Abstract
This study investigated the properties of cement mortar
reinforced with plantain pseudo-stem fibres and lime.
Experimental specimens with 0, 0.25, 0.5, 0.75 and 1% fibre
contents by weight of sand and 10% lime content by weight of
cement were prepared and tested on 7, 14, 21 and 28 days of
curing for density, tensile strength, compressive strength, SEM
and EDS. The 0.25% plantain pseudo-stem fibre reinforced
mortar achieved 23.4% compressive strength improvement over
unreinforced mortar specimens. There was between 6.89 and
13.80% increase in tensile strength of the plantain pseudo-stem
fibre reinforced mortar over the unreinforced mortar specimens.
A positive linear correlation was found between the compressive
strength and tensile strength of cement mortar reinforced with
plantain pseudo-stem fibres and lime with coefficient of
determinant (R
2
) values between 0.909 and 0.869. It was also
observed that the plantain pseudo-stem fibre reinforced lime
mortar specimen had some micro-cracks and voids from the
SEM analysis. Furthermore, The EDS analysis showed the
presence of calcium silicate hydrate with a Ca/Si ratio of
between 1.02 and 2.49, and Al/Si ratio of between 0.76 and 0.81
as the main oxide composition in the plantain pseudo-stem fibre
reinforced lime cement mortar. It therefore concluded that the
incorporation of plantain pseudo-stem fibre and lime positively
influenced the properties of the cement mortar with the 0.25%
fibre content being recommended for construction application.
