The paper presented here is intended to make an investigation of the use of locally available materials in and around the Bellary district to make lightweight concrete (lwc). The district has harbored many steel and pig iron industries and brick casting yards which can provide raw materials for making lightweight concrete. The materials which are used in the present study are bloated slag (foamed slag), hard burnt brickbats, fly ash, ground granulated blast furnace slag (ggbs), and OPC Cement. Another abundantly, economically available material is Rice husk from local rice mills. This material, when used as an ingredient it helps to fulfill the engineering requirements of lightweight concrete. The fresh concrete proportions are fixed to give a slump of 25 – 50 mm. W/p ratio is used between 0.5 – 0.7 to achieve the required slump. The desirable engineering properties of lwc, such as unit weight and compressive strength, are arrived at by keeping some ingredients constant. And the rice husk is considered as one of the variables. In addition, modeling of the variables is made in order to know the relationships between important critical properties of lightweight concrete. It is possible to produce lightweight concrete economically as the ingredients, bloated slag, brickbats, and rice husk are abundantly available in the place of study. The study indicates the combination of materials such as fly ash, ggbs, bloated slag/brickbats, and rice husk yielded a lot, with densities varying from 1200 a 1400 kg/m3 and compressive strength varying in the range 7 to 11.21 N/mm2.
