Geopolymer is one of alternatives to
choose as a construction material. Hence, the
use of geopolymer in order to replace the
cement is to reduce the CO2 emissions from
the cement industries. Geopolymerization
reaction can be applied to utilize solid wastes
and by-products containing silica (SiO2) and/
or alumina (Al2O3) which are called pozzolanic
materials or pozzolans. Pozzolans from
industrial and agricultural wastes such as
fly ash, bagasse ash and rice husk ash were
handled to produce geopolymers in previous
research (Tippayasam et.al., 2010).
