakilon
(GGBFS: MK), slag and Red mud ( GGBFS: RM) is 1: 2.5, 0.95: 0.05, 0.90: 0.10 respectively
and the best mix have high compressive strength at various combinations between slag,
Metakilon and Red mud by ratio GGBFS: MK: RM is 0.85: 0.05: 0.10.
By inspecting the result
it can be noticed that in case geopolymer concrete the best curing method gives high
compressive strength in oven are compared air, steam, water and steam curing is better than air,
water and air curing is better than water curing and the effect temperature curing type on
compressive strength, Regardless of the compressive strength of samples increases with the
increase in curing temperature.
