Concrete mixes can be made with recycled concrete aggregate. It offers many advantages. These include environmental, structural and economic benefits. It can be used for many purposes, including as road base or sub base and concrete overlays. It is also cheaper than buying new concrete. Several screening processes can be used during the process of recycling.
Recycling concrete aggregate has seen an increase in popularity over the past few years. This technology offers many advantages, including lower environmental impact, lower costs, as well as an environmentally friendly method to dispose of nonbiodegradable trash. But, you should also consider the potential drawbacks to using recycled concrete.
Recycled concrete has a lower mechanical performance, which is one of its main disadvantages. Concrete made from recycled concrete is less sturdy than concrete that has been poured directly. It can also crack easily and be unevenly graded. Also, a high amount of recycled aggregate could affect the durability and strength of a structure. This is especially true for recycled concrete that is mixed with new aggregate.
Another problem with recycled concrete is the inability to find a suitable source of aggregate. Although the construction industry has started to recycle concrete that is broken, there is still a shortage in natural aggregates. It is important that the mix is thoroughly refined before it is used in construction. These are some of the most common screening methods to refine recycled concrete.
The concrete's moisture content will be decreased by the calcination process. This process can lower the moisture content to less than six percent. It also increases the activity of the powder. This can be done in an electric rotary kiln. This is a common way to make recycled concrete more durable.
Recycling concrete also requires that the aggregate be screened for combustible contaminants. Also, a scalping filter is required to screen the concrete mix. This process is usually used in conjunction with another screening method, such as a deck screener. Depending on the type of equipment, a variety of materials may be separated.
Another concern is the cost of the material. Although crushed concrete is readily available locally, it is much more expensive than mining new aggregate. Additionally, portable crushers reduce transport costs. Also, recycled concrete is a good option for disposing of construction or demolition waste. It can help preserve resources, cut freight costs, and eliminate tipping fees.
The United States Department of Transportation conducted an extensive study of the American use of recycled concreteaggregate. The project will document the various applications, identify the benefits of the product, and identify barriers to its use. This information will be distributed to STAs and the FHWA Resource Center. It will eventually be used to create a systemic deployment plan.
The final report will include a national perspective and a summary of the study. The final report will provide technical guidance for STAs. It will also highlight other STAs' successes. It will include a summary of the review's findings and interviews with STA staff.
