Performance characteristics of recycled concrete aggregate ...

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 ...

PROPERTIES OF RECYCLED AGGREGATE CONCRETE

In terms of morphological characteristics, recycled aggregate is less favorable than natural aggregate. The grains are irregular, mostly with angular shape, rough and with cracked surface and porous. These grain characteristics grains significantly affect the workability of fresh concrete, as well as the permeability of liquids and gases in the hardened state; they also significantly depend on ...

Liquefaction characteristics of recycled concrete aggregates

01/05/2019  In this study, the dynamic behaviors (dynamic stress-strain behavior and liquefaction resistance) of recycled concrete aggregate (RCA) and quartz sand in an undrained condition were investigated through cyclic triaxial tests and compared. It was observed that RCA has a higher liquefaction resistance than quartz sand, which had a beneficial effect on the earthquake response.
