The thin wall of a pre-stressed concrete LNG storage tank is very intricate with many reinforcing bars, sheaths and other steels, and it is very difficult to fill it up with concrete. So, for the construction of the wall of the structure, it is compeled to apply the inverse casting method by using high performance concrete, which has high strength, high endurance, high workability and non shrinkage. This report desrcibes the results of the experimental study on a high performance concrete and its practical use to actual structure, in order to find the details as followings: (1)The limit of the unit coarse aggregates upon filling capacity of concrete. (2)The effect of low heat type cement upon controlling thermal stress. (3)The effect of expansive admixture and aluminium powder upon volume stability.
