Testing fresh concrete - Sampling Ingestion-build-59651 IdentificationThis European Standard specifies two procedures for sampling fresh concrete, by composite sampling and by spot sampling. NOTE The requirement for remixing the sample before tests on the fresh concrete, or before making test specimens, is included in the relevant standards. When mixing and sampling of concrete is done in a laboratory, different procedures may be required.
