Abstract
A tracer material having an identifiable property associated with a particular type product and/or a particular manufacturer is blended with dry, powder hydraulic cement-based building materials, which set to a hardened product after admixing with water or another hardening agent, to provide the capability of making a simple analysis of the hardened product to determine the presence or absence of the tracer material and thereby positively identify whether the building material used to produce the hardened product was a particular type and/or supplied by a particular manufacturer. The building material can be analyzed in the dry powder form prior to use to make the same type determination.
