Roller Compacted Concrete Mix Design

Today rcc is used for any type of industrial or heavy duty pavement.

Roller compacted concrete mix design.

These qualities have taken roller compacted concrete from specialized applications to mainstream pavement. It includes detailed overviews of rcc properties and materials mix ture proportioning structural design issues and production. For technical assistance regarding roller compacted concrete contact the portland cement association or the national cp tech center. The reason is simple.

Mix design proportioning methods for roller compacted concrete rcc. Selection of proper materials and correct proportioning is critical to the production of quality roller compacted concrete mixtures. Roller compacted concrete mix proportioning method i of making roller compacted concrete. Roller compacted concrete strong dense and durable.

Based on beams and cores obtained from a test section the relationship between the compressive and flexural strengths of roller compacted concrete appears to be similar to that for conventional. As a result the flexural strength of roller compacted concrete depending on the mix design is generally high ranging from 500 to 1 000 psi. Different mixes of roller compacted concrete can be designed to meet the different requirements of the two applications. Sln 1ctural design issues ruld production and.

Mix design proportioning methods for no slump concrete applicable for roller compacted concrete. Uses the principles of soil compaction to produce a lean rcc where the optimum water content of the concrete is the one that produces the maximum dry density of the mixture. The mixture of roller compacted concrete need to be dry enough to avoid sinking of the vibratory roller equipment but wet enough to allow sufficient distribution of. 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 achieve a durable wear resistant surface.

Roller compacted concrete pavement is a type of non reinforced concrete pavement placed with high density paving equipment and then compacted with vibratory rollers. The mix design of rcc usually consist of a high amount of stone portland cement with a replacement of fly ash a minimal amount of sand and of course water to hydrate the mix. Materials used in rcc mix design a cementitious materials. Cement content is generally low typically 70 to 130 kg m3.

Any kind of. Roller compacted concrete pavements and design construction and testing of rcc.
