Sammendrag
A new admixture is available, to reduce the sludge produced from the cleansing of production and
transportation equipment in the fresh concrete industry. The result is agglomerations of hardening
concrete, that might be utilised for aggregate. Utilisation depends on adequate properties. This
paper reports from investigations on the physical and mechanical properties of the aggregate and
discussions on the performance relative to natural and recycled aggregates and towards
requirements for utilisation. The findings indicate substantial potential for utilisation, supporting the reduction of waste for deposit and development of the concrete industry towards a circular
economy.
