Abstract

Glass fiber reinforced concrete (GFRC) is a cementitious composite
reinforced by the addition of alkali-resistant glass fibers. GFRC is widely
used for various types of precast products in civil engineering industries.
GRFC mixes generally include silica sand to produce precast concrete elements;
however, silica sand was replaced with barite sand at the ratios of 5%, 10 %
and 15 % of wt. in order to reveal its applicability and potential for
different engineering purposes. The flexural strength and the
freeze-thaw(F&T) resistance of the composites were studied. The
experimental results showed that the replacement of silica sand with barite
sand up to 15 % of wt. enhances the mechanical properties of the composites in
respect to flexural strength and F&T resistance properties.
