CASEA Calcium Sulphate Flowing Screed and Conventional Calcium Sulphate Screed
This declaration refers to calcium sulphate flowing screed and conventional calcium sulphate screed. 1 kg of the dry mixture prior to adding water on the construction site is used as the declared unit. This dry mixture displays a dry bulk density > 1500 kg/m3. The primary binding agent is represented by bindable calcium sulphate which is hydrated as flowing screed (liquid) or conventional screed (moist) by adding water on the construction site, independent of the processing consistency. The declaration is independent of delivery as a premixed dry mortar, ready-mixed mortar or binder compound only requiring the addition of aggregate or water. Regardless of the fact that cement can also be added as an aggregate, this declaration does not apply for cement screed where cement is used as the primary binding agen. This declaration only applies for screed and binding compounds delivered loose in transport containers, i.e. not in bags.
