| Summary: | This document specifies methods for the determination of the cement content Z, aggregate content G and the weight ratio of cement to aggregate (mixing ratio), when the other constituents cement and aggregate are partly or entirely available next to concrete. This method espacially applies if the methods fail according to DIN 52170-2 and DIN 52170-3. This is the case when for example the aggregate contains other acid-soluble components than limestone and/or dolomite (i.e. basalt, diabase, gabbro, granite, greywacke, naturally or synthetically produced lightweight aggregate or if the cements contain acid insoluble components, i.e pozzolan. The aggregate and/or the cements shall be available or there shall be reliable information of the chemical composition of the cement. |
