analytical chemistry sampling crushing and grinding
Recommendation of RILEM TC 178-TMC Testing and
· When sampling one of the most important needs is getting representative samples. The size of the samples must be large enough to fulfil the sample requirement of the analytical chemistry procedure and to avoid errors due to local heterogeneity for instance between cement paste and aggregate zones whose contributions to the chloride content may be quite different.
