Abstract

A concrete material, particularly for concrete compression elements transmitting compressive forces, to be used in a structural element as the thermal insulation in structural engineering, made of a high-strength concrete in the strength class C55 or higher, with the concrete being embodied as a thermally insulating, load-bearing material including titanium minerals as additives. Additionally, a structural element for thermal insulation and a brick-shaped thermally insulating element, each using said concrete material, are provided.

Claims

load-bearing material and includes titanium minerals as an additive.

2. The concrete material according to claim 1, wherein the titanium minerals acting as the additive for the high-strength concrete comprise ilmenite or titiferous iron ore.

3. The concrete material according to claim 1, wherein the titanium minerals acting as the additive for the high-strength concrete are present in a percentage of at least one of approximately one third of the concrete by volume or a weight portion amounting to approximately 50% or more.

4. The concrete material according to claim 1, wherein the high-strength concrete comprises a percentage of siliceous sand amounting to less than 10% by weight

6. The concrete material according to claim 1, wherein the titanium minerals acting as the additives for the high-strength concrete have a grain size of no more than 0.5 mm.

7. The concrete material according to claim 1, wherein fibers are mixed into the concrete.

8. The concrete material according to claim 7, wherein the fibers are steel fibers.

9. A concrete material according to claim 1, wherein the concrete includes at least cement as a binder.

10. A concrete material according to claim 1, wherein the concrete includes at least a reaction resin as a binder.
