What is Roller Compacted Concrete?
Just as the name indicates roller compacted concrete uses modified asphalt rollers to consolidate a concrete mixture; similar to that of regular concrete into a durable surface. The American Cement Manufacturers describes the similarities of RCC to conventional concrete by explaining it “…has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone. But unlike conventional concrete, it’s a drier mix—stiff enough to be compacted by vibratory rollers.” This variation of concrete often has compressible strengths greater than 4,000 psi.
How is Roller Compacted Concrete different?
Roller Compacted Concrete (RCC) contains a very similar mixture of concrete water and other aggregates to that of regular concrete. The difference is that RCC is much drier and has practically zero “slump” (Slump describes how consistent a concrete sample is) making it much more consentient. When done it looks and feels more like damp gravel than wet concrete meaning the down time between application and full usage is much less. While asphalt and convention concrete have several benefits in any industrial situation where heavy equipment is being used RCC is the obvious answer for a low cost, long term low maintenance surface.
Compare the Difference Below
- Can be damaged by vehicle chemical leaks
- Requires maintenance over the lifetime of surface.
- Best used on high traffic areas of high speeds such as high ways.
- Susceptible to subgrade failures due to over use which lead to cracks, ruts, and pot holes.
- Has a greater impact on the immediate environment than lighter colored alternatives.
- Lower maintenance than asphalt
- Because of its smoother surface it is better suited for higher speed traffic
- Requires longer down time after application for concrete to dry.
- Most labor intensive due to forms that must be built and set in place before concrete can be poured.
- Less susceptible to ruts, pot holes and cracks than asphalt.
ROLLER COMPACTED CONCRETE
- Best suited for low-speed, industrial or military applications such as metal yards, distribution centers, or other areas of heavy equipment use.
- Low initial cost
- Low maintenance
- Surface appearance and smoothness are a secondary priority
- Less down time after application. RCC can be walked on immediately after application and traffic in as little as 4 hours.
