Abstract
Geopolymer concrete consist of conventional concrete constituents replacing cement by
geopolymer materials. A geopolymer is a synthesized inorganic material that can be
used in a wide range of applications such as concrete. Geopolymer concrete can be
manufactured from wastes such as fly ash and granulated blast furnace slag.
Consequently, it does not result in the emission of carbon dioxide gas and requires law
energy during its manufacturing compared to that required during the production of
cement. Thus, it is considered as an environmentally - friendly material. Another
advantage of utilizing geopolymer concrete is the recycling of wastes production.
This work focuses on the produce geopolymer concrete using some types of locally
available industrial wastes alternative binder to the cement.
The used industrial wastes were ground granulated blast furnace slag, fly ash and
metakolin. The investigated materials were characterized using different analytical
methods and techniques (XRD,.~XRF, particle size distribution, and physical and
mechanical tests). Also, initial trials of different formulations were suggested to select
the most promising mix.
The present study was divided into two phase. The first phase determines the best
mixes that realize the highest compressive strength of geopolymer concrete, through
specifying optimal ratios of wastes (i.e., fly ash, metakaolin and granulated blast furnace
. slag) were used as binder materials, activators and ratios of mixing activators and
testing cubes at room temperature and after exposure to elevated temperature. The
second phase studying the behavior of structural reinforced slabs manufactured by
geopolymer concrete expose to elevated temperature.
Thirty mixtures were made using granulated blast furnace slag contents (350 - 400 -
450) Kg/m ’ ,six granulated blast furnace slag only control mixes with molarities
( 10 - 12) molar, four mixes ( 10 % - 20 % ) metakolin were replaced by (10 -12 )
molar and four mixes ( 10 % - 20 % ) fly ash were replaced by (l0 - 12) molar, after
that, cubes were made of geopolymer concrete from optimum mixtures from the results
of the first stage and carrying out the necessary tests on them at normal temperature and
after exposure to elevated temperatures then the reinforced slabs were made of
geopolymer concrete as weIl as the necessary tests w~re performed for the slabs at
normal temperature and after exposure to elevated temperatures.
