Abstract: This paper presents an experimental study of the effect of adding cellulose-recycled fibres
on mechanical and thermal properties of cement paste. Thermal conductivity, tensile strength
and compressive strength were investigated in terms of fibre content, fibre size and soaking-time.
The results reveal that the thermal conductivity decreases with fibre content in the
composite material and seems to stabilise around 10%. Up to a fibre content of 16%, the
compressive strength exceeds the standard for hollow non-load bearing concrete masonry.
Therefore it is possible to use for the construction of walls, ceilings and roofs of housing.
Backscattered electron (BSE) images taking in the scanning electron microscope (SEM)
shows that increasing Water-Cement ratio up a certain limit, which depends on fibre fraction,
improves the fibre dispersion and enhances mechanical strength.
