Types of concrete - Wikipedia

The concrete mix achieves a high density and cures over time into a strong monolithic block. Roller-compacted concrete is typically used for concrete pavement, but has also been used to build concrete dams, as the low cement content causes less heat to be generated while curing than typical for conventionally placed massive concrete pours.

For this purpose, concrete must have high strength and high density. Heavyweight and high strength concrete can be used for shielding purposes if it meets the strength and radiation shielding properties.

High Strength, High Density Concrete

Most high density concrete for shielding has been made with naturally occurring iron ores, titanferous iron ores, hydrous iron ores, and barite. Although structural strength is an important factor in high density concrete, workability and density have been the major factors previously studied.

High Density Polyurethane Concrete ... - Polyjacking.com

High-density polyurethane concrete leveling is the most efficient, cost-effective, and environmentally-friendly way to raise and stabilize existing concrete slabs. Used extensively by DOTs for over 3 decades, polyurethane concrete leveling has been real-world tested under the toughest conditions.
