Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by ...

Roller-compacted concrete pavement employs a concrete paving technology that involves laydown and compaction of a zero-slump concrete mixture ... The base course should provide sufficient support to permit full consolidation of the RCCP through its entire thickness upon compaction.

For studying the effect of roller compaction on three batches of IBN linear regression was done on straight line portions of the Heckel plot ().The parameters obtained from Heckel analysis of the three roller compacted batches, at 7.9 ± 0.4 kN force, are summarized in Table 3.Values of slopes derived from the Heckel plots decreased as we move from batch G1 to batch G3.

Roller-compacted concrete 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.

Roller Compacted Concrete "Roller Compacted Concrete (RCC) is a no-slump concrete placed with asphalt type paver and compacted by vibratory rollers." • Zero slump (consistency of dense, damp gravel) • No forms or finishing • No reinforcing steel ... •Supports heavy loads

ROLLER SUPPORTS Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface can be horizontal, vertical, or sloped at any angle. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. Roller supports are commonly located at one end of long bridges.

Roller Compacted Concrete Kemper Construction has a long and proven history of years of quality respectable work. This family owned company focuses on roller-compacted concrete, industrial paving, maintenance, site development and new project development.

This study discusses the properties of Phosphogypsum-based roller compacted concrete. The described demonstration project indicates that phosphogypsum-based RCC is suitable for the construction of parking facilities.

The development of Roller Compacted Concrete (RCC) caused a major shift in the construction practice of mass concrete dams and locks. The traditional method of placing, compacting, and consolidating mass concrete is at best a slow process. Improvements in earth-moving equipment made the construction of earth and rock-filled dams speedier and, therefore

Roller Compacted Concrete was first used for log handling facilities in Canada in the mid-1970's. This type of application requires pavement strength and durability to support the heavy loads. Surface appearance, texture, and smoothness are of lesser importance for these applications; therefore, coarser aggregates can be used.

Roller-Compacted Concrete Pavement . This Tech Brief presents an overview of the best ... to support the paver screed and rollers during placement and compaction operations. As a consequence, RCC pavements typically have been finished with rolling to achieve the specified density.

ROLLER-COMPACTED CONCRETE RCC consists of portland cement, coarse and fi ne aggregates, and water. RCC requires no forms, fi nishing, steel reinforcement or joint sawing. However, saw-cut joints can be easily created to offer an enhanced appearance and to help control cracking. The Process RCC takes its name from the method used to build it.

Roller Compacted Concrete...strong, dense and durable. Roller Compacted Concrete pavement is best described as a zero slump concrete that is placed with standard or high-density paving equipment and consolidated/compacted using steel-drum or rubber-tired rollers to .

The RCC Pavement Council is a volunteer industry trade association representing the interest of those involved with the construction of Roller Compacted Concrete Pavements. The RCC Pavement Council supports Research and Promotion to improve the quality of RCC pavements and expand their use in a responsible and sustainable manner.
