Influence of industrially produced recycled aggregates on ...

This research aims at evaluating the main risks for the durability of concrete made of industrially produced recycled aggregates called Recycled Aggregate Concrete (RAC). A characterisation of recycled aggregates is performed and their peculiarities are highlighted. A comparison between the behaviour of RAC and that of ordinary natural aggregate concrete is carried out. The influence of both ...

Reuse of Clay Brick Waste in Mortar and Concrete

The application of recycled clay brick can not only solve the disposal problem of demolished solid waste but also reduce ecological environment damage caused by the excessive development of resources. Clay brick powder (CBP) exhibits pozzolanic activity and can be used as cement replacement. Recycled clay brick aggregate (RBA) can be used to substitute natural coarse aggregate.

Crushed Returned Concrete as Aggregates for New Concrete

Recycled concrete aggregates (RCA) have higher water absorption rates than virgin aggregates. Higher absorption rates are indicative of higher volume fractions of old cement mortar adhering to the virgin aggregate particles in the original concrete1-3.

Recycled Concrete: The Pros and Cons - Braen Stone

Recycled Concrete Aggregate At-A-Glance. When a concrete sidewalk, road, parking lot, or structure needs to be excavated and replaced, the concrete is often discarded into a landfill. Because chunks of concrete are not biodegradable and are unable to decompose over time, the waste takes up a great deal of space and creates environmental concerns.

Today, the use of recycled aggregates as a substitute for a part of the natural aggregates in concrete production is increasing. This approach is essential because the resources for natural aggregates are decreasing in the world. In the present study, the effects of recycled concrete aggregates as a partial replacement for fine (by 50%) and coarse aggregates (by 100%) were examined in the self ...
