Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. Studien undersöker hur betongens egenskaper påverkas av olika halter absorptionshämmare. Dels studerades glimmerrikt bergkrossmaterial, soThis master thesis evaluates an absorption-inhibiting admixture to enable the use of demanding aggregate materials in concrete production. This was achieved by investigating how the properties of concrete were affected by different levels of absorption inhibitor. Firstly, mica-rich aggre-gate material was studied, which, due to its high mica mineral content, has a high water absorption rate that i
