Performance in Thermal Conductivity of Bricks Containing Palm Oil Fuel Ash and Expanded Polystyrene Beads

Sustainable development has encouraged us to sustain the balance between the development of the country and the biodiversity conservation. Productions of lightweight bricks with thermal conductivity and density that have acceptable compressive strength are accomplished. Palm oil fuel ash (POFA) was...

Description
Summary:Sustainable development has encouraged us to sustain the balance between the development of the country and the biodiversity conservation. Productions of lightweight bricks with thermal conductivity and density that have acceptable compressive strength are accomplished. Palm oil fuel ash (POFA) was used as partial cement replacement and an expanded polystyrene (EPS) beads was used as sand replacement to manufacture of bricks. In this study, the control sample with a Cement: POFA: Sand: EPS ratio of 1.0: 0: 3.0: 0 were produce. The cement in the sample is replace by 25% of POFA and 0%, 20%, 30%, 40%, 50% of EPS. In this study, the test conducted was a thermal conductivity test and density test of the POFA, EPS beads and brick raw material. This sample was cured under full air-dry curing conditions were applied in this experiment. The density of bricks containing 0% of EPS Beads with 25% of POFA are higher than that of brick containing 50% of EPS Beads with 25% of POFA which are 1850 kg/m3 and 1357.14 kg/m3, respectively. The higher the percentage of EPS beads, the lower the brick's density. The thermal conductivity of bricks containing 0%, 20%, 30%, 40% and 50% EPS with 25% POFA show that brick containing 50% EPS with 25% POFA have a lower thermal conductivity with 0.09 W/m°C due to the density of the sample.
