A Fundamental Study on the Workability and Engineering Properties of Super High Strength Concrete Replaced Cement As Fly ash

Recently, owing to efficiency of the concrete work and the rationalization of construction structures, concrete is required to be super high strength. Furthermore, it is take a growing interest in execution and manufacture for super high strength concrete. This study is to investigate and analyze the influenced of flyash affecting on workability and engineering properties of super high strength concrete. In this experiment, the 28day's compressive strength of concrete using 15mm size of aggregate and flyash is over 800㎏/㎠ in the 20°/wt of water∼cement ratio. And the concrete using flyash have higher tensile strength than plain concrete.
