A concrete tower is provided. The concrete tower may be a concrete tower for a wind turbine. The compressive strength of the concrete is changed in dependency of the height of the tower. The concrete tower includes a number of tendons that are arranged to pre-stress the concrete tower. Each tendon is anchored with the concrete tower at a first end of the tendon and at a second end of the tendon.

1. A concrete tower for a wind turbine, comprising: a plurality of tendons,wherein the plurality of tendons are arranged to pre-stress the concrete tower, and wherein the compressive strength of the concrete is changed in dependency of a height of the concrete tower, andwherein a density of the concrete increases proportionally to an increase of the height of the tower. 2. The concrete tower according to claim 1, wherein each tendon is anchored with the concrete tower only at a first end of the tendon and at a second end of the tendon. 3. The concrete tower according to claim 2, wherein the second end of each tendon is anchored near a top of the tower, and/orwherein the first end of each tendon is anchored near a foundation of the tower. 4. The concrete tower according to claim 1, wherein the concrete includes a first compressive strength at the foundation of the tower,wherein the concrete includes a second compressive strength at the top of the tower, andwherein the second compressive strength is greater than the first compressive strength. 5. The concrete tower according to claim 1, wherein at least two segments are arranged to construct the concrete tower,wherein the at least two segments are pre-stressed by the plurality of tendons,wherein each tendon is anchored with the resulting tower only at a first end of the tendon and at a second end of the tendon,wherein the first end of each tendon is anchored with a first segment, which is arranged near or at the foundation, andwherein the second end of each tendon is anchored with a second segment, which is arranged near or at the top of the tower. 6. The concrete tower according to claim 1, wherein the compressive strength of the concrete increases proportionally to an increase in the height of the concrete tower. 7. The concrete tower according to claim 1, wherein a cross sectional area of the concrete decreases when the height of the concrete tower increases.
