This report focuses on how to use residual aggregates from selected danish quarries.It is estimated, that around 15% of all dugged-up produce of sand, gravel, clay andstone in quarries are returned to the pits, due to them not meeting the requirementsestablished by the industry. With regard to the promise of an increase in aggregateconsumption and the decreasing availability which Denmark faces in the not-toodistantfuture, it is becoming an increasingly important necessity to utilise thenatural aggregates in a more local and efficient way.Interviews have been conducted with a local governing body, and local quarry ownersand managers, to understand and map different point-of-views in the quarryingindustry.To understand why the aggregates are disposed of and to find an industrial usefor them, seven types of the disposed products from three different suppliers havebeen acquired to undergo four experiments in laboratory: Visual identification,water content analysis, sieve analysis and compression strength of concrete withthe products used as aggregrate. The results from the experiments are hereaftercompared to the danish versions of European Standards regarding aggregates forconcrete, mortar, unbound mixtures, and bituminous and hydraulically boundmixtures for use in road constructions and surface treatments.The results and comparisons have shown, that only one of the residual aggregatescomplies with the European Standard regarding aggregates for concrete. Theremaining six aggregates do not comply with the standards, mainly due to theparticle size distribution. Therefore, this report recommends a platform for quarryactors for facilitating the selling and buying of residual aggregates internally, so thatresidual aggregates from different quarries can be mixed to alter the particle sizedistribution to comply with the standards.Lastly, questions are raised to the imminent lack of ressources and the handlinghereof, and solutions proposed by the interviewees and found through the literaturesearch are being discussed to showcase the different perspectives on the matter.
