The concrete challenge | TECHNOLOGIST

2020. 11. 23. · With the EU setting a 2020 goal of recycling 70% of construction waste, it is debatable how much of this reuse will be in a degraded form – or instead “upcycled” into new concrete. Heinz says that using old concrete waste as a source of aggregate for new concrete might be a good solution, but there are still some issues that must be considered.

Ways to Recycle and Reuse Concrete

The early phases of many construction projects involve the demolition of concrete foundations, sidewalks, driveways, and other concrete structures, which can leave a contractor with a sizable volume of heavy, dense materials to deal with. Fortunately, concrete can be recycled and reused in many ways. Typically (but not always) the process involves crushing or pulverizing the concrete rubble near the demolition or building site. Choosing the best method often depends on the size and shape of the
