Abstract :

The main objective of this research is to check the insulation properties of lightweight bricks; prepared by mixing some organic materials in the clay. Organic materials in bricks evaporate during burning, resulting small pores in bricks, causing reduction in weight and improve insulation of bricks. Six Different samples of bricks are made by replacing 5%, 10%&15% of clay proportion with Saw dust and Wheat husk, to make the bricks light and more insulated than normal brick. Brick samples are tested for absorption as well as direct compression test. Other important test performed is thermal test which is done in order to compare the rate of change of temperature of each sample and standard brick by providing suitable arrangement in the form of a mould having an electric heater of 1000W power and a digital thermometer having accuracy of 0.1 o C. Out of six specimens Wheat Husk 5% gave best results satisfying all the standards and having less weight and greater insulation than the normal brick.
