Recycled Aggregates
Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests required of conventional aggregates. Recycled concrete aggregates contain not only the original aggregates, but also hydrated cement paste. This paste reduces the specific gravity and increases the porosity compared to

Recycled Aggregate Concrete: Particle Packing Method (PPM) of Mix
In this work, Recycled Coarse Aggregate (RCA) is replaced 100% to produce RAC. The Particle Packing Method (PPM) is proposed for the mix proportioning of concrete. In PPM, the smaller particles are selected to fill up the voids between large particles and so on.

Effects of Recycled Aggregate on Concrete Mix and Exposure to Chloride
Concrete mix with 30% recycled aggregate had the lowest chloride penetration after 2 weeks of saturation and performed better than a concrete mix with 100% natural aggregate. Owing to the lower density and higher water absorption of recycled aggregates, chloride ion diffusion increased with increasing recycled aggregate content beyond 2 weeks.

As the concrete commonly comes from demolished building sites, it may also contain some trace elements of glass and other building materials. Recycled concrete aggregate is not suitable for making concrete, and is not as clean as blue metal is for drainage, but is a cost effective alternative to the blue metal used by many plumbers for backfill and drainage projects.
