Recycled concrete aggregate is an excellent choice for concrete mixes, as it offers many benefits. These include environmental, structural and economic benefits. It can be used in a wide range of applications including concrete overlays, road base, and sub-bases. It is also more affordable than new concrete. During the recycling process, there may be several screening options.
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.
The mix's poor mechanical performance is one of the biggest drawbacks to recycled concrete. Recycled concrete has lower mechanical strength than virgin concrete. Additionally, it is more likely to crack and have uneven grades. Recycled aggregate can also impact the structure's durability. This is particularly true if recycled concrete is combined with fresh aggregate.
The lack of an appropriate source for recycled concrete is another problem. 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. Here are some common screening methods for reusing concrete.
A calcination process reduces the moisture content of the concrete. This can reduce the concrete's moisture content by up to six percent. This process also increases the powder's activity. This can be done in an electric rotary kiln. This is a popular way to make recycled concrete stronger.
Another issue with recycling concrete is the need to screen it for combustible impurities. It is also necessary to screen the concrete mix with a scalping screener. This is often used in conjunction to a deck screening machine. There are many materials that can be separated, depending on what equipment is used.
Another concern is the price of the material. While crushed concrete can be found locally, it's more expensive than the cost of mining new aggregate. Mobile crushers also make it easier to transport. Also, recycled concrete is a good option for disposing of construction or demolition waste. This helps preserve resources, reduce 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 identify and document the many uses of the product as well as identify any obstacles to its use. This information will be distributed to STAs and the FHWA Resource Center. This information will eventually be used for the development of a systematic deployment strategy.
The final report, which will be a summary and national perspective on the advantages of recycled concrete aggregate, will also contain the summary of the review. It will also provide technical guidance to STAs. It will also highlight other STAs' successes. It will contain a summary of the review's findings as well as interviews with STA staff.
