| Summary: | Currently there are several kinds of building wall thermal insulation materials commercially available in
Malaysia, however the issue with all these materials is that they are not eco-friendly. This paper attempts
to reduce the dependence on non-eco-friendly insulation material by developing thermally efficient ecofriendly
bricks. The prototype brick developed by incorporating locally available sustainable waste material
was subjected to initial investigation on physical, mechanical, thermal and microscopic studies. The
investigations revealed that the thermally efficient prototype mix design using glass powder and palm oil
fly ash along with lime as binder is able to provide strength to the bricks. Also, usage of oil palm fibres
were beneficial in lowering the thermal conductivity of bricks. At incorporation of 1% wt of OPF, compressive
strength was found out to be 7.21 MPa and thermal conductivity was 0.39 W/mK, which indicates
the proposed bricks can be an alternative to non-eco-friendly commercial common bricks. The advantage
of the proposed bricks is two-fold: having low thermal conductivity will make it an energy efficient
option, second is the usage of sustainable resources makes it an eco-friendly product. |
