Limited natural energy sources give impact on the selection of the material that can subtract energy consumption. Regarding to conservation energy, in the field of building and construction, the selection of concrete with good heat capacity is a requirement, besides light in weight. The objective of this study was to investigate the thermal conductivity of Foamed Concrete containing Rice Husk Ash (FCRHA). Rice husk ash (RHA) is the type fly ash that can absorb heat due to moisture. RHA The measurement of thermal conductivity on FC and FCRHA was conducted using box insulation and recorded using thermal data logger. The result showed that FCRHA absorb heat from the beginning when the heat is distributed, while FC slow absorp the heat. Modification FC by replacing sand partially with RHA provides an evolution to profitable use of construction materials in the heat absorption.
