Development of a sample preparation procedure for Sr isotope analysis of Portland cements.

ABSTRACT: The ⁸⁷Sr/⁸⁶Sr isotope ratio can, in principle, be used for provenancing of cement. However, while commercial cements consist of multiple components, no detailed investigation into their individual ⁸⁷Sr/⁸⁶Sr isotope ratios or their influence on the integral ⁸⁷Sr/⁸⁶Sr isotope ratio of the resulting cement was conducted previously. Therefore, the present study aimed at determining and comparing the conventional ⁸⁷Sr/⁸⁶Sr isotope ratios of a diverse set of Portland cements and their corresponding Portland clinkers, the major component of these cements. Two approaches to remove the additives from the cements, i.e. to measure the conventional ⁸⁷Sr/⁸⁶Sr isotopic fingerprint of the clinker
