Structural Concrete from Recycled Aggregates
In spite of the amount of construction debris produced every year, recycled aggregates are still not commonly used in the concrete industry. A recycled aggregate concrete—RAC—is not yet allowed by technical codes even though it would greatly help reduce the disposal of debris. This paper considers a construction site that can only be reached by …
