摘要

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