Abstract :

Cement mortar exhibits brittle behaviour due to its low tensile strength. The addition of fibers, either short or continuous, changes its brittle behaviour to ductile or quasi-ductile with significant improvement in tensile strength, tensile strain, toughness and energy absorption capacities. The binder in the fiber reinforced cement composites (FRCC) is mainly Portland cement. The recent environmental awareness in construction industry promotes the use of alternative binders to partially or fully replace the cement as its production creates environmental pollution due to release of CO2 into atmosphere. Recent years have seen a great development in new types of inorganic cementitious binders called “geopolymeric cement” around the world. This prompted its use in mortar and concrete, which improves the greenness of ordinary concrete. Efforts have been made to replace the current FRCC with “geopolymeric” binder resulting in fiber reinforced geopolymer composites (FRGC), which is greener than the former one. The development of FRGC is relatively new in the field of construction materials. This paper presents the development of FRGC for ferro-geopolymer and investigations on its properties with emphasis on compressive strength and tensile strength by heat and ambient curing. Based on the results obtained, the heat cured FRGC with 0.5% fiber was found to be have superior strength.
