This paper review the utilization of Industrial Boiler Ash (IBA) replacing sand has been introduced in aerated concrete for common use in building construction. The Industrial Boiler Ash from Tanjung Bin Power Plant, Malaysia was used in this study. It is believed beneficial as by adding this precious material, it may improve properties of aerated concrete mechanically and thermally especially in the effect on improving the thermal conductivity. This paper presents the effects of using different character of mixing constituent such as various amount of foaming agent and range of superplasticizer content on the compressive strength. Besides that determination on the final product properties in microstructure were also investigates. The results show that using the IBA have a lower density compared to normal sand with a dry density of 1.408kg/m3 which a compressive strength of 5.258 MPa but also observed beneficial as it might improve the thermal conductivity behavior with 0.52 W/mK compared to normal mortar concrete having 2.52 W/mK. This indicate that the use of Industrial Boiler Ash aerated concrete give a less impact of heat due to low thermal conductivity created.References
