What is black cement?
While rare, black concrete can be made by adding iron oxide, which is found naturally in magnetite—one of the most common iron ores. “When added to the concrete mix, the iron oxide particles encompass and coat the cement particles, which are 10 times smaller.” To make even darker concrete, carbon black can be used.
It's commonly used in driveways — and especially in gas stations — because it hides oil stains and grime. It's sometimes used in highways and runways because black absorbs heat and discourages ice. In decorative concrete, integral black with a silver release is a popular combination.

Blackening of the surface is common when the concrete is “burned by late and vigorous troweling”. The more the troweling effort, the more compacted and dense the concrete surface becomes. The result is a reduction in the moisture content (water cement ratio) at the surface.
As a ballpark estimate, the added cost of integral color for a six-bag mix (564 pounds of cement per cubic yard) should run about $50 to $70 per yard.

Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements ...
