Roller Compacted Concrete
Roller Compacted Concrete (RCC) is an extremely tough, zero or low slump concrete with compressive strengths greater than 4,000 psi. RCC combines strength, durability, and economic high capacity production.
RCC is commonly used for:
- Hardfill in dam construction
- Intermodal facilities
- Paving roads and shoulders
RCC takes its name from the process used to make it.
Mixing: BHS’s pugmill’s have been used around the globe to mix RCC. The aggressive mixing action disperses the low amounts water into the stiff dry mix along with cement, fly ash and other admixtures.
Controls: Thompson Rock Mixers’ proprietary control system accurately doses all ingredients according to the recipe. Our computer engineers are based in the USA for trouble shooting and support.
Transport: Dump Trucks transport the RCC mix from the plant to laydown crew.
Placement: The mix is placed in lifts of 4-9 inches in thickness.
Compaction: Steel drum vibratory rollers compact the mixture to the required density.
