10mm Recycled Concrete is a standard Aggregate used in civil construction, commercial developments, and residential applications. These include drainage, pipe bedding, backfilling retaining walls, trenches, roads and pathways, rubble pits, and other applications requiring extensive drainage in areas with heavy water flow.
Recycled concrete aggregates are being considered for use in the O'Hare Modernization Project (OMP). Laboratory testing using a two-stage mixing method showed that using RCA from Chicago O'Hare International Airport for the coarse aggregate reduces bleeding and segregation and produces similar workability, compressive strength, and ...

Steel slags, slacker aggregate, recycled concrete, and rubblized concrete pavement have been identified as sources of tufa precipitate, which builds up in pipe underdrains and …
There are two schools of thought. One is yes use filter rock to bed the pipe for ease of grading and to prevent build up of water under the pipe. The other is to use impervious soil material because the water at the inlet may flow under the pipe instead of through it. It depends on the situation and the engineer.
For around 70 years, research has showed that using recycled aggregates (RAs) from CDW to replace natural aggregates (NAs) in new concrete application as …
Crushed concrete is recycled concrete that comes in graded and screened sizes for use as a hard fill or drainage aggregate. Versatile Atlas Concrete can supply a range of products to suit any application, for a …

Concrete pavement recycling is an environmentally sustainable choice in terms of energy and other life- cycle impacts. It can reduce the mining, use, and transportation of …
In 12" and 15" diameter sizes, SDR35 pipe is 25-45% more costly than class III or IV concrete pipe. In 18 and 21" diameter sizes, SDR35 pipe is similar to or up to 15% more than concrete pipe. 24" and 27" sizes in SDR35 pipe are 10-30% more costly than concrete pipe. CAUTION. Beware of chipping, breaking, or faulty joints when handling.
This research was undertaken to investigate the suitability of recycled construction and demolition materials as alternative pipe backfilling materials for stormwater and sewer pipes. Three commonly found recycled construction and demolition waste materials, (crushed brick, recycled concrete aggregate and reclaimed asphalt …
A green concrete mix containing 60 per cent RCA is being offered by one manufacturer for the DIY market, while another company is even branding recycled concrete aggregate. Conclusion Recycled concrete aggregate is a readily available, flexible, and sustainable product that has a proven track record as a high-performance …
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon …
Controlled Density Fill (Also known as lean concrete) This fills the trench without a need for a secondary compaction operation.This is suitable for particularly narrow areas that cannot handle a large piece of machinery for compaction, or in areas that are heavily trafficked and need to be completed sooner.
RECYCLED CONCRETE USES. Old, unneeded concrete can be recycled and used to create recycled aggregate. In most cases, recycled aggregate will be used as a subbase material, but it can also be paired with materials and reused as an aggregate in new concrete. CA6 recycled PCC and Grade 8 recycled are common aggregates made …
I believe the recommendation is to surround all buried pipes with pea shingle or similar aggregate to avoid puncturing or crushing them when compacting, …

For the more rigid commonly used pipes such as Ductile Iron and Concrete Pipe etc, caution should still be taken during installation, but the pipe can typically withstand more pressure above. Also caution must be used when backfilling and compacting pipe trenches to assure the trench walls do not cave in.

Another method for recycling concrete is pulverization. Pulverizing the concrete isn't the best way to recycle concrete, however. It can make the separation of contaminants much more difficult, lowering the quality of the finished RCA. Repurposing Recycled Concrete Aggregate. When concrete is recycled, it can be broken down …
