LABORATORY ANALYSIS OF RECYCLED AGGREGATES AND

recycled aggregates are technically viable to build granular pavement layers (sub-base and base) from low traffic flow, in spite of the variability of the CBR results to recycled aggregates and flakes PET mixtures. The NBR 15115/04 standard [10] provides the use of recycled concrete aggregates for base and sub-base of low-traffic volume roads.

Deformation Behavior of Recycled Concrete Aggregate during ...

Recycled concrete aggregate (RCA) is a relatively new construction material, whose applications can replace natural aggregates. To do so, extensive studies on its mechanical behavior and deformation characteristics are still necessary. RCA is currently used as a subbase material in the construction of roads, which are subject to high settlements due to traffic loading.

Use of selected waste materials in concrete mixes

Ground plastics and glass were used to replace up to 20% of fine aggregates in concrete mixes, while crushed concrete was used to replace up to 20% of coarse aggregates. To evaluate these replacements on the properties of the OPC mixes, a number of laboratory tests were carried out.
