摘要：Styrofoam or expanded polystyrene or Thermocol is used as packing material in food andmanufacturing production equipments to absorb vibration during handling and transportation process. After thisprocess, the Styrofoam which is used to protect the equipment normally is disposed as a waste. It is estimated that itproduces large amount of wastes as it is abundantly used in the market. An attempt is made to modify the wasteStyrofoam pieces as light weight aggregate. Due to its light weight characteristics, it has potential to serve asaggregates to replace coarse aggregates. Concrete is the most versatile material due to its continuous demand. Manyresearchers and scientists have developed number of techniques to improve the parameters of concretei.e.strength&durability. Engineers are continuously pursuing to improve the performance with the help ofsupplementary cementitious material like blast furnace slag, Flyash,steel slag, silica fume etc.The main objective of thisinvestigation is to study the properties such as compressive strength,in plane shear strength,tensile strengths oflightweight concrete containing Styrofoam. Nano materials such as Iron oxides are also used in this investigation.Inthis investigation 89% of binding material such as cement which is constant is used. The remaining 11% is replacedwith silica fume, slag and GGBS with equal proportions. In addition Nano Fe2O3is used in the percentages of0.5,1.0,1.5 with respect to 11%. This has resulted the increase in strengths up to 1% addition of Fe2O3 and afterwardsthey get decreases.
