It includes detailed overviews of rcc properties and materials mix ture proportioning structural design issues and production.
Roller compacted concrete mix design.
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.
Today rcc is used for any type of industrial or heavy duty pavement.
Roller compacted concrete strong dense and durable.
Mix design proportioning methods for no slump concrete applicable for roller compacted concrete.
Roller compacted concrete mix proportioning method i of making roller compacted concrete.
Roller compacted concrete pavement is a type of non reinforced concrete pavement placed with high density paving equipment and then compacted with vibratory rollers.
Cement content is generally low typically 70 to 130 kg m3.
Different mixes of roller compacted concrete can be designed to meet the different requirements of the two applications.
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.
For technical assistance regarding roller compacted concrete contact the portland cement association or the national cp tech center.
Selection of proper materials and correct proportioning is critical to the production of quality roller compacted concrete mixtures.
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 reason is simple.
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.
Any kind of.
Tough fast economical.
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.

It is therefore recommended that users determine how soon the pavement needs to be opened for traffic and then design the most cost effective pavement section and roller compacted concrete mixture meeting the requirement.
These qualities have taken roller compacted concrete from specialized applications to mainstream pavement.
While the finished product is essentially concrete pavement the engineering and construction of this pavement is very different from conventional concrete pavement.
