This study investigates the effect of dispersion of fiber in carbon fiber reinforced concrete
(CFRC) and coconut fiber reinforced concrete (CoFRC) by using sodium hydroxide (NaOH) as a dispersing
agent. The clustering and entanglement of the fiber in concrete decreases the uniformity of fiber which
reduces the strength of concrete A 0.5g/mL concentration of NaOH was used to enhance the dispersion of
fiber in concrete. The content of carbon fiber and coconut fiber was used 2% by volume of concrete and a
comparison is made between the effectiveness of NaOH on dispersion of both fibers. The effect of
dispersion was assessed by finding the mechanical properties of concrete. The concrete cylinders were cast
to find the compressive strength, splitting tensile strength and water absorption of concrete. The results
show that the compressive strength of CFRC with dispersed fiber is increased by 4.84% as compared to
untreated carbon fiber and compressive strength of CoFRC with dispersed coconut fiber is increased by
3.05%. The tensile splitting strength of CFRC with dispersed fiber increased by 9.76% and the tensile
splitting strength of CoFRC with dispersed fiber increased by 6.67% as compared to untreated fiber. The
use of dispersion agent increases the water absorption of concrete.
