A General Assessment of Fiber-Reinforced Geopolymer Concrete against Freeze-Thaw Cycles

The strength and durability of concrete against freeze-thaw effects is essential in determining the service life of concrete used in cold climates. One of the effective ways to reduce the microstructure damage caused by the freeze-thaw impact on concrete is to add different fibers to concrete mixes. The fibers added into the concrete effectively limit the micro and macro cracks formed after the freeze-thaw cycles in the concrete microstructure, increasing the durability of the concrete significantly. Geopolymer concretes environmentally friendly new generation concretes developed as an alternative to conventional concretes to reduce the carbon dioxide (CO2) gas emission during cement production. Geopolymer concretes have a semi-brittle structure like conventional concretes, and micro and macro-cracks occur in their microstructures, especially under tensile stresses. To improve the strength and durability properties of Geopolymer concretes against these cracks, different types of steel and synthetic fibers are used in the mixtures. This study examines the strength and durability behavior of different kinds of fiber-reinforced geopolymer concrete after freeze-thaw cycles.
