» Posted by on Jan 17, 2018 in Demolished Concrete | 0 comments

When building a new property on an existing building, the old should be removed. Demolishing a building is important so a new one can rise. Building demolition is never a DIY task, it’s a laborious task. Should you need a demolition company, you can call Myrtle Beach Demolition Services for your demolition needs.  

Demolished Concrete 

Once the project is done, you will be left with piles of concrete. You wouldn’t want to just throw them away and add up to the waste of our land, so better recycle them and reuse them. Recycling and reusing concrete will reduce the costs of your construction, and at the same time you’re going to give the environment a favor. Follow the recycling tips below.  

Using Old Concrete 

When demolishing a building, make sure to tell the demolishing company that you’re reusing the old concrete. Reclaimed concrete can be used on the walkways; you can also use the concrete to provide gaps for rainwater to reach the soil. Once the old concrete is crushed and processed, you can turn it into an aggregate.  

The demolished concrete pavement can also be used as a base for the asphalt pavement. It will undergo the process of rubblization. It can also be used as a bed foundation for the utilities underground. If you plan on using the recycled concrete on the new concrete, you can do so by combining it with a virgin aggregate. Other uses of recycled concrete are for making pots, blocks and benches which are beneficial for community use.  

Benefits of Recycling the Concrete 

Like we mentioned, recycling the old concrete will help you reduce your construction costs. It also extends the life of landfills for many years more. You can earn points for certification from the LEED Green Building Rating System. The reused concrete also saves transportation costs because you can recycle them on site, reduces disposal costs, and reduce environmental costs.  

How Concrete is Recycled 

The process of recycling concrete basically involves crushing it with equipment that has large impactors and jaws. A second impactor is also used and the screen will remove the particles and dirt from the concrete. There is a second screen where the coarse aggregate is removed. Additional methods like separators, water floatation and magnets are also conducted to remove other concrete components. Pulverizing the recycled concrete is not recommended because the separation process would be hard to complete.  

When recycling the concrete, you also have to use the right equipment. One of the practical things to use is the portable crusher which you can bring in any location. If you consider a concrete crusher, you have to consider some factors too. Make sure it has a powerful electromagnet that pulls the steel from the concrete. Look for the separate picking stations where you can separate loose materials. Consider the control system, do you need the manual one of the automatic one. You can also opt for systems with different jaws, conveyors and cones depending on the concrete type.
