Roller-Compacted Concrete (RCC) Performance
CONCRETE PERFORMANCE |
Features | Benefits |
High flexural strength
(500 to 1,000 psi) | Supports heavy, repetitive loads without failure and spans localized soft subgrade areas, which reduces maintenance costs and down time. |
High compressive strength (4,000 to 10,000 psi) | Withstands high concentrated loads and impacts from heavy industrial, military, and mining applications. |
High shear strength | Eliminates rutting and subsequent repairs. |
High density, low absorption | Provides excellent durability, even under freeze-thaw conditions; eliminates seepage through pavement. |
Low water content, low water/cement ratio | Increases strength, reduces permeability, and enhances durability and resistance to chemical attack. |
Aggregate interlock | Provides high shear resistance at joints and uncontrolled cracks to prevent vertical displacement or faulting. |
No steel reinforcing or dowels | Speeds and simplifies construction, reduces costs. |
No forms or finishing | Speeds construction, reduces cost, minimizes labor. |
No formed or sawed joints | Speeds construction, reduces cost. (To enhance appearance, joints can be sawn into RCC pavement.) |
Hard, durable, light-colored surface | Resists abrasion, eliminates need for surface course and reduces cost. The light color reduces lighting requirements for parking and storage areas. |
