In this experiment, we measure the concrete harden properties and the surface strain of the shell column after producing a shell column. The usability of HPC is still on observation due to the environmental difference. Because the thickness of the precasted shell column is 6-7 cm, and have to put the hoops into the shell column beforehand, therefore, to use HPC is to emphasize it’s workability and floatability. Because we can produce shell columns in the factory and wish to produce a certain quantity of production in a short time, therefore, stream curing is necessary . And the strength of the concrete has to reach 150 kg/cm2. According to the result of the research, application of HPC using on precast shell column could be very nice due to its workability and harden properties. Also, while poring concrete into shell columns, the maximum strain of the shell column surface is quite small and much safer than using mould and increasing the quality of construction.
