The objectives of this research in first year are to develop prefoamed optimal lightweight foamed concrete, using the polymer foam agent, with high lightness, flowability and strength for special use of structural application and to obtain its mechanical characteristics experimentally. This report presents extensive test data on the mix design, young's modulus, poisson's ratio, stress-strain curve, the characteristics of Strength of the foamed centre and also presents the mechanical characteristics according to foam sizes in the foamed concrete. From this research, lightweight foamed concrete which has better lightness, flowability and strength than the conventional prefoamed lightweight foamed concrete Is developed by mixing the admixtures such as silica-fume and fly-ash and the industrial by-product such as styrofoam for the purpose of practical use of Industrial waste. And field test, using deveolped foam concrete for the improvement of soft grounds was successfullv performed.
