Specified strength of 100-80N/mm^2 high strength and highly fire resistant concrete was applied to a high-rise reinforced concrete building. Based on field experiment, mixture proportions of high strength concrete was determined. Variance of quality of fresh concrete and compressive strength of structural concrete was comfirmed to be controlled within allowable range. Properties of concrete before and after adding organic fiber for improving fire resistance showed nonsignificant level.
