Aggregates for quality concrete from debris using ...

To this aim, a modular rapid deployable clearing kit has been designed, clearing (concrete) debris, and processing this into quality aggregates for new concrete to be used in local reconstruction. Since the quality of the initial concrete is unknown, errors can be made when it was produced (e.g. not enough cement, too much water, etc.).
