Recycled Aggregates

Use of recycled concrete aggregates (RCA) as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA, such as elastic and plastic deformations of RCA is therefore, needed to assess RCA's application as an unbound pavement material. In this study, repeated load tri-axial (RLT) tests were ... · Also, the use of recycled concrete aggregates can be very effective for use as a weak or filling concrete and would be of benefit in areas with very little natural aggregate available to the consumer without large transport costs (9) 2.7 Characteristics of 2.7.1 · A recent survey conducted in shows that recycled concrete aggregate (RCA) is the most commonly used material among the Department of Transportation Agencies in the USA (Edil et al. ). Carbonation is one of the ongoing degradation processes acting on cement paste and concrete.
