Abstract:
The traditional cement mortar
has limited characteristics. Because of the lack
of expected results, the engineering scope has
focused on alternative materials instead of
using the traditional constituents. As a result of
that different types of fibres have been used in
the past. In addition, the electrical distribution
cables no longer operate for power
transmission purposes when the length is not
adequate and after it reaches its’ end of life
and the disposal methods are not eco-friendly.
Therefore, the purpose of the study was to
evaluate the feasibility of cement mortar with
the metal fibre waste which was extracted from
electrical distribution cables. 1.35 mm
diameter aluminium fibres were used by
changing their volume ratio at four levels
0.5%, 1.0%, 1.5%, and 2.0%. Wet and dry
density and compressive tests were mainly
carried out to determine the behaviour of the
developed mortar systems. The wet, dry
densities and modulus of elasticity were
increased with the fibre addition. The
maximum compressive strength of the MFRM
was increased respect to reference mortar by
19.7% (3rd day), 19.8% (7th day), 11.7% (28th
day dry) and 25% (28th day wet). The overall
results of the study emphasized the mortar mix
with 1.5% of fibres performed well in all
mechanical tests and also it showed.
