The purpose of this paper is to clarify effect of sampling depth for distribution of compressive strength and strength development of core specimens in full scale model of high-strength concrete column using various cements. As a result, the following conclusions are obtained: 1) Compressive strength ratio difference between uppermost and lowermost part of core specimens is reduced in proportion to core strength. 2) Coefficient of variation of core strength is reduced in proportion to core strength. 3) Apparent density ratio difference between uppermost and lowermost part of core specimens is reduced in proportion to core strength.
