    Results obtained by numerous researchers concerning concrete strength anisotropy are analyzed. In some cases, the researchers have found that the compressive strength of specimens loaded at a right angle to a direction of concrete placing, f′c, is greater than for those loaded parallel to the above direction, f″c; in other cases, it is lower. This fact has been elucidated. In the cases where anisotropy is caused by the “internal” mix segregation, we come across f′c/f″c > 1; when the cause is in the “external” mix segregation, the result is f′c/f″c < 1. Given are recommendations for taking into account such anisotropy in core testing.
