Determination of composition of hardened concrete - Part 4: Hydrochloric acid soluble and/or insoluble aggregate; materials used for the concrete totally or partly available


This document specifies methods for the determination of the cement content Z, aggregate content G and the weightratio of cement to aggregate (mixingratio), 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.
