Abstract
Alkali activation of fly ash (FA) is a chemical
process which allows the transformation of the amorphous
structure which makes up most of its particles, in compact
cementitious skeletons geopolymers are called solid materials
usually consist of a alkali hydroxide and solid precursor high
content in silicon (Si) and aluminium. This paper presents the
effect of temperature and the curing time in the alkali activation
in FA pastes with 8M NaOH, geopolymers curing was carried out
at room temperature, 60 °C and 80 °C at aged 7 14 and 21 days.
Compression tests were conducted to obtain the strength of the
geopolymer and analysis by X-ray diffraction to determine the
new phases present resulting in higher compression resistance
with higher temperature and curing time, a change was detected
in the diffractogram because new phases present in the alkaline
activation product.
