Geopolymer concrete (GC) is a sustainable construction material and a great
alternative to regular concrete. GC is a zero-cement material made from a combination of
aluminate, silicate and an activator to produce a binder-like substance.
This investigation focused on the effects of wet and dry cycles on the strength and
durability of fly ash-based recycled aggregate geopolymer concrete (RAGC). The wet-dry
cycles were performed approximately according to ASTM D559 standards.
RAGC specimens with nearly 70% recycled materials (recycled aggregate and fly
ash) achieved a compressive strength of approximately 3600 psi, after 7 days of heat curing
at 60ºC. Although the recycled aggregate is prone to high water absorption, the
compressive strength decreased by only 4% after exposure to 21 wet-dry cycles, compared
to control specimens that were not exposed to the same conditions. Accordingly, the RAGC
material developed in this study can be considered as a promising environmentally friendly
alternative to cement-based regular concrete. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection
